Hi Everyone, 

We are using unauthenticated web messaging, and during the conversation, we collect the customer's email address. I would like to search for external contacts using this email and, if a match is found, assign the corresponding external contact profile to the conversation.

I plan to achieve this using the API:
/api/v2/externalcontacts/conversations/{conversationId}

However, the body of this API request requires the communicationId field, and I'm unsure how to obtain it. I attempted to use the participantId as the communicationId, but this did not work. Could you clarify how to retrieve the correct communicationId for this purpose?

Hello Karthik,

The communicationId is the sessionId of the participant, so for an incoming message interaction you can use

/api/v2/analytics/conversations/${input.conversationId}/details

using Input Contract (String) conversationId and Output Contract (String) communicationId

and the following translationMap

{  "translationMap": {    "communicationId": "$.participants[0].sessions[0].sessionId"  },  "translationMapDefaults": {    "communicationId": "\"NOT FOUND\""  },  "successTemplate": "{\r\n \t\"communicationId\": ${communicationId}\r\n}"}
