Authentication & Authorization

The DataGrail Customer.io integration connects using API Key authentication which requires an API Key.

Sensitive Credentials

Publicly exposing your API credentials can allow unauthorized access to Customer.io API endpoints by a third party. DataGrail stores your API credentials encrypted and protected.

---

Limits

Limits in Customer.io are calculated using the leaky bucket algorithm. All requests that are made after rate limits have been exceeded are throttled and an HTTP 429 Too Many Requests error is returned. Requests succeed again after enough requests have emptied out of the bucket.

• DataGrail supports requests throttling to stay within 70-80% of specified service rate limits.
• DataGrail processes API responses with HTTP 429 status to interrupt requests, waiting and retrying (using an exponential backoff strategy).
