When backward-incompatible changes are made to the API, the version number is incremented with the new release. The API version is indicated in each endpoint resource path. For example, <https://api-sandbox.happymoney.com/v1/offers> indicates the API is at version 1. Minor updates and bug fixes are typically released without incrementing the version number. Ensure that your application gracefully handles API revisions by allowing for additional, unspecified resource fields in the response and for variable response sizes.
