Version management

Version management

You can create multiple versions of a managed API, choose the default version, and delete a version.
When you create a version of a managed API, API Manager creates an additional managed API with the same name. Each version appears as a separate entry on the API Registry page. Default appears next to the entry of the default version on the API Registry page.
If a version of a managed API is not the default version, API Manager adds the version to the API URL of the managed API. API Manager doesn't add the version to the API URL of the default version.
API consumers can invoke all versions of a managed API with a URL that contains the version, including the default version. A URL that doesn't contain the version always invokes the default version.
In the API details window, the API URL of the default version doesn't include the version. If you choose a different version as the default version, API Manager adds the version to the API URL of the previously default version, and removes the version from the API URL of the current default version. Be sure to notify API consumers of the changes in API URLs.
When you create a new version of a managed API, you can choose whether or not API Manager applies the policies of the managed API version that the new version is based on to the new version. Policies include authentication method and API-specific policies. If you choose not to copy the policies from the original version, configure policies for the new version.
If you choose to copy the policies, and the original version uses JWT tokens, create JWT tokens for the new version. The tokens that the original version uses don't apply to the new version.
If a managed APIs has multiple versions, you can delete any version of the managed API other than the default version. To delete the default version of the managed API, choose a different version as the default version.
