This page tracks notable changes to the Fincore API and its documentation: contract updates, behavior changes, new features, deprecations, and operational policies (e.g., webhook delivery/retry rules).
Rule of thumb: if an integrator might need to adjust code, business logic, monitoring, or expectations, it belongs here.
Each release may include:
- Type: Added / Changed / Deprecated / Removed / Fixed / Security
- Tags (impact):
- [Breaking] — requires changes to avoid failures.
- [Behavior] — not necessarily breaking, but outcomes or rules changed.
- [Operational] — affects retries, delivery, latency, or runtime expectations.
- [Docs] — documentation-only changes (no functional change).
- [Security] — security-related change.
For every entry we aim to include:
- Impact: what changes for you
- Action required: what you should do (if anything)
- References: links to the relevant guide/endpoint
