Hi Viral,

I recommend checking out Front’s attachment example here:

If you still have issues after referencing that example, please write in to api@frontapp.com and our support engineers will be happy to troubleshoot this with you!

Hi Viral,

That endpoint doesn’t accept attachments on requests of Content-Type: application/json.  You must submit your request as Content-Type: multipart/form-data.  The attachment itself should be sent as a binary file with no encoding.

All developer documentation pages describing endpoints that accept attachments, including:
https://api2.frontapp.com/channels/cha_am1le/incoming_messages

won’t produce useable sample requests.  You’ll need to implement those requests using the example located here:
https://dev.frontapp.com/docs/attachments-1
