What is Webhook?

Definition, examples, and more

Definition

An automated, real-time message sent from a system (e.g., Stripe, Botsi) to your backend when a subscription event occurs, such as a renewal, cancellation, or trial start. Webhooks enable immediate updates to user status and CRM sync.

Example

When a user starts a trial, Botsi sends a webhook to the app's backend containing user_id, event_type: 'trial_started', product_id, and timestamp. The backend updates the user's entitlements and triggers a Braze welcome campaign — all within 2 seconds of the purchase.

Why Webhook Matters

Webhooks are the connective tissue of modern subscription infrastructure. Without them, systems operate in silos — your CRM does not know about billing events, your backend has stale entitlements, and lifecycle campaigns fire too late. A fitness app integrated Botsi webhooks with their CRM and saw dunning campaign response rates improve 40% because messages now fired within minutes of a billing failure instead of hours.

Frequently Asked Questions

What subscription events should I listen for via webhooks?

Essential events: trial_started, subscription_purchased, subscription_renewed, subscription_canceled, payment_failed, refund_processed, and subscription_expired. Each should trigger an appropriate backend action and/or CRM campaign.

How do I handle webhook failures?

Implement retry logic: if your server does not return a 200 response, the webhook sender should retry (Botsi retries automatically). Log all incoming webhooks for debugging. Implement idempotency (handle duplicate deliveries gracefully). Set up monitoring to alert you if webhook processing fails.

Do I need webhooks if I use Botsi?

Botsi handles most subscription management internally, but webhooks let you sync events with your own backend, CRM, data warehouse, and other systems. They are optional for basic subscription management but essential for advanced lifecycle marketing and custom business logic.
