API Changelog

BankConnector's HTTP API is versioned by date, via the BankConnector-Version header — not by URL path or a v1/v2 prefix. Pin a version and it behaves consistently for you even as the platform evolves underneath it:

BankConnector-Version: 2026-06-01

Every response echoes back the version it was served under (including error responses), so you can confirm what you're pinned to at a glance. Omit the header and you get the current baseline behaviour.

How to read this page

Entries below are integrator-facing contract changes only — new fields, behaviour changes, deprecations. This is not the engineering changelog (internal refactors, security hardening, and infrastructure work that don't change the contract aren't listed here).

2026-06-01 — baseline

The current baseline version. Canonical input schema 1.1 (additive over 1.0: structured postalAddress, regulatoryReporting, and purposeCode / localInstrument / categoryPurpose overrides — see Core Concepts). Object error envelope ({ error: { code, message, details? } }) is current.

Nothing has shipped a breaking contract change since the baseline. This page will grow as the API evolves — watch it if you pin a specific BankConnector-Version.
