I have a requirement to invoke a Google API using OAuth2 authentication with RSASHA256 encryption.
Is this possible using RPG on IBM i?
Any help appreciated. Thanks
BTW, Today we use YAJL for building JSON & HTTPAPI to transport payload.

Re: Invoke google api using JWT oauth2 with RSASHA256 encryption
Hello,
Yes, its possible.
Midrange Dynamics has a product called MDRest4i that has routines to generate JWT tokens using RSASHA-256 that are written in RPG and are aimed at RPG programmers. So that might work, assuming your OAuth2 is using JWT tokens (This is commonplace.)
You could also write it yourself using the system APIs. This is a significant amount of work, though, you'll have to research how the tokens work, how the OAUTH2 architecture works, and write it all.
