Hi maheswara ,
Could you please provide more details about the error? It's a bit vague and could refer to various issues. Would you mind sharing the specific error message for clarification?
The preview shows the since multiple documents can be streamed, each document being streamed is a map. The REST POST snap will take each document and write it out to the endpoint, as a map. You can change the POST endpoint to a test endpoint created in a service like https://requestb.in/, to verify whether the right data is being posted.
The Zendesk API error response would have more details. It is possible the right content type was not set, add a HTTP Header in the POST snap, with key “Content-Type” and value “application/json”
