Breaking Changes in EAPI v1.0.5

🚨
Breaking Change — biller.bin Now Required

From EAPI v1.0.5, the biller.bin field is required on all bill payment requests (POST /transactions/billpayments). Requests missing biller.bin will return 400 Bad Request. Update all existing bill payment integrations before upgrading to v1.0.5.

v1.0.5 Change Details

EndpointFieldChangeAction Required
POST /transactions/billpayments biller.bin Breaking Changed from optional to required Add biller.bin to all bill payment requests

Notable Response Structure Notes

These are documented behavioral differences to be aware of when integrating:

EndpointFieldBehavior
POST /transactions/transfers balances Returns an object with two sub-arrays (paymentInstrument[] and beneficiaryInstrument[]) — not a flat array like other financial endpoints
POST /preferences/delete Operation Idempotent — returns success even if the profile does not exist. Uses POST (not HTTP DELETE) for channel adapter compatibility.
All financial endpoints balances[] Returns array of balance types: Available, Balance, and PaymentDue. PaymentDue includes a dueDate field for loan accounts.

Deprecated Fields and Endpoints

No fields or endpoints are currently deprecated in EAPI v1.0.5.
