The current version is: `2026-03-30` API versions are specified using the `Method-Version` header, and while you may continue using older versions, you will not have access to the latest features. You can upgrade to the latest or a specific version through the [Dashboard](https://dashboard.methodfi.com), or by specifying the version in request headers. Note that once upgraded manually, it's not possible to revert to older versions. #### Backwards Compatible Changes Method defines the following changes as backwards-compatible: * Adding new API resources. * Adding new properties to existing API responses. * Adding new values to enum fields in API responses. * Adding new properties to webhook payloads. * Changes to the length, format, or content of human-readable strings (error messages, etc.). * Adding new event types. * Make sure that your webhook logic can gracefully handle unfamiliar event types. #### Library Versioning For Method Libraries, the version is locked to the dated version of the API. * `method-node v0.x.x` and `method-python v0.x.x` are locked to `2020-12-06` * `method-node v1.x.x` and `method-python v1.x.x` are locked to `2024-04-04` * `method-node v2.0.x` and `method-python v2.0.x` are locked to `2025-07-04` * `method-node v2.1.0+` and `method-python v2.1.0+` are locked to `2025-12-01` Use the version dropdown in the navigation bar to view documentation for your API version.
