Update list giving 404 despite being accessible?

I’m trying to update the name of a list. When I do:
https://api.trello.com/1/lists/[listID]
with params:
name=11/29/21&key=[key]&token=[token]

I get a 404. But when I go:
https://api.trello.com/1/lists/[listID]/cards?key=[key]&token=[token]

It correctly returns the JSON. The key and token work fine, and the listID matches between the two calls. Am I formatting the update correctly, or have I missed something?

Hi and welcome!

You have the correct format and url. Are you sure you’re using a PUT when trying to update the list name? Have you tried it in something like Insomnia or Postman?

Your example works for me in Insomnia.

You’re right, that’s the problem. I was doing a POST and not a PUT. I knew it had to be something simple! Thank you :slight_smile:
