Pro Third Party Integration
- Google Apps
- Custom Remote Scripts*
* The HTTP Connector allows you to automatically forward submitted data to any remote script, using the HTTP protocol (the same protocol used when a web form is submitted). This can be used to integrate with many third-party services like HubSpot, MailChimp, Google Analytics for Salesforce, or even Twitter. In fact, with the HTTP Connector, any service that relies on a web form submission can work with FormAssembly! This connector is also particularly useful if you already have a form set up and you need to keep using your server-side script. FormAssembly will act as the "middle man," processing your form and delivering all its advanced features, and then forwarding the data so that your existing business process remains uninterrupted.

Their pricing plan includes an option to set up a form for free, then pay per response. This means you don't pile up front costs into questionnaires that don't return you any valuable information. You also don't need to worry about overspending. The cost per response is not per response made, but per response received; e.g. should 1,000 people respond to your survey, but you only need the first 100, only pay for 100 and that's all that Form Assembly will pass on to you; keeping the others on their servers in case you should later choose to also dig into those responses.
