OData APIs are not working

Posted on by 30

Odata and OData V4 APIs are working fine in web browser but in postman it is throwing 401 unauthorized error. I have tried with both Basic Auth and NTLM Authentication.

    Yes I am using "Web Service Access Key" as password in the basic Authentication. If I check the windows event log it says "This license is not compatible with this version of Business Central.". My question is if it is a license issue then the API shouldn't work in web browsers.

    Did you use the "Web Service Access Key" as the password in the basic Authentication? Works ok for me in Postman.
