Signed webhooks
Reviewed on 5 October 2026
On this page
A webhook tells another application as soon as something happens in your store, such as a sale, a refund or a cancelled subscription. Each notice is signed so the destination can check that it comes from OnBio.
Register a webhook
- 1. In Integrations, click New webhook.
- 2. Paste in Address the one the other application gives you.
- 3. Choose the Events you want to receive and click Save.
- 4. Copy the signing secret and save it in the destination.
Test the destination
- 1. Click See deliveries on the webhook's row.
- 2. Click Send test event.
- 3. Check under Deliveries that the test appears as Delivered.
What happens next
Each event arrives within seconds with its signature. If the destination does not answer, OnBio retries up to 8 times with growing waits. If all of them fail, the delivery stays as Undelivered and you can resend it.
Keep in mind
- The address has to start with https://.
- The secret is only shown when the webhook is created. If you lose it, click Rotate secret and put the new one in the destination.
- The code to verify the signature is in the developer reference.
- You can have up to 20 webhooks per store.
- If the webhook is turned off after many failures, follow webhook turned off.
