What format does the date for a date picker field need to be when submitted through the API

Hello i am trying to add a submission to a form through your API.

But i cannot find any documentation for how the date should be formatted when sending the submission through the API

i have tried several common ones but the field continues to be empty in all my submissions

Any guidance would be appreciated

Based on some tests, the format depends on how the Date field in your form is set up.

With this setup:

Dash Separator

Litemode; MM-DD-YYYY format;

Here's the result:

But with this setup:

Slash Separator

Disabled Litemode; YYYY-MM-DD format;

Enabled Time Field;

Here's the result:

I hope this helps. Feel free to let us know if you need any further assistance. Also, if you are looking for the submission date format, notice that it didn't change for both my test submissions.
