v1.6.4

Happy start of summer from the ModernFi team! See below for our latest API changes.

This release adds account status filtering, OAuth-authenticated PDF statement downloads, and a refinement to account updates. We recommend reviewing this page closely before beginning development or upgrading to a new API version.

Updated Endpoints

  • GET /digital-banking/v1/accounts (List Accounts)

    • Added statuses query parameter (AccountStatus array, optional, repeatable) — filter accounts by status, e.g. ?statuses=OPEN&statuses=SCHEDULED_FOR_CLOSURE. If omitted, accounts of all statuses are returned.

  • GET /digital-banking/v1/files/{file_id} (Get File)

    • Added response_type query parameter (FileResponseType, optional, default presigned_url). The default returns a JSON pre-signed download URL exactly as before. Pass response_type=file to stream the file back directly as raw bytes, with the Content-Type derived from the file (e.g. application/pdf or text/csv) — useful for environments that cannot fetch AWS pre-signed URLs. This powers OAuth-authenticated PDF statement downloads without a separate pre-signed-URL round trip.

  • PATCH /digital-banking/v1/accounts/{account_id} (Update Account)

    • Removed account_type — account type can no longer be changed after creation.

Schema Changes

  • New enums
    • AccountStatus — OPEN, SCHEDULED_FOR_CLOSURE, CLOSED
    • FileResponseType — presigned_url, file
