HTTP Request GET 401 Error


My scenario is to get Data from Web thought of using REST API calls and get the items. But when I use HTTP Request activity and pass the API uri facing an error 401.

I can get response using other application like POSTMAN . Also used simple authentication and provided credential. Still same error. Kindly let me know if you have solution for this issue ASAP.


What type of authentication is the remote service expecting? (Basic, Negotiate, NTLM, OAuth, other…), When you set up your Postman request what are you using?

I recently interacted with a semi-REST API, that is expecting to Negotiate or NTLM, but would reject Basic.

I ended up adding the credentials (Add Credential) to the Windows Credential Manager and leaving the authentication properties for the HTTP Request activity unset.
