Build against a clear contract before production.
The developer suite separates the production contract from a deterministic browser sandbox. Every API operation has its own implementation page with request shape, response fixture, failure handling, code samples and runnable tests. Sandbox requests use generated test data only and never reach member records, banking providers or production financial execution.
Production OpenAPI
Routes, scopes, security and production capability state come from the accepted public v1 specification.
Download OpenAPI JSONDeterministic sandbox
Predictable customer IDs, institutions, balances, transfers and errors for repeatable integration tests. No live calls.
Run sandbox testsDeveloper contact
Include request IDs and UTC timestamps. Do not email full API secrets or customer KYC documents.
[email protected]Integration sequence
Read the contract
Review authentication, scopes, idempotency, money units and errors before writing request code.
Exercise sandbox
Validate request construction and failure handling against generated fixtures.
Request approval
Production credentials are application scoped and capability controlled.
Observe and reconcile
Persist request IDs and idempotency keys. Do not blindly repeat consequential writes.
API reference
30 HTTP operations are documented in the current public v1 contract. Conditional routes remain clearly marked. A successful sandbox simulation does not mean the production capability is enabled.
