Institution list

After successful onboarding, you can integrate with Volt. The first step in creating the user experience is institution selection. The GET /institutions endpoint returns all the data needed to build an interface where the user selects the bank (institution) from which an account-to-account payment should be made.

Endpoint:

Required query parameters:

• currency – Payment currency (e.g., GBP, EUR)
• country – Country of the user initiating the payment (ISO 3166 alpha-2 format, e.g., GB, PL)

Optional parameter:

• active – Filter institutions by active status (true or false)

Many institutions require specific account data to be provided before the payment process can continue.

1. When calling GET /institutions, each institution has an accountIdentifiersRequired field, which is an array containing the names of account identifiers that must be provided.
2. Identifiers in the response are used in SNAKE_CASE format. For POST /payments, identifiers must be converted to camelCase.
3. In the POST /payments request body, required identifiers should be placed in the accountIdentifiers object, within the object corresponding to the given payment institution.
