REST API v2: REST delete collection field
When you send an HTTP DELETE request to the following URL, you’ll delete a field from a collection:
https://api.copernica.com/v2/collection/$id/field/$id?access_token=xxxx
The first $id needs to be replaced by the numerical identifier, the ID, of the collection.
The second $id needs to be replaced by the ID or the name of the field you want to delete.
PHP example
The following example demonstrates how to make a call using this method.
    // dependencies
    require_once('copernica_rest_api.php');
    // change this into your access token
    $api = new CopernicaRestAPI("your-access-token", 2);
    // do the call
    $api->delete("collection/{$collectionID}/field/{$fieldID}");
The example above requires the CopernicaRestAPI class.
