Adyen sends webhooks to inform your system about events that occur in your balance platform. These events include when a card user makes a payment with their Adyen-issued card, or when a merchant starts a refund.<\/p>\n
When an event occurs, Adyen makes an HTTP POST request to a URL on your server and includes the details of the event in the request body.<\/p>\n
You can use these webhooks to build your implementation, for example, to update balances in your own dashboards or keep track of incoming funds.<\/p>\n

When you have an endpoint ready, you can configure and subscribe to webhooks in your Customer Area<\/a>. To do this, your user account must have the Merchant admin<\/strong> or Merchant technical integrator<\/strong> role. For more information, see the user roles<\/a>.<\/p>\n To configure webhooks:<\/p>\n You can configure webhooks only via your Customer Area<\/a>. When you are already receiving webhooks, make sure you accept each one<\/a>.<\/p>\n If you are processing payments with Adyen and want to reuse an existing endpoint, make sure the endpoint can handle the Balance Platform webhook structure<\/a>. This differs from Adyen's standard webhooks<\/a>.<\/p>\n<\/div>\n Adyen signs every webhook with an HMAC signature in the request header. You can verify the HMAC signature to add an extra layer of security. By verifying this signature, you'll confirm that the webhook was sent by Adyen and was not modified during transmission.<\/p>\n For every webhook that you receive, get the values from the following headers:<\/p>\n Calculate the signature using:<\/p>\n Then base64-encode the result.<\/p>\n<\/li>\n Compare the Here are some examples of how you to validate the HMAC signature.<\/p>\n To ensure that your server is properly accepting webhooks, we require you to acknowledge every webhook event with a successful HTTP response status code<\/a>, such as 202<\/strong>. If we do not receive this response within 10 seconds, for example because your server is down, all webhook events to your endpoint go to the retry queue<\/a>.<\/p>\n When your server receives a webhook:<\/p>\n\n
