Which API is mine?
One question decides it: do you appoint agencies, or are you the agency? The answer gives you your path prefix, the versions available to you, and the
errorType you get back if you call the wrong surface.How this site is organized
Conventions you need either way
Authentication
OAuth M2M and Restricted Access Tokens. Both methods reach the same endpoints, and a credential belongs to one organization.
Environments
Sandbox and live hosts. Both environments serve both APIs.
Versioning
What
v1 and v2 mean, and which version each surface has.Error handling
The error envelope, and why you branch on
errorType rather than on message text.
