In order to get API credentials, just shoot us an email at firstname.lastname@example.org.
Let us know your company name and what you're trying to build, and we'll help you decide what authorization flow to use. We'll respond quickly with your API credentials, and you can proceed to the next steps: requesting tokens and calling the APIs!
In general, if you are requesting your own company's data, you will use the client credentials flow. If you are requesting data for multiple companies on behalf of their users, you will use the authorization code flow. You can read more about these OAuth flows on Auth0.
[Soon] You can generate a client credentials grant on the HCSS credentials webpage. Remember to save the client secret somewhere secure; we do not store client secrets and won't be able to retrieve them.
