Webhooks are generally available

Webhooks have been in beta since 0.9.0, and after four months of feedback they are now generally available for every plan.

#Added

• Signed payloads. Every delivery now carries an X-Relay-Signature header, an HMAC-SHA256 of the body using your endpoint secret. Verify it in one line with relay.webhooks.verify(payload, signature, secret).
• Delivery inspector. The dashboard shows the last 30 days of deliveries per endpoint, with request and response bodies, timing, and a one-click redeliver button.
• Event filtering. Subscribe an endpoint to specific event types instead of the whole firehose. Existing endpoints keep receiving everything until you edit them.

#Improved

• Retries now use exponential backoff with jitter (up to 8 attempts over 24 hours) instead of three fixed retries. Dead deliveries surface in the inspector with the final failure reason.
• Endpoint secrets can be rotated without downtime: both the old and new secret validate for 24 hours after rotation.

Upgrade with npm install @relay/sdk@1.2 or see the configuration guide for the new webhooks block.
