Authorisation

Good morning team, I hope you are doing great. I am having some concerns if you can help me:What is the role of bc-authorize and CreateOauth2Token ? (I didn’t understand how it happens in real time, or what is its use).what is the difference between CreateOauth2Token and CreateAccessToken?Why do I need bc-authorize and CreateOauth2Token if I can make my requests only with CreateAccessToken?

Sandbox API Testing

Can the sandbox API be tested on a application? When I send a call to the requesttopay endpoint I get a server error. Secondly collection widget display but doesn’t work and when I tried to create Oauth 2.0 token I get Authorized as status code and error of “invalid client”. I also want to know how I can place the API user key and API key on the authorization field after encoding to base64.

How do I generate the Consent Auth Request ID used in the CreateOauth2Token endpoint?

I downloaded the postman collection of APIs. However, in the variables, the consent request id is already defined. I was wondering how it is generated in the testing sandbox. I want to use it when creating an Oauth2 token which I later use in other endpoints that require it.
