Hi Hari329 -
you will need to get initially set up via Lithium Support (which I believe you aleady did) - and then follow the steps described in the guide. It is a classic OAuth handshake to obtain an access token and a rfresh token and you will need to issue the calls according to that flow as described in our knowledge base article and also on other resources available online. I hope this helps, if not please get in touch with our Support department and they may be able to guide you further.
Thanks,
Hi Hari329
further to the above. The documentation mentions the following
Using the authorization grant flow via a back-end API call The authorization grant flow assumes that a web browser is involved during authentication. If you want to use a back-end API call for OAuth, create an API-only user with appropriate permissions to make the API calls. This API-only user must login once through the community using the authorization flow to receive access and refresh tokens. From there on subsequent authenticated, backend API calls can be made using the tokens.
What that means is, even if the user will be used for back end calls, they will still need to go trough the standard OAuth interactive exchange for the first login, to make sure that you can get a valid access token and refresh token for that user. The below diagram (from the KB page) depicts the interactive exchange (which is the same used for normal, non API users)
At the end of the process (which can be initiated with any suitable HTTP client, manually) you will have obained an access token and a refresh token and you can then store them in your application for subsequent calls.
SuzieH - it looks like our KB page may need some more detail to avoid confusion around this manual step required for backend users. Is that something you can help with?
Thanks,
