Listing Template Versions

Function

ListTemplateVersions

This API lists all template versions in a template.

By default, the template versions are sorted by creation time. The template created latest is displayed on the top.
Currently, all template versions are returned. Pagination is not supported.
If there is no template version, an empty list will be returned.
template_id is the unique ID of the template. It is a UUID generated by RFS when a template is created. Template names are unique at one specific time, so you can create a template named HelloWorld and another template with the same name after deleting the first one. For parallel development, team members may want to ensure that they are operating the template they created, not one with the same name created by other members after deleting the previous one. To avoid this mismatch, check the ID, since RFS ensures each template has a unique ID that does not change with updates. If the template_id value differs from the current template ID, 400 is returned.
If the template does not exist, 404 is returned.

ListTemplateVersions returns only summaries of template versions. For details, refer to ListTemplateVersionsResponseBody. To obtain the template version, call ShowTemplateVersionContent.
