External Notification Providers

The Courier REST API enables sending messages, retrieving message details, and managing user profiles and preferences across your audience.

Intro

Courier REST API

Authenticate with the Courier REST API using either Bearer tokens or Base64-encoded Basic Auth credentials, ensuring secure access to send notifications across supported languages.

Authentication

Courier supports idempotent [idempotency](https://en.wikipedia.org/wiki/Idempotence) POST requests using an Idempotency-Key header to safely retry without duplication, storing results for 24 hours (configurable up to 1 year).

Idempotent Requests

Most Courier APIs have no rate limits, but some—like List, Event, and Brand creation—are limited to 20 requests per minute. Login, invite, and category actions have additional limits.

Rate Limiting

Courier uses Notifications (message templates), Integrations (delivery providers), and Channel Rules (send priorities) to manage how messages are sent across channels like Slack, email, and SMS.

Courier Vocabulary

Courier’s Send API delivers messages asynchronously to users, lists, or audiences using either templates or ad-hoc content, with flexible routing and support for attachments.
