Image Capture and Transcription API Query

Contact Center Zoom Virtual Agent
1

I am developing a custom solution using Zoom Virtual Agent (ZVA) where customers provide image inputs during chat interactions. However, ZVA does not support image uploads out of the box, as confirmed in my previous case with you. In the CX Analytics tab > Logs > Transcripts, I can see the chat history, including attached images , which appear in the UI. To work around this, I want to programmatically fetch the transcript and the image attachment using APIs, as text responses can be passed via variables, but images require API access for processing (e.g., in AWS Lambda). I have explored the following APIs with a Server-to-Server OAuth app (scopes include contact_center:read:engagement:admin and contact_center:read:inbox_messages:admin): GET /contact_center/engagements/{engagementId}/events Response: {“code”: 7001, “message”: “Only voice and video channels are currently supported.”} Limitation: Does not support messaging channels. GET /contact_center/messaging/messages?engagement_id={engagementId} Response: {“code”: 11006, “message”: “Integration Messaging Channel feature is not enabled for this account.”} My goal is to retrieve the full transcript, including image attachments (as URLs or downloadable files), to integrate into our custom flow. Could you please advise on: The correct API endpoint or method to fetch messaging attachments? How to enable the “Integration Messaging Channel” feature if needed? Any beta/private APIs or upcoming features for this as of December 2025? And also, is there any way to disable that message that we get whenever we upload an attachment that " We are unable to read the attachment etc…", I couldn’t find any setting for that as well. May be we can alter that.

Thanks for reaching out to us about this issue.
I am not familiar with the Integration Messaging Channel feature you are mentioning, but here is a support article that will help you do this:
