Get a High-priority push notification when a Mollie payment fails, including the card's decline reason when there is one.
Three steps to your first push
STEP 01
Install the recipe
One click in Studio gives you a personal webhook URL.
STEP 02
Paste your URL into Mollie
Add it as a webhook for payment.failed.
STEP 03

With the text, sound and buttons from the recipe.
How to set up the Mollie payment.failed webhook
- Click Install in Studio and sign in. The recipe is added to your account and you get a personal webhook URL.
- In the Mollie Dashboard, go to Developers > Webhooks and create a new webhook.
- Paste your webhook URL as the URL and select the payment.failed event.https://••••••••/•••••••• your personal URL, shown after install
- Choose the full payload (so the payment details are included) and save.
- This recipe needs a **next-gen** webhook (Developers > Webhooks), set to send the **full payload**. Classic webhooks (the `webhookUrl` you pass when creating a payment) only send the payment ID, so they can't produce a useful notification.
- Mollie signs next-gen webhooks with an `X-Mollie-Signature` header, but JustPush doesn't check it yet, so keep your endpoint URL private.
What runs when the webhook arrives
Studio calls handleRequest(request) with the incoming webhook and sends the message it returns. It's yours after install; change anything.
