Built a JS-widget with a form that is loaded via JavaScript-API (MVP)

We need: - A simple Javascript API to load a form into third-party websites. - A PHP-script to generate an e-mail based on values passed from the form by AJAX Project is to build a simple widget (form) that can be loaded with "1 row of javascript and 1 row of html (<div id="widget"></div>)" through a simple JavaScript API. The widget will be implemented by partner websites (online shops) for their users to submit a form to another third-party, e.g. an online shop for auto-parts integrates a form for their users to inquire for "car insurance" by submitting the form. The form is loaded based on categories the partner website pass when the widget is loaded. In addition some other parameters can be set, see below. Parameters to load the form will be: - publisher-id (online shop, e.g. a car parts shop) - category Based on these parameters, the JS-API will return a form based on the category-value provided. To each category there is a third-party-partner assigned and also the form fields that need to be loaded (e.g. gender, firstname, lastname, e-mail, phone, address, zip, city, country). The form should have client-side validation. Can be achieved by using an existing library. When the user submits the form, an AJAX-call is made to a PHP-script, that will generate an e-mail to a recipient based on the category. All publisher ids are hard-coded. The relationship between a category and relevant partners (e.g. insurance company) will be hard-coded as well. When the AJAX-call is successful, it return a success message to the widget, if it fails, it returns an error. The script should also do some basic validation We will provide: - an example case - html/css for the form This project is an MVP and should be developed as light as possible. If the MVP is successful, we will build the project to be more sophisticated with administration to assign partners/recipients to categories etc. If you have any questions, please ask.
