GoCardless Bank Account Data vs InterPay + DDMS

GoCardless Bank Account Data is an API for businesses that need account details and transaction data from connected bank accounts. It connects through bank PSD2 APIs and can return account holder names, account identifiers, IBANs, transaction dates, counterparties, descriptions and amounts, plus current and available balances. It can retrieve up to 24 months of transaction history, with continuous access lasting up to 90 days. Data refreshes on demand, and responses use JSON. To connect, an end user chooses a supported financial institution, accepts a GoCardless-hosted consent screen and authenticates through the institution. API requests use an authorization token created with a Bank Account Data portal user secret. GoCardless provides a quickstart guide and instructions for importing the API schema into Postman. Availability is limited to EEA countries subject to PSD2 where GoCardless operates as an authorized AISP. Banks may restrict requests to as few as four calls per account per day. Account verification is available only to paying customers; new accounts are unverified by default. The service is paid, with pricing on request, and is available via API and web.

InterPay + DDMS is a web-based system for managing Direct Debit collections and submitting them through InterPay. DDMS lets businesses create, edit, and cancel Direct Debits, manage regular credits, and send automated notification emails. It checks bank account data against Bacs rules to help preserve collection eligibility. InterPay Web DDMS provides downloadable Bacs reports in actionable formats. InterPay can retrieve ADDACS and AWACS reports, apply selected actions, update DDMS bank details, and initiate relevant emails or letters. The two products work together so collection management and submission take place in one system. Interbacs can provide secure online sign-up pages connected to DDMS, with collection data passed to an accounts package through an API. An optional HSM workflow stores submission keys and certificates on a FIPS 140-2 Level 3 compliant device. Interbacs says its software gained Bacs accreditation in 2010. Pricing is on request.
