HappyFox allows users to set dynamic dropdown values for ticket custom fields. These dropdown values will be maintained in an external source and will be fetched and displayed into the respective ticket custom field. Any additions/deletions/modifications done to the values will be reflected accordingly.

This is achieved using the HappyFox API as follows:

API Endpoint: api/1.1/json/ticket_custom_field/<ticket_custom_field_id>/

Method: PUT

Query parameters that can be passed to the url are listed below with their description

Note: Only choices property of ticket custom field can be updated with V1 API

Example Payload

Let's consider the following case for updating the ticket custom fields choices

• “Option 1” - no change

• “Option 2 (Edited)” - edited

• “Option 3” - existing option that need to be deleted 

• “Option 4” - new option

Note: “Option 3” which is to be deleted is not present in the below payload

{
    "choices": [
            {
                "id": 11,
                "text": "Option 1",
                "dependant_fields": []


            },
            {
                "id": 12,
                "text": "Option 2 (Edited)",
                "dependant_fields": []
            },
            {

                "text": "Options 4",
