How does Belvo work?

Once you implement Belvo, your users can connect their bank, fiscal, or employment institutions to your app in just seconds. After your users connect their accounts, Belvo will asynchronously retrieve the information and notify you using webhooks once the information is retrieved.

To create this connection, your users need to share their online credentials with Belvo. We encrypt these credentials as we receive them and only use them to access the account in read-only mode.

Once the Link is created between your app and your user's institution account, Belvo asynchronously retrieves the financial data and notifies you when it is available to retrieve. This includes the accounts in their name, the real-time balance, transaction information, invoices, and so on.

Example integration flow


A sample banking flow with Belvo

A standard banking integration flow with Belvo looks like this:

  1. Register a link using the Connect Widget
    Your end user connects to their account using our Connect Widget. After they've successfully connected, you'll receive a Link ID that you'll need to use in order to make further requests about the end user.
  2. Wait for historical webhook event
    As soon as your user connects their account, Belvo retrieves historical data about the user and sends a webhook once the information is loaded. Once you receive the webhook, you can make a GET request to the appropriate endpoint to retrieve the information.
  3. Receive update webhook
    Depending on the recurrent link update frequency you set, Belvo retrieves updated information and sends a webhook indicating new information is available for the link. When you receive the webhook, just send a GET request to the appropriate endpoint.

Data persistence

As soon as you register a link, you will not have to do it again. If you need to retrieve data about the link itself, you can use our List all links or Get a link’s details requests.

As soon as the data from the institution is asynchronously retrieved, you can access it directly through the List and Detail methods for the given resource.

Finally, you can delete any data from Belvo by calling the Delete method on the given resource.


Note: Deleting a link will also delete all the related resource information (such as accounts, transactions, and owners) associated with that link. Additionally, deleting an account will also delete all the transactions related to that account.

HTTP Methods

All our endpoints are associated with an HTTP Method with the following standard:

GETAccess data from Belvo.
POSTConnect to the institution to register or retrieve data. Retrieved data can be stored by Belvo so that you can access it in the future.
PATCHResume a previous connection request (POST) to the institution to add a 2FA token.
DELETEDelete data from Belvo.

Error handling


Save the request_id!

Make sure that when you receive an error you log the request_id. This will allow Belvo to debug the issue more swiftly and get back up and running as quickly as possible.

Errors are annoying - we know. That's why we have dedicated articles for each error in our DevPortal to help you solve them. Have a look at our API and Widget errors page, or just search for the error code you are encountering to go straight to the causes as well as solutions.
