I am trying to send a GET request to https://api.accounting.sage.com/v3.1/contact_allocations to return all contact allocations. The only header I am adding is an authorization header containing the access token in the form "Bearer xxx...xxx"

I have managed to request an authorization code, and convert it into an access token. However, when I then make a request using the access token, I get an "Unauthorised Access" error, the JSON response being:- [{"$severity":"error","$dataCode":"AccessTokenVerificationError","$message":"Access token is invalid (JWT malformed or missing).","$source":"Authorization"}] I am not doing any encoding or decoding. I am simply using the access token as it is presented to me. Can anyone tell me what is going wrong?

Thanks!!! It is a pity the official documentation cannot include such a simple, but critical bit of information.
