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.
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.
Support pagination. If there is next_marker in the response, more output is available than is included in the current response. Use this value in the marker request parameter in a subsequent call to get the next part of the outputs. You should repeat this until the next_marker response is set to null.

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