Adding "@username" format

Substack changed the default presentation of user profiles to show the "@username" in the URL instead of the numeric id. The numeric ID can still be found with more technical means probably, in for ease of use extending the regex to allow for both seemed like the most simple solution. Kristbaum (talk) 22:00, 14 September 2023 (UTC)

I would also like to see this addresses.

Unfortunately the URL formats are different for handles vs IDs.

For example: @billwillingham doesn't work in the profile url https://substack.com/profile/@billwillingham

I wonder if we can follow what we do for YouTube where some bot takes the channel name and converts it to channel ID. https://www.wikidata.org/wiki/Property:P2397 RayScript (talk) 09:03, 15 September 2023 (UTC)

Unfortunatelly now any items using '@username' style IDs don't work with this property. Perhaps splitting into two properties, like YouTube's YouTube channel ID (P2397) and YouTube handle (P11245), is in order. Trivialist (talk) 02:24, 21 September 2023 (UTC)

Or this can be solved by allowing both syntaxes (distinguishable by the format) and choosing the proper destination URL in a linking helper (cf. e.g. https://wikidata-externalid-url.toolforge.org). --Mormegil (talk) 15:42, 22 September 2023 (UTC)

In the meantime, how do you find the numeric ID? Profiles URLs that I see are in the form https://substack.com/@profile and I have no idea how to get the equivalent https://substack.com/profile/123 format? Nclm (talk) 10:43, 27 April 2024 (UTC)

Just open Network Monitor in Firefox DevTools and just paste status-code:200 into the Filter URLs thingy.

and you will find the https://substack.com/api/v1/profile/posts?profile_user_id=546815&offset=0&limit=13 come up in the search result

I hope this helped you

(Also Wikidata for Web (Q99894727) this is awesome tool, but that dose not work for finding that ID maybe it should be programed for finding that id thingy?) Johshh (talk) 06:03, 25 August 2024 (UTC)

Also, for us poor clumsy non-robot humans, in addition to the difficulty in locating the numeric id, any property that requires one to insert the "@" symbol before a handle is very poor form. X username (P2002), Instagram username (P2003), YouTube handle (P11245) and probably most other social media identifier properties do not require it. This property is an outlier in addition to a mess. -Animalparty (talk) 01:40, 1 September 2024 (UTC)
