Adding or Deleting Image Tags in Batches

Function

This API is used to add tags to, update tags of, or delete tags from an image in batches.

Constraints

  • Each tag consists of a key and a value. The key contains at most 36 characters, and the value contains at most 43 characters. The key cannot be left blank or an empty character string. The value cannot be left blank but can be an empty character string.
  • An image can have a maximum of 10 tags.
  • The keys of multiple tags in the request body must be unique.
  • This API is an idempotent one.

    If a tag to be added has the same key as an existing tag, but the tag values are different, this tag will be added and overwrite the existing one. If a tag to be added has the same key and value as an existing tag, this tag will not be added.

    If the specified tag does not exist, the deletion is considered successful by default.

  • Restrictions on tag keys and values during batch deletion

    During the deletion, the system will not verify the character set range of the key and value. The key cannot be left blank or an empty character string. The value is optional and will not be not verified. If the tag to be deleted does not exist, the deletion is considered successful and no error is reported. Also, the system will not verify the length of both the key and value. The key can contain a maximum of 127 characters, and the value contains a maximum of 255 characters.
