We need someone to make our current order form work with Constant Contact's API so that the data the user enters into the form is stored within our Constant Account while the user is directed to our checkout page.
Experience with the Constant Contact API is a major plus. We need to have this done within the next 24 hours. More details will be provided when the project is awarded.
It is a REST API which can be invoked by using PHP curl from your web form. So, you will pass the information in XML format to PHP curl, and retrieve the status of response by using SimpleXML object so you will know it success or failed. From this point you can continue the process for redirecting to your check-out or fail page. Could be done in a day only.
