# How are API versioning and API updates handeled? Generally, we try to have the **latest version on APIs** e.g. /v4/ Once a /v5/ is released, with grace period of 60 days, and users want to use it immediately, they can overwrite the base-domain in the [ConnectorAuth](/connectors/authentication/setting-up-authentication.md). If an old API version is still available and there is no immediate need, we will introduce a **new API version upon request** by customers with 48h notice by customers. Next, we will inform all customers about the upgrade to /v5/ and any potential breaking changes. Additionally, we **ask customers to move their connectors to the new version**. Once we see there is either no negative interference or all customers upgraded, we change our primary connector version to /v5/ . If a change only concerns individual endpoints, we either **inform customers and make the change immediately**, e.g. if the API just changed **without notice** and is unusable otherwise, or create a separate action with the new endpoint details and run both in parallel for some time, until all customer's flows are migrated. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
