How to use the AddAuthparameter procedure? - api

Question

I have to add an authorization to a REST request in Delphi.
Can someone give me an example how should it call the AddAuthParameter procedure?
I am doing this code in an onclick event of a button :
authjo, auth1, auth2, auth3, auth4, auth5, auth6, auth7, auth8, auth9, auth10 : string;
authjo := auth1 + auth2 + auth3 + auth4 + auth5 + auth6 + auth7 + auth8 + auth9 + auth10 ;
Restrequest4.AddAuthParameter('Authorization',authjo,TRESTRequestParameterKind.pkHTTPHEADER);
Restrequest4.Execute;
But this does not use thes the Authorization token 'authjo' and i don't know why.
I must have Authorization like this "Authorization Bearer :token" am i not constructing well in the code ?

Answer 1

If the authentication expects a Bearer token, you must add that to your call:
Restrequest4.AddAuthParameter('Authorization','Bearer ' + authjo,TRESTRequestParameterKind.pkHTTPHEADER);

Answer 2

Having messed around with Delphi to access an API (In my case Trakt), I managed to authenticate with OAuth2. But I ran into the very same problem as you did.
I have just asked my question here:
Accessing TRAKT API from Delphi - issues with Bearer authentication [SOLVED]
As I understand it, the root cause it that adding headers like we do, will create a parameter entry that is "Authorize=Bearer [token]" whereas it should be "Authorize:Bearer [token]".
See here:

I have managed to mitigate the issue and would like to reference to that thread.
Also, the tool Fiddler was most helpful to see what my app actually sent and what it got back.
