I have to revisit REST authentication for one of my applications that is talking to an external API. Seemed like a good time to make use of the Built In credential management in APEX 23.2 (Oracle - 21.14.0.0.0). The problem I appear to be having is that the external API wants additional fields in the Token Call:
Specifically the grant_type, box_subject_type and box_subject_id (if I post this via Postman, I will get back a token)
But when I set up the credentials via APEX:
There isn't a spot that I can find to add in other parameters. I know that the Token URL is included with the Make_Rest_Request call
l_clob := Apex_Web_Service.Make_Rest_Request(
p_url => final_query,
P_http_method => 'GET',
p_parm_name => apex_util.string_to_table(rest_pars),
p_parm_value => apex_util.string_to_table(rest_values),
p_wallet_path => 'file:' || master.wallet_path,
p_wallet_pwd => Null
,p_credential_static_id => 'box_api_2024'
,p_token_url => 'https://api.box.com/oauth2/token');
(I don't want to hard code the URL here, but that is a different issue for another task).
So, am I stuck managing tokens and authentication by hand or is there some way to sneak the box fields into the oauth2 request?
