How to validate Vimeo video id?

I need to create a regular expression which could validate a valid Vimeo video.

Accordingly to Vimeo API they use only numbers for Video Id, but they do not specify the length.

My regular expression so far var regEx= /^[0-9]+$/;

I would like to know: - What is the allowed length supported by vimeo video id? - How to modify my regEx?

Only article I found: https://vimeo.com/forums/topic:267078

Solution

Instead of trying to invent a Vimeo Video ID validator, why don't you just use the Vimeo developper API to check if the Vimeo ID is valid?

GET https://api.vimeo.com/videos/{video_id}

+------------------+--------------------------------------------------+
| 403              | if the video does exist, but the view or the app |
|                  | requesting the video resource does not have      |
|                  | permission to access that video.                 |
+------------------+--------------------------------------------------+
| 404 not found    | If the video cannot be found.                    |

Check if you (1) or a user (2) owns a video:

(1) GET https://api.vimeo.com/me/videos/{video_id}
(2) GET https://api.vimeo.com/users/{user_id}/videos/{video_id}

+------------------+------------------------------------------------------+
| 404 not found    | If the video is not owned by the authenticated user. |
