We are sending a date value to a date picker property in the form of YYYY-MM-DD (which we’ve confirmed with the app is ISO8601 compliant, but maybe that’s intrinsic of the date when written that way - don’t know what I’m talking about) we are getting this error: “validationResults”: [ { “isValid”: false, “message”: “2020-12-01 was not a valid long. Portal xxxxxxx, object type 0-3”, “error”: “INVALID\_LONG”, “name”: “invoice\_sent” } ], “status”: “error”, “message”: “Property values were not valid”, The Hubspot [documentation](https://developers.hubspot.com/docs/api/faq) says this: Examples: - 2015-05-01 would be used for May 1 2015 Not really a developer - any tips you can help me with? ---

Hey @JakeW You will want the date in the unix timestamp format as detailed [here](https://legacydocs.hubspot.com/docs/faq/how-should-timestamps-be-formatted-for-hubspots-apis) 😀 You are working your way up the ladder as a developer 😉 ---

Thanks @dennisedson - am I misreading the FAQ in this case then? One example given is in Unix as you’ve suggested, but it also lists a stock YYYY-MM-DD as an ‘example’ of how to send dates to a Date Picker property. Here’s a screenshot from [this article](https://developers.hubspot.com/docs/api/faq) I’m referring to ![34892iE9435643A6F9BDE6.png](https://d2qpr2jzcazej7.cloudfront.net/original/3X/0/7/07b0d4f42661bb0fbb0dfd7f8c62c4a05957952f.png) I’m only going the extra mile to ask here because our app doesn’t have an automatic means to reformat dates into a Unix timestamp ---

Hey @JakeW , Thanks for following up on that. Looks like we may have some contradictory messaging 🤔 Would you do me a favor and send me the endpoint that you are posting to (minus hapikey) as well as the json body? Here is a [post](https://community.hubspot.com/t5/APIs-Integrations/Update-Custom-Date-Picker-in-Deals-through-the-API/m-p/229501/highlight/true#M8397) with a similar issue as well as the [referenced docs](https://legacydocs.hubspot.com/docs/faq/how-should-timestamps-be-formatted-for-hubspots-apis) Once you send me the details I asked for, I will test and make sure we get some consistency 😀 ---

Thanks @dennisedson - the docs mention UNIX timestamp - I think we can do that through the app we’re trying to do this with. I don’t know how to determine what endpoint we are posting to, or what a hapikey and json body are, so I’m not sure I can help further o\_o For now I’ll just assume that we need to send it in UNIX in milliseconds, and it’s incorrect to say that date pickers can receive a straight up YYYY-MM-DD value … ---

I am running into the same issue with using unix timestamp as well and have asked this question multiple times via support but no answer.
