Grow CRM Webhooks notifies your own server in real time whenever something happens in the CRM — an invoice is created, a lead converts, a payment comes in. You provide a destination URL and choose the events you care about; when those events occur, the CRM sends an HTTP POST request carrying a structured JSON payload. The Webhooks module is self-contained and does not require the API module to be installed.

​
Where to manage webhooks

Navigate to Settings → Webhooks → Endpoints to manage all your webhook configuration. Each entry you create there is called an endpoint — a destination URL paired with a set of subscribed events. You can create as many endpoints as you need, and each one can subscribe to a different set of events.

​
How delivery works

Delivery is asynchronous: creating an invoice, for example, is never slowed down by a webhook receiver being temporarily unavailable. Follow the steps below to understand exactly what happens between an event firing and your server receiving the payload.
1

Event is queued

When a subscribed event fires in the CRM, the system creates one delivery row per active, subscribed endpoint. Each delivery is independent.
2

Background process sends the delivery

A background process runs every minute and dispatches all due deliveries. Your server receives an HTTP POST with a JSON body.
3

Your server acknowledges

Respond with any 2xx status code to mark the delivery as successful. Requests time out after 15 seconds; anything other than a 2xx — including a timeout — counts as a failure and triggers a retry.
4

Do slow work after responding

Acknowledge the delivery immediately and then process it asynchronously. A receiver that performs slow work before replying risks tripping the 15-second timeout, which causes a duplicate delivery on the next retry attempt.

​
The payload envelope

Every delivery is a JSON object with the same four top-level fields regardless of which event fired or which resource it relates to.

​
Retry schedule

A failed delivery is retried up to two more times before being marked Exhausted. The three attempts follow this schedule:

​
Auto-disable behaviour

If an endpoint accumulates 10 consecutive exhausted deliveries with no successful delivery in between, Grow CRM automatically disables the endpoint and emails the CRM’s main administrator. A disabled endpoint stops receiving new deliveries entirely until you re-enable it.
To re-enable a disabled endpoint, fix the underlying issue on your receiving server, then open the endpoint in Settings → Webhooks → Endpoints, and save it again. Saving reactivates the endpoint and new deliveries will resume immediately.

Next steps

Endpoints

Create endpoints, subscribe to events, send test deliveries, and inspect the delivery log.

Verification

Validate every incoming request so you only process payloads that genuinely came from Grow CRM.
