Integration principle

A successful Open Finance integration is more than an API response. The contract must keep customer permission, institution policy, data quality, action status, observability, and exception handling visible across the journey.

Illustrative flow

One consent bound request from authorization to usable signal.

The example shows the shape of a FINX integration without publishing production paths or pretending a public sandbox is available before access is approved.

Short lived credentials and scoped access
Purpose bound consent references
Idempotency and correlation identifiers
Explicit success, pending, and failure states

Illustrative request

POST /v1/financial-data/requests
Authorization: Bearer <access_token>
Idempotency-Key: <unique_key>

{
  "consent_id": "consent_reference",
  "data_scope": ["accounts", "transactions"],
  "customer_context": "institution_reference"
}
