Set up webhook receiving, customer webhook delivery, endpoint management, replay, alerts, and API access.

Receive vendor webhooks, forward matching events to your app, investigate delivery failures, and replay stored events.

Step-by-step setup for Stripe, GitHub, Shopify, Slack, Twilio, SendGrid, and custom webhook sources.

Send webhooks to your own customers with apps, recipients, event types, a hosted portal, and delivery attempts.

Create API keys, call the backend API, understand scopes, and download the OpenAPI spec.

Connect approved agent clients so they can inspect webhook health and start replay after you authorize access.

Use attempts, backoff, pausing, filters, and replay to recover after an endpoint or handler problem.

Send missing-event, delivery failure, stalled endpoint, and retry backlog alerts to Slack or webhook channels.

Manage workspace access, API keys, signing secrets, endpoint signatures, and payload visibility.

Read workspace volume, success rate, latency, source health, destination performance, and recent failures.

Invite teammates, separate access by team, and keep source ownership clear as the workspace grows.

Choose the right path

Use Developer → Inbound when Stripe, Shopify, GitHub, or another vendor sends webhooks to your product.
Use Developer → Outbound when your product sends webhooks to your customers.
Use Replay after you fix a failed receiver and need stored events sent again.
Use Alerts when a person or system should know about delivery failures or missing events without checking the dashboard.
