Assuming your existing Deal property “d_tools_project” already is type “enumeration” and fieldType “select”, all you’ll need to supply in the update property API call are the valid value options. Here’s the relevant HubSpot API documentation. For example:
PATCH https://api.hubapi.com/crm/v3/properties/:OBJECT\_TYPE/:PROPERTY\_NAME
e.g. PATCH
https://api.hubapi.com/crm/v3/properties/deal/d\_tools\_project
Example Request JSON body
{
"options": [
{
"label": "Option A",
"value": "A",
"hidden": false, // optional
"description": "Choice number one", // optional
"displayOrder": 1 // optional
},
{
"label": "Option B",
"value": "B",
"hidden": false, // optional
"description": "Choice number two", // optional
"displayOrder": 2 // optional
}
]
}
I hope that proves helpful. Please let me know if you have any follow-up questions.
