How Deprecation Works

When a product, feature, API endpoint is deprecated it begins on the deprecation notice date. The functionality is then considered Deprecated during a deprecation grace period, until it is effectively Decomissioned (removed).

📘 Key term: Deprecated means a feature, API endpoint, behaviour etc is still available but should no longer be used. Reasons may include:

• A better alternative exists, e.g. a new API endpoint.
• The functionality is about to be decommissioned (removed).

📘 Key term: Decomissioned means a feature, API endpoint, a field in a API request/response structure etc is no longer supported and may have been removed. Calling such an endpoint, or relying on deprecated properties in API responses may led to unpredictable behaviour.
