Generate API keys for service-to-service access
Create API keys from Settings and store them in your secret manager. Keys are shown in full only once.
Use the Authorization header with Bearer tokens for scripted workflows.
- Pro plan supports 1 API key
- Enterprise plan supports 10 API keys
- Rotate and delete keys when ownership changes
Automate common alias operations
Use API endpoints to create addresses, list threads, fetch thread details, and send replies from your aliases.
This is useful for support routing, CI notifications, and internal tool integrations.
- Create aliases on selected domains
- Read inbox threads and latest message snippets
- Reply or compose outbound messages from allowed addresses
Subscribe to outbound webhook events
Enterprise users can register HTTPS webhook endpoints and subscribe to email.received, email.sent, and thread.created events.
Each delivery includes timestamped HMAC signatures so your app can verify authenticity before processing.
- Up to 5 webhook endpoints on Enterprise
- Signature headers include timestamp and digest
- Delivery logs are visible in settings
Design for reliable processing
Return 2xx quickly and move heavy work into background jobs. Track event identifiers to handle duplicates safely.
For critical workflows, monitor webhook delivery status and alert on repeated failures.
