Server-to-Server Webhooks

📘
Note
Server-to-server webhooks is a premium feature and available on Launch and Grow plans.

Apphud's webhook system for subscriptions allows you to catch the moment when a subscription event occurs. You can use this data to implement custom logic or analytics on your own server. You simply need to specify a URL for POST-request.

Webhooks are being sent as POST request to specified URL.

How to Add Webhook?

Step 1

At Apphud go to the "Integrations" section, click S2S webhooks add click New webhook:

Step 2

Enter webhook name and specify webhook URL. Events will be sent to this URL using POST-request:

Step 3

You may optionally specify Secret token that will be sent with the webhook request in the X-Apphud-Token HTTP header. Use this token to validate received payloads.

Step 4

Choose which between Production and Sandbox events to be sent via webhook:

Step 5

Enable events which you would like to receive webhooks for:

Step 6

Enable and save the integration:

❗️
Important Note
Apphud sends only one request per webhook without retries.

Step 2

Copy Endpoint URL:

Step 3

Create new Webhook in Apphud using this URL. Make sure you selected "Sandbox" environment while configuring webhook.
