Custom connector Invalid CORS request problem

(0) ShareShare
ReportReport
Posted on by 3

I'm getting 403-error with "Invalid CORS request" in a custom connector for the PUT and DELETE requests. There is no issue on API side as it works fine with the Microsoft flow and the postman.

The error is occurring while testing in the connector (Edit mode of MS Connector)

 

I'm using basic authentication to test the connector.

    Hi @Nadir_Riyani 

     

    403 is not a connection issue. It's Forbidden, meaning that there's something wrong either with the permissions or the authentication. 

     

    Can you please share the Power Automate and obfuscate anything private that you can't share so that I can have a better understanding of what you're trying to do and the issues.

     

    If I have answered your question, please mark your post as Solved.
    If you like my response, please give it a Thumbs Up.

    Cheers
