How to set Date via API

Question

I've gone through a 100 posts about date but can't work this out.

When i GET from the API the date is in format 2021-12-01 but it doesn't accept it when using POST.

Anyone know what format it should be in? It's a date field not datetime

It was late and I am dumb.. I forgot to convert it to string.

$( Get-Date $($LeaseInfo.'Start Date') -Format 'yyyy-MM-dd' ).ToString()

Hi,

As noted in the documentation, for a Date picker custom field this should be something like that:

"customfield_11441" : "2015-11-18"

For a date system field

"duedate" : "2015-11-18"

Can you share your code please and the error message.
