Question Nexus update key

[Quirinea]

Well. Earlier Nexus gave automatically an update key to a mod, but now it seems it doesn't. And I got no answer asking them how it is generated (or if I can put myself in a random number).
Search in their documentation gave no information (it was clogged by e.g. Steam keys) .
?????
(I'm trying to look at my own mods: ones dated 7/20 DO have a key (and I know for sure I've not myself put in random four-digit numbers), 8/20: no number.

When posting a mod on NexusMods, there should be a three or four digit number up in the website address after https://www.nexusmods.com/stardewvalley/mods/ and that is the update key. You can't access it until after a mod is posted.

OK, the obvious answer that is nowhere stated. I may have heard it earlier, but forgotten the information. Thanks!
