Hi @FaizullahShaik - I suspect you’re using a Client Credential flow, which then requires a user context for the actual SCIM request (not the OAuth request). I’m not sure it’s possible to add headers to the SCIM request; so, you could try the Refresh Token flow passing the user context in the initial Authorization Code Grant OAuth request (outside ISC). Depending on the expiry of the refresh token, though, you may need to look at Custom Authentication see Refresh token renewal - #8 by pulatoi
