Webhooks as a Service for Your Product
Send reliable webhooks to your customers without building delivery, retries, signing, and a management UI yourself. Applications, endpoints, event-type subscriptions, circuit breakers, and an embeddable customer portal — all managed.
How Outbound Webhooks Work
Three steps from your backend to your customer's endpoint
Create an Application
One application per customer integration. Define the event types your product emits so customers know exactly what they can subscribe to.
Send a Message
Post a typed event to the API or SDK. Hookbase fans it out to every endpoint subscribed to that event type, signs each delivery, and retries failures with backoff.
Monitor & Replay
Inspect attempt history and response codes per message, filter delivery history down to a single endpoint, and replay any failed message once the far side is fixed.
Everything a Webhook Platform Needs
The parts teams underestimate when they build outbound webhooks in-house — signing, endpoint health, secret rotation, and the customer-facing UI.
Applications, Endpoints & Subscriptions
Register an application per customer integration, give it one or more delivery endpoints, and let each endpoint subscribe to the specific event types it cares about. No fan-out of irrelevant traffic.
Standard Webhooks Signatures
Every delivery carries webhook-id, webhook-timestamp, and webhook-signature headers per the open standardwebhooks.com spec — so your customers verify with any standard library instead of a proprietary SDK.
Circuit Breakers per Endpoint
Configure failure and success thresholds plus a cooldown period. A flaky customer endpoint gets tripped open automatically instead of being hammered forever, then closes itself once it is healthy again.
Secret Rotation with a Grace Period
Rotate a signing secret without a coordinated flag day. The previous secret keeps verifying for a grace period you choose, so in-flight deliveries and slow-moving customers do not break.
Embeddable Customer Portal
Drop the @hookbase/portal React components into your own app with a scoped portal token. Your customers add endpoints, pick subscriptions, and read delivery logs without ever seeing the Hookbase dashboard.
Operational Webhooks
Webhooks about your webhooks. Subscribe your own systems to message.exhausted, circuit_breaker.opened, circuit_breaker.closed, and endpoint.disabled so support and ops hear about a broken integration first.
Signatures Your Customers Already Know How to Verify
Hookbase signs every outbound delivery according to the open Standard Webhooks specification: an HMAC-SHA256 signature over the message id, timestamp, and payload, delivered in webhook-id, webhook-timestamp, and webhook-signature headers.
That matters for adoption: your customers verify with any spec-compliant library rather than installing a vendor SDK. It also means the signature format is not lock-in — Svix, the other major webhooks-as-a-service platform, is a co-author of the same open spec, so moving between providers does not force every one of your customers to rewrite their verification code.

Who Uses Webhooks as a Service
Common reasons teams stop building outbound webhook delivery themselves.
Ship Webhooks as a Product Feature
Your customers keep asking for webhooks and you keep deferring it because delivery, retries, signing, and a settings UI is a quarter of engineering work. Register an application per customer and send.
Replace a Homegrown Delivery Loop
A cron job looping over customer URLs works until the first slow endpoint blocks the queue. Move to managed delivery with per-endpoint circuit breakers, attempt history, and replay.
Give Customers Self-Serve Control
Stop handling endpoint URL changes and secret resets over email. Embed the portal in your own settings page and let customers manage their own endpoints and subscriptions.
Migrate off a Pricier Platform
Because both Hookbase and Svix emit the same open Standard Webhooks headers, your customers’ existing verification code keeps working when you switch — the signature format is not the lock-in.
