What is a webhook?
Creem uses webhooks to push real-time notifications to you about your payments and subscriptions. All webhooks use HTTPS and deliver a JSON payload that can be used by your application. You can use webhook feeds to do things like:- Automatically enable access to a user after a successful payment
- Automatically remove access to a user after a canceled subscription
- Confirm that a payment has been received by the same customer that initiated it.
Steps to receive a webhook
You can start receiving real-time events in your app using the steps:- Create a local endpoint to receive requests
- Register your development webhook endpoint on the Developers tab of the Creem dashboard
- Test that your webhook endpoint is working properly using the test environment
- Deploy your webhook endpoint to production
- Register your production webhook endpoint on Creem live dashboard
On Next.js projects, the
@creem_io/nextjs adaptor exports a
Webhook
helper that verifies signatures and surfaces typed lifecycle callbacks. Use it
as your default implementation before falling back to manual parsing.1. Create a local endpoint to receive requests
In your local application, create a new route that can accept POST requests.2. Register your development webhook endpoint
Register your publicly accessible HTTPS URL in the Creem dashboard.
3. Test that your webhook endpoint is working properly
Create a few test payments to check that your webhook endpoint is receiving the events.4. Deploy your webhook endpoint
After you’re done testing, deploy your webhook endpoint to production.5. Register your production webhook endpoint
Once your webhook endpoint is deployed to production, you can register it in the Creem dashboard.Webhook Signatures
How to verify Creem signature?
Creem signature is sent in thecreem-signature header of the webhook request. The signature is generated using the HMAC-SHA256 algorithm with the webhook secret as the key, and the request payload as the message.
Sample Webhook Header
Sample Webhook Header
To generate the signature, you can use the following code snippet:
payload is the request body, and the secret is the webhook secret.
Simply compare the generated Signature with the one received on the header to complete the verification process.
