Used in conjunction with data-id to specify a non-default API endpoint for retrieving the form definition and submitting the resulting data. This is used mostly for hitting development servers; if you are using data-form-url you do not need this.
If you are using data-id, and your database instance is accessed by a URL other than www2.myngp.com, you likely need to use this attribute.
- Default:
https://api.myngp.com
Example, to load the definition and submit to https://developerboxname.local/
<div class="ngp-form" data-id="12345" data-endpoint="https://developerboxname.local"></div>
