Error: http request is unauthorized with client authentication scheme 'anonymous'

Posted on by Mugdha Kelkar 360

Hi All,

We are facing very strange issue while connecting to CRM from Azure Function. Basically, we are trying to create data in CRM using Azure Function, but when record creation counts is more than 15 thousand then somehow we are experiencing below error.

'The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was 'Bearer authorization_uri=login.microsoftonline.com/.../authorize, resource_id=xxxx.crm.dynamics.com/'.'

Any threads to resolve this issue would really appreciated.

Thanks,

Mugdha

    Hi,

    It seems CRM token is getting expired.

    You will need refresh token for every request.
