GET Values from a custom field via JIRA REST API

Question

I would like to GET all drop down options for a custom field. For system fields, I use the following URI:

http://localhost:8080/rest/api/2/project/XXXX/components

(for components, versons, etc. Basically system fields), so I tried the following for a custom field

http://localhost:8080/rest/api/2/project/XXXX/customfield_10000

and got a 404 error. I'm not sure what I'm doing wrong as I've been googling for the past 19 hours. The best I search result I got was the following documentation: JIRA Developers Documentation

Please assist, I'm not sure What I'm missing

You can get that information either from the createmeta or editmeta REST resources.

Use editmeta if you want to retrieve the available options when editing a specific issue. E.g.

GET /rest/api/2/issue/TEST-123/editmeta

Use createmeta when you want to retrieve the options for a project in combination with an issue type. E.g.

GET /rest/api/2/issue/createmeta?projectKeys=MYPROJ&issuetypeNames=Bug&expand=projects.issuetypes.fields

The customfields with options will be returned like this:

"customfield_12345": {
  "schema": {
    "type": "string",
    "custom": "com.atlassian.jira.plugin.system.customfieldtypes:select",
    "customId": 12345
  },
  "name": "MySelectList",
  "allowedValues": [
    {
      "self": "http://jira.url/rest/api/2/customFieldOption/14387",
      "value": "Green",
      "id": "14387"
    },
    {
      "self": "http://jira.url/rest/api/2/customFieldOption/14384",
      "value": "Blue",
      "id": "14384"
    }
  ]
}
