A webhook is a web callback that Belvo uses to send notifications specific to a link.

How do webhooks work?

Belvo automatically refreshes recurrent links on a daily basis to retrieve fresh content. Once we refresh a link, we notify your application of any interesting events may occur. This can include information such as new transactions, link credentials have changed, and so on.

🚧

Webhooks only work with recurrent links. For more information on recurrent links and how they are refreshed, check out our Single vs Recurrent link documentation.

To start receiving webhook events, you need to set up a webhook URL.

Setup webhooks

To set up a new webhook:

1. In your Belvo dashboard, go to the Configuration section.
2. Select the Recurrent links tab and click New webhook.
3. Enter in the require information in the New webhook form.
   1. URL: the URL to receive the webhook notifications.
   2. Authorization: an optional bearer token to use if your URL is protected.
   3. Environment: in which environment to receive the webhook notifications. You can choose either Production or Sandbox.
4. Click Create webhook.

✳️ Done! The webhook is now setup and your application will be notified of new events related to your links.

Webhook retries

If Belvo does not receive a 2xx HTTP status code from an institution, the notification attempt is repeated five times using a linear backoff to allow the institution's server to recover from any malfunction.

Webhook events

📘

Webhooks in the Sandbox environment

At the moment our Sandbox environment does not support LINK webhook event types.

For all other webhook types, you will always get a historical event when you create a link in an institution. However, new events are only triggered when Belvo refreshes the link.

Below is a list of webhook types as well as the events that can be triggered depending.

Links webhooks

Invalid credentials

You can receive notifications via a webhook whenever credentials are not valid anymore to update a recurrent link. An example situation of this is when a user changes their bank credentials.

Payload example:

{
  "webhook_id": "aadf41a1fc8e4f79a49f7f04027ac999",
  "webhook_type": "LINK",
  "webhook_code": "invalid_credentials",
  "link_id": "16f68516-bcbc-4cf7-b815-c500d4204e28",
  "data": {
    "error_code": "login_error",
    "error_message": "Invalid credentials provided to login to the institution",
    "status": 400
  }
}

Once you receive this notification, you can ask your customer to update their new password using the Connect widget in update mode. As soon as the credentials are correct, the recurrent link is refreshed.

If you are not using the Connect widget, you can ask your customer to send you their new password and then perform a Link update call to save the new password. For example:

curl -X PUT https://api.belvo.co/api/links/{id} \
  -H 'Content-Type: application/json' \
  -H 'Host: api.belvo.co' \
  -H 'cache-control: no-cache' \
  -d '{
      "password": "newpassword"
  }' \
  -u [Secret Key ID]:[Secret Key PASSWORD]

Token required

You can receive notifications via a webhook whenever we need a new MFA token, requested by the institution, to keep the recurrent link working.

Payload example:

{
  "webhook_type": "LINK",
  "webhook_code": "token_required",
  "link_id": "30cb4806-6e00-48a4-91c9-ca55968576c8",
  "data": {
    "error_code": "token_required",
    "error_message": "MFA token was required by the institution",
    "status": 428,
    "session": "2675b703b9d4451f8d4861a3eee54449",
    "expiry": 9600,
    "token_generation_data": {
      "instructions": "Use this code to generate the token",
      "type": "numeric",
      "value": "12345"
    }
  }
}

Once you receive this notification, you can ask your customer to provide a new token using the Connect widget in update mode. As soon as the token is provided, the recurrent link is refreshed.

Accounts webhooks

New accounts available

You can receive notifications via a webhook whenever new accounts are available for a bank recurrent link.

Payload example:

{
  "webhook_id": "aadf41a1fc8e4f79a49f7f04027ac999",
  "webhook_type": "ACCOUNTS",
  "webhook_code": "new_accounts_available",
  "link_id": "16f68516-bcbc-4cf7-b815-c500d4204e28",
  "data": {
    "new_accounts": 1
  }
}

Once you receive the webhook notification, you can search the list of accounts to pull the details of these new accounts. For example:

curl https://api.belvo.co/api/accounts/?link=16f68516-bcbc-4cf7-b815-c500d4204e28 \
  -u [Secret Key ID]:[Secret Key PASSWORD]

Historical update

As soon as your banking recurrent link is created, we will asynchronously load the accounts available. You can receive notifications via a webhook whenever the account list is available for you to access.

Payload example:

{
  "webhook_id": "aadf41a1fc8e4f79a49f7f04027ac999",
  "webhook_type": "ACCOUNTS",
  "webhook_code": "historical_update",
  "link_id": "16f68516-bcbc-4cf7-b815-c500d4204e28",

  }
}

We define new_transactions as all new transactions found in the institution for this link.
It could be the new transactions from the last 24 hours but also new transactions added by the institution for previous days.
After creating a new recurrent link, all history of transactions will be pulled during the next refresh and the new_transactions will include all this initial history.

Once you receive the webhook notification, you can perform a search using the list of transactions to pull instantly the details of those new transactions. For example:

curl --request GET 'https://api.belvo.co/api/transactions/?link=16f68516-bcbc-4cf7-b815-c500d4204e28&collected_at__range=2020-01-01,2020-01-02' \
