The capabilities behind the workflow.

API keys

Create revocable workspace API keys. Raw credentials are displayed once and stored only as a hash.

Signed webhooks

Send selected product events to your systems with timestamped HMAC signatures and delivery history.

Delivery history

Inspect webhook delivery attempts, response status, retry count, and error details from the workspace.

Create credentials without storing the raw secret

Outreap shows a new API key once, stores a SHA-256 hash, and exposes only a short prefix in the product afterward.

Workspace-scoped keys
One-time raw credential display
Revocable credentials
Last-used timestamp

Choose the events your endpoint receives

Webhook subscriptions store an endpoint, selected event types, signing secret, active state, and delivery records.
