Error when posting to multiple checkbox contact field via Contacts API

[IParsons]

I'm getting a validation error when posting values to a multiple checkbox field using the Contacts API.

This is the code I'm using to post: 

array(
                'property' => 'allteamguids',
                'value' => str_replace(',', ';', $allTeamGUID)
            )

Here is the response I get from the API: 

{"validationResults":[{"isValid":false,"message":"28287d04-9ca8-4aa2-ad82-853248fd58e6 was not one of the allowed options: [label: \"0035139a-bc65-4fc0-bca4-371631034395\"\nvalue: \"0035139a-bc65-4fc0-bca4-371631034395\"\n, label: \"02084cca-b689-42d6-85c4-47fd83d2dca2\"\nvalue: \"02084cca-b689-42d6-85c4-47fd83d2dca2\"\n, label: \"02a1843a-5b85-4ee1-ac27-7a956d8c3980\"\nvalue: \"02a1843a-5b85-4ee1-ac27-7a956d8c3980\"\n, label: \"05078554-f6dc-443e-8921-000dc95e7b58\"\nvalue: \"05078554-f6dc-443e

Hi @IParsons 

Can you confirm that that value exists in the possible property values?

Hi @dennisedson - thanks for your reply. 

These values don't exist as property values - I assumed the API would create them as options if they don't exist, but I realise now that's quite a big assumption 🙂 

I'll go do some research, but please let me know if it's possible to create additional values through the API?

You can patch the property with aptly named Properties API 😀

Test it out.  I believe you need to have all of the available values in your call when updating.  So if you sent a request with just the new value, it would remove all of the others and only have the one new value.  (I could be wrong, it has been a bit since I tested it)
