API keys
All requests to the Torpedo API (except workspace creation) require an API key passed in the X-API-Key header.
curl https://api.torpedo.co.mz/api/v1/emails \
-H "X-API-Key: tor_your_key_here"
Keys follow the format tor_ + base64url-encoded random bytes.
Key types
Workspace key
Created automatically when you call POST /api/v1/workspaces. Can send from any verified domain in the workspace.
Domain-scoped key
Created via POST /api/v1/auth/keys with a domainId. Can only send from that specific domain. Use these for multi-tenant setups or to isolate sending by domain.
Getting your key
Keys are returned once only at creation time and cannot be retrieved again. If you lose a key:
- Revoke it via
DELETE /api/v1/auth/keys/{id}
- Create a new one
Security best practices
Never expose API keys in client-side code, public repositories, or browser environments. Keys
grant full send access on behalf of your domain.
- Store keys in environment variables (
TORPEDO_API_KEY)
- Use domain-scoped keys when possible — limits blast radius if a key leaks
- Rotate keys periodically using the revoke + create flow
- Set up webhooks to monitor for unexpected sending activity
