Using the Belvo API, you have the possibility to register two types of links:
Single links are used to perform ad hoc data access to accounts, owners and transactions.
For single links you will have to perform POST calls to retrieve
transactions every time you want to access fresh data from the institution.
With recurrent links, Belvo automatically accesses information on a daily basis so you always have fresh and updated accounts, owners and transactions data.
Every day we automatically connect to the institution to retrieve:
- the accounts information for the link, including the live balance and credit data
- the new transactions added during the last 365 days
- the owners information for the link
Then, using the List/Detail endpoints of the
owners you can instantly access up to date information, without needing to connect to the institution.
You can read more about the difference between single-use and recurrent links in our developer portal.
