ADF: Error code - RestCallFailedWithClientError

C Sharleen 0 Reputation points

Copy data from REST API (used a dummy api) to a CSV file. Error generatedUser's image

Created a pipeline - source (REST) added the dummy API link ( - POST Register Successful) and the appropriate credentials then for sink (CSV file).

Whichever dummy API with authentication I use, getting the same error as above. When I try dummy APIs without any authentication then the pipeline is successful, so the authentication part generates some kind of an error.

    Hi C Sharleen, Thank you for posting query in Microsoft Q&A Platform.

    If your API has an authentication logic then only you should consider using it. In your case your APIs are dummy which can work with Anonymous authentication. So please use only Anonymous authentication.

    If you use any other authentication which is not supported by API then you end up with this kind of error.

    Hope this helps. Please let me know if any further queries.
