Sending Interactive Messages

Add the necessary dictionaries and fields in your request to send an interactive message.

To send an interactive message, use the type value of interactive and include the interactiveData field in the message JSON. The interactiveData field is a dictionary that describes the features to use. The dictionary also contains data that Messages passes to the feature.

Below is a sample interactive message showing all possible values.

{
    "type": "interactive",
    "interactiveData": {
      "appId": app-store-id,
      "appName": "Name of the App",

    "locale": "Language in ISO 639-1",
    "id": "A UUID string that identifies the message"
}

Receiving an Interactive Message

Download the interactive data when a user's reply contains a large attachment or payload.

A user’s reply to an interactive message may cause the Interactive Message Dictionaries in the message JSON to grow beyond 10 KB in size. When this happens, the Messages for Business service uploads the original reply message and sends a reference pointer, interactiveDataRef, to the original interactive data response. The keys in the interactiveDataRef contain the pointer to the Messaging service where the payload, or set of large assets, is contained.

As an MSP, your platform must download the reference pointer to obtain the original interactive data response from Messages for Business.

Identify a Large Interactive Data Payload

When your MSP platform receives a message of type interactive from the Messaging service, the MSP platform inspects the message JSON, looking for the interactiveDataRefkey (see below). Its presence indicates that the received message is an interactive data reference and contains a payload to download. For more details on an interactive data reference in the message JSON payload, see Receiving Messages from the Messages for Business Service.

Below is a large interactive data payload.

{
    "interactiveDataRef": {
        "url": "https://p61-content.icloud.com/M58C0A1A2EB62B6E899B4F28996E8DA229E1914295299C39944B2F2CA7482AE50.C01USN00",
        "bid": "com.apple.messages.MSMessageExtensionBalloonPlugin:0000000000:com.apple.icloud.apps.messages.business.extension",
        "signature-base64": "gdYWyD3loBxhiXGaXSDhdDDGMeHr",
        "key": "00c0d1827fdc858fe7b42421de1fb289c2ee0a9463d787ce4f118506f970bd6e38",

        "owner": "M58C0A2A1EB62B4E859B4F28996E8DA229E1914295299C39944B2F2CA7482AE50.C01USN00",
        "size": 101267
    },
    "sourceId": "",
    "destinationId": "",
    "v": 1,
    "type": "interactive",
    "id": "80c72dab-dc7b-4750-8fae-ee7a90fae0cb"
}

Download the Encrypted Payload

When the interactiveDataRef key is present, download the encrypted payload from Messages for Business using the following method:

1. Using the fields in the received interactiveDataRef key, retrieve the URL to the payload by calling the /preDownload endpoint. See Getting an Attachment's URL.
2. Download the payload by sending a GET request to the URL returned by /preDownload.
3. Decrypt the downloaded file. See Downloading and Decrypting an Attachment.

For improved performance, the interactive data reference can be reused for sending another request with the same content. However, it has the same 30-day expiry as payloads like an image, PDF, or other file type, as described in Sending Messages with Attachments. Although you can reuse requests with interactiveDataRef in the next send request, you must immediately process responses with interactiveDataRef and cannot reuse them.

Decode the Payload Data

The decrypted payload of the downloaded file yields encoded data. To decode the data, the MSP platform must send a POST request to Messages for Business’s /decodePayload endpoint with the request body containing the encoded data from the previous steps. The response body from the /decodePayload request is a decoded interactive data dictionary, which is the original interactive data dictionary that the user sent. For more details, see Decoding Interactive Data Payloads.

Decoding Interactive Data Payloads

Convert an interactive data reference into an interactiveData dictionary by calling the /decodePayload endpoint to decode large interactive data payloads received from Messages for Business. The endpoint takes the encoded attachment and returns the JSON dictionary representing the interactiveData dictionary. For more information, see Receiving Large Interactive Data Payloads.

Quick Reply Message

Provide a simple way for the user to make an inline choice with a single tap during an ongoing conversation. You can have between two and five customizable choices, and the user can select only a single item.

The summaryText should not be considered as the introduction message to the quick reply message. You should use a text message to offer the user to choose one of the items.

Quick reply is an interactive message. Due to its simple structure, it doesn't have receivedMessage or replyMessage fields similar to other interactive message types.

This feature requires iOS 15.1 and macOS 12.0 or higher. For more information, see capability-list under HTTP Headers.

Processing Payment Requests

If you support Apple Pay payment requests, you need to obtain the Apple Pay payment token from the customer's device. To receive this token, implement the payment gateway endpoint. Apple Pays calls this endpoint to send you the token and ask that you process the transaction. The URL to the endpoint must match the value in the paymentGatewayUrl field defined in the ApplePayEndpoints dictionary. For more information, see Sending an Apple Pay Payment Request.

Request

POST https://msp.example.com/paymentGateway

Parameters

The request body is a JSON dictionary with the following keys.

Key	Description
payment	A dictionary containing payment information. For the list of payment dictionary keys, see Payment Dictionary.
requestIdentifier	An identifier for the request. Messages for Business includes the identifier in its response to the MSP platform.
version	The version number of the message extension schema; the version should be 1.0.

Note

The v: 1 key-value pair and the version: 1.0 pair both indicate version numbers.

The v indicates the version of the REST API that corresponds to the endpoint version at https://mspgw.push.apple.com/v1.

The version inside of the interactive message indicates the version of the requested list picker implementation. Currently, both have only a single version. Apple architected the system to increase the list picker and other interactive message components as a higher number than the underlying API.

Also the v is an integer data type while version is a string.

Payment Dictionary

Use the following payment dictionary keys.

Key	Description
billingContact	The customer's billing contact information. For more information, see billingContact.
paymentToken	The payment token. For more information, see Payment Token Format Reference for more information.
shippingContact	The customer's shipping address information. For more information, see shippingContact.

Sending an Apple Pay Payment Request

A payment request starts when a customer service agent with the business asks you to send a payment request to a customer. You should create a data dictionary to collect and store information about the payment request.

The first piece of information to collect is a payment session object. To get it, ask Apple Pay to start a new payment session (see Requesting an Apple Pay Payment Session). Apple Pay returns a payment session object which you add to the Payment.MerchantSession dictionary in the data dictionary.

Next, add the ApplePayPaymentRequest dictionary keys to the data dictionary. This is where you specify transaction details such as the purchase amount, payment processing capabilities, available shipping methods, and a list of items or services purchased. You can also request billing and shipping address information through the ApplePayPaymentRequest dictionary.

Finally, add the ApplePayEndpoints dictionary keys to the data dictionary. This dictionary identifies the endpoints needed to process the payment and receive any updates a customer might make before confirming the payment, such as updating the shipping address or changing the shipping method.

After constructing the data dictionary, send it to Messages for Business as part of an interactive message (see Sending a Custom Interactive Message). Messages for Business forwards the payment request to the customer's device, and the customer authorizes the payment from the Apple Pay payment sheet using Touch ID or Face ID. The device then sends the payment information, including the encrypted Apple Pay token and any requested customer contact information, to the paymentGatewayURL endpoint listed in the endpoints dictionary. After processing the payment, the merchant sends the transaction results to the customer's device, which in turn sends the results to you to let you know the payment request is complete.

Authentication Message

The new built-in Authentication flow uses the latest OAuth 2.0 Authorization Framework to allow implementation of latest authorization flows, and compatibility with OpenID Connect. The update also includes changes to improve security in the OAuth 2.0 flow.

In the new flow the device initiates the authorization flow and the business or Messaging Service Provider (MSP) is responsible to complete the authorization flow.

Requirements

You need an Apple device running iOS 16, iPadOS 16 or macOS 13 to test the new built-in Authentication flow. For more information see Apple Developer Downloads.

Sending an Authentication Message

The new authentication flow does not require private/public key generation and follows the OAuth specification to redirect the user to the ‘redirect_uri’ provided. It removes the requirement to provide the client secret on the payload, and is compatible with OpenID Connect.

Following are the responsibilities for the Business & MSP:

• The Business & MSP needs to use the state to verify the session and user for authentication.
• The Business & MSP is responsible for retrieving the Access Token (ID Token) to complete the authentication.

URL

POST https://mspgw.push.apple.com/v1/authenticate

End Point Registration

Businesses supply authentication details about the OAuth provider, including authentication endpoint URLs, client identifier, and business information verified by Apple Business Register. Changing any of these authentication parameters requires additional verification and approval from multiple customers that own or administer the business.

Initiate Authorization Flow

Initiating the authorization flow requires sending a POST request to the /v1/authenticate endpoint hosted by Messages for Business with the authentication message in the request body. You must secure the authentication endpoint before sending a request from a business to the customer. When the OAuth request is sent to the provider, the endpoints must present a valid Extended Validation (EV) certificate for a successful authorization.

The authentication request is an interactive message. When composing an authentication request, include the InteractiveData Properties for New Authentication Message to describe the behavior and content of the authentication request.

You can send the New Authentication Message to a customer’s device with the auth capability announced, which is included in the capability-list header of the message request. Devices that support the New Authentication Message will have the value AUTH2 in the capability-list header. For more information about the Authorization header field, see Authorizing Messages.

InteractiveData Properties

The New Authentication Message is an Interactive Message Type, which has the following properties. See Common Specifications for interactive messages types.

InteractiveData Dictionary

Name	Type	Description
bid	string	REQUIRED. com.apple.messages.MSMessageExtensionBalloonPlugin:0000000000: com.apple.icloud.apps.messages.business.extension
data	object	REQUIRED. A collection of name and values used for interactive message types.
receivedMessage		REQUIRED. A dictionary with information telling the Messages app how and what content to display the received message bubble. See ReceivedMessage.
replyMessage		REQUIRED. A dictionary with information telling the Messages app how and what to display in the reply message bubble. See ReplyMessage.

InteractiveData.Data Dictionary

Name	Type	Description
images	array	An array of image dictionaries.
requestIdentifier	string	REQUIRED. An identifier for the authentication request.
version	string	REQUIRED. A numerical version number of the message extension schema. Set 2.0 for the New Authentication Message.
authenticate	object	REQUIRED. An object to construct the authorization URL.

InteractiveData.Data.Authenticate Dictionary

Name	Type	Description
oauth2	object	REQUIRED. A dictionary that describes the authentication request.

Data.Authenticate.Oauth2 Dictionary

Name	Type	Description
responseType	string	REQUIRED. A string indicating the type of authentication request. Set code for authorization flow.
scope	array	REQUIRED. An array of scope items that specifies the scope of the request.This dictionary entry gives the exact fields of data that the authentication service provides to the client requesting the authentication.
state	string	REQUIRED. A string indicating the state of the authentication request.
redirectURI	string	REQUIRED. A string representing the redirect URL that the OAuth provider redirects the user.
additionalParameters	string	A string value that you can add on the authorization URL query parameter.

Generating state Value

The state is used to prevent request forgery attacks. It is important that you create a session token that is unique to that session and constructed with a high quality random number. Use the state to link the user with the session using the OpaqueID provided on each message.

For example :

3D138r5719ru3e1%26AQAAY+jbFom1SW+wCRR2yq3eh+k0VtLQrTRnVPYF9V2fQ5LM5c53uamshW1DYOF2d+jnENvo5c1sV+UWvjV2+rmGwJ+q2GsvPziBDsgw+Jps7YjbvqwtB+SVdLV2EJC4H0l3cVj8tMuEC0gSw3lGeRP4z+QhhPQ=

The above example is created with

<Random string using cryptographic> & <OpaqueID>

Do not use a static value on the session token that an attacker could easily identify.

Using this format you can confirm the session token for anti-forgery and the OpaqueID with requestIdentifier to link to the user.

Additional Parameters

The additionalParameters allows to add additional query parameters to the authorization URI request. This allows specific parameters required for custom OAuth providers.

For example:

parameter1=01&parameter2=02

Complete the OAuth flow

Once the user completes the authorization, the user is redirected to the redirectURI with the state and authorization code to complete the OAuth 2.0 flow. The Business & MSP are responsible to complete the authentication flow to retrieve the access token or id token for the user authentication.

Note

For more details on OAuth 2.0 authorization code flow, please check the OAuth 2.0 RFC.

Finishing the New Authentication Flow

Once the OAuth flow has been completed, the Business and MSP can finish the flow by redirecting the user to the following URL scheme which closes the window and bubble. After the flow is complete, be sure to send a welcome message to the user.

URL Scheme

messages-auth://?

Query Parameters

Query Name	Parameter	Description
status	success, failure, cancel, unknown	REQUIRED. A string that describes the authentication status.
error_code	string (numeric)	A numeric string to provide reference of a specific error.

Examples:

302 messages-auth://?status=success

302 messages-auth://?status=failure&error_code=400

Authentication Webhook Event

The authentication webhook event is sent when closing the window with status as success or failure using the URL scheme. See Finishing the New Authentication Flow for more details.

Authentication Webhook Payload Properties

Using Password AutoFill to Authenticate Users

Provide customers with an easy solution to perform authentication on their iOS devices.

Supporting the Password AutoFill feature requires that the authorization input element annotate the autocomplete HTML attribute in the following format:

<input autocomplete=”value”>

Possible values for the autocomplete attribute are username, current-password, new-password, and one-time code. For more information about these values, see Enabling Password AutoFill on an HTML Input Element.

Note

Password AutoFill is supported in Safari 12 for iOS 12 and later, and Safari 12 for macOS 10.14 and later.

After the customer has been authorized, the system sends an OAuth response. In this step, the customer’s device is redirected to a URL that triggers a login form using an existing third party login system. For more information, see Password AutoFill.

iMessage App

Below is the iMessage app, also referred to as CustomInteractiveData, request body. The request body is based on InteractiveData.

Name	Type	Description
InteractiveData		Custom InteractiveData

InteractiveData

The CustomInteractiveData dictionary keys. In addition to the keys from the BaseInteractiveMessage dictionary, the message can also include the keys from the CustomInteractiveData dictionary.

Name	Type	Description
appIcon	byte	REQUIRED. A Base64-encoded string representing the app icon of the iMessage app. The Messages app displays the icon when a customer's device receives a iMessageApp message that uses an iMessage extension not installed on the device. The MSP platform must include this key when sending an interactive message that uses an iMessage extension provided by the business. Don’t include this key when sending an interactive message that uses a Messages for Business iMessage extension. appIcon should be smaller than 15kb. For more information, see Sending Custom iMessage app.
appId	string	REQUIRED. The App Store identifier of the iMessage app. The MSP platform must include this key when sending an interactive message that uses an iMessage extension provided by the business. Don’t include this key when sending an interactive message that uses a Messages for Business iMessage extension. For more information, see Sending Custom iMessage app.
appName	string	REQUIRED. The name of the iMessage app. The MSP platform must include this key when sending an interactive message that uses an iMessage app provided by the business. Don’t include this key when sending an interactive message that uses a Messages for Business iMessage app. For more information, see Sending Custom iMessage apps.
receivedMessage		REQUIRED. A dictionary with information telling the Messages app what content and how to display it in the received message bubble.
replyMessage		REQUIRED. A dictionary with information telling the Messages app what and how to display it in the reply message bubble.
URL	string	REQUIRED. A URL string containing data that the Messages app sends to the iMessage app.
useLiveLayout	boolean	REQUIRED. A Boolean that determines whether the Messages app should use Live Layout. The default is true. Default: true

InteractiveData.ReceivedMessage

A dictionary with information telling Messages how to display the received message bubble and what content to include. For more information, see ReceivedMessage.

object InteractiveData.ReceivedMessage

InteractiveData.ReplyMessage

A dictionary with information telling Messages how to display the reply message bubble and what content to include.

object InteractiveData.ReplyMessage

When the MSP platform sends a custom interactive message, the contents of the title and subtitle may not show up on the response if the customer overwrites these fields. For more information, see ReplyMessage.

Sending a Custom Interactive Message

Provide a unique user experience with custom interactive messages.

You can use your custom interactive message—by setting the bid, appId, appName, and appIcon to reference your extension.

When sending a custom interactive message, use the type value of interactive and include the interactiveData field in the message JSON. The interactiveData field is a dictionary that describes the iMessages extension to use. The dictionary also contains data that the Messages app passes to the extension.

To control the appearance of the interactive message that Messages displays on the customer’s device, use the receivedMessage dictionary. Note that the Messages app ignores the imageIdentifier and style keys when using a custom interactive message. For the list of received message dictionary keys, see receivedMessage dictionary.

Form Message

Messages for Business Forms allow you to create rich, multipage interactive flows for users on iOS and iPadOS devices using a single JSON payload. This document provides the Forms specifications, along with example outbound and inbound JSON payloads.

You and your brands may already have ideas which could benefit from this type of interaction. Below are some example use cases:

• Triage flows
• CSAT Survey
• Account creation or service sign-up

Known Issues

• When a user task switches out to another app and back to Messages, the form closes. The user must tap to re-open the form. The form resets and the user has to re-enter their responses.

Because a user may have to re-open the form and re-enter their responses, we recommend you give less complicated use cases that provide quick answers through a simple triage menu. For example, if you use a technical support triage, the following choices appear:

• Did you plug it in?
• Did you turn it on?
• Is the green light flashing?

Form Specifications

The specifications below define the content of the JSON payloads used to render the Form on user devices. For JSON examples, see the Sample Request Payload and Response Payload.

Request Payload

The type of interactiveMessage that initiates the experience is dynamic.

Field	Description
version	REQUIRED. Should be 1.1 or the specified value when the feature launches.
template	REQUIRED. Type is 'messageForms'. Tells the client which template to use to render the view.
data	REQUIRED. Place all the data in this field.

Data Dictionary Objects

Object	Description
splash	Shown at the start of the form. When using splash, ensure the appropriate fields listed below display: -header: If set, it displays in bold the title on the page underneath the image. -splashtext: Use this to display the body copy for the page. -buttonTitle: REQUIRED. Text on the button shown on the page. If buttonTitle is missing then this view doesn't display and continues onto the first module. -imageIdentifier: Image to be shown at the top of the view.
startPageIdentifier	REQUIRED. Identifier for the starting page of the form. Must match one of the string identifiers for the configured pages. See pageIdentifier under pages below.
private	Defaults to false. Boolean value indicates whether to mark the response as private. If value is true, the response object contains this property (interactiveData > data > dynamic > private).
showSummary	Defaults to false. If set to true then it shows the summary of all the selections made within the form.
pages	REQUIRED. An array of different pages to be shown in the form. Every page object has following common objects. -pageIdentifier: REQUIRED. A unique identifier, as a string, for the page being shown, that is less than 20 characters in length. Do not reuse. Ex: "firstNamePage" or "0001". -type: REQUIRED. Use one of the following values: select, picker, datePicker, or input. -title: If set this displays the title in bold on the page. -subtitle: REQUIRED. Use this object to display the question for the page. -nextPageIdentifier: REQUIRED except for single select option page, where you specify the nextPageIdentifier within each of the item objects. If a page does not have a nextPageIdentifier set on it, the client assumes the current page to be the final page and proceeds to send or provides a summary page based on the data. This is a unique page identifier to show the next page. -submitForm: A Bool value placed on the pages to denote the end page of the form. Since multiple pages can act as an end page, this object can be set on multiple pages.

Types of Pages

Pages is an array of page elements and there needs to be at least be one page to trigger the Form experience.

Page Type	Field	Description
select	multipleSelection	A Bool value that defaults to false or singleSelect. Set to true to enable multipleSelection on the page.
