GetResponse API
GetResponse runs a self-serve REST v3 API: generate a key in account settings or use OAuth 2.0 for third-party apps, with webhooks for subscribe, open, and click events. Mind the quirks: unused keys expire silently after 90 days and rate limits only surface as production 429s.

Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
