Sandbox

List sandbox-eligible test banks

Returns the canonical sandbox FIXTURE catalog (ins_sandbox_001 / ins_sandbox_002) for synthetic flows.

NOTE: real sandbox bank routing uses the standard /v3/institutions catalog; ins_0a01a5430925d0b2 (FinBank M, Finicity sandbox) and ins_eaee71edf17fdacd (MX Bank, MX sandbox) live there. This endpoint exists for backward-compat with early sandbox readers.

Drive the widget end-to-end with the public test bank credentials documented in the developer portal’s testing playbook (customer1 / go for Finicity, mxuser / correct for MX).

Calling this with a live key returns 403.
