Messaging inbox integration

Hi, I want to integrate messaging inbox. So I have reached to POST /v1/channels.
The channel creates successfully. But the response is

{
"success": false,
"error": "Failed when querying Provider REST API",
"error_info": "Please check the reference docs in https://developers.pipedrive.com/docs/api/v1",
"additional_data": {
"code": "PROVIDER_API_ERROR"
}
}

but my endpoint from manifest json (getConversation) returns as pipedrive wants

And I cna’t understand what’s the problem from that generic error

Hey @Eduard_Stepanyan , sorry for the trouble. It looks like you are sending value admin as the participant role, but it should be one of source_user or end_user. You can check this doc for more info. Hope it helps🤞
