Value of the custom field. If custom field type is date, you can pass date string as a value. Please pass date with time in ISO 8601 format. We pass date with time in order to avoid next bug When we send API request with date "2023-06-26" from Chicago, IL (GMT-5). In DB value will be saved as UTC date "2023-06-26T00:00:00.000Z" But when we display it on the client UI we convert UTC date to user local timezone (subtract 5 hours) and get "2023-06-25T19:00:00-0500" (previous day) Exists several ways to fix it. 1. Pass date with timezone "2023-06-26T00:00:00-0500" 2. Pass data in UTC but with time shifted by negative GTM offset "2023-06-26T05:00:00Z" You could shift time more than GTM offset. For example add 12 hours for Chicago instead of 5 "2023-06-26T12:00:00Z"
