Migrating to v3

What changes when you move a v1 or v2 integration to API v3: credentials, errors, IDs and asynchronous operations.

API v2 and API v1 receive fixes only. They keep working for the integrations that use them, and new integrations should start on API v3. Their guides and references stay available: API v2 and API v1.
