What about integrations that Formstack does not offer?
Is the application you want to integrate with Formstack not showing in the Integration Hub? You may be able to use Zapier to connect your Formstack form to the applications you need. Zapier connects your forms to over 650 popular apps, so you never have to export your form responses again! Just like your forms, connections called “Zaps” are set up in minutes, with no coding needed. From then on, you can say goodbye to copy/pasting and manual entry: Whenever you receive a new form submission, Zapier will automatically send the information to every other app you've connected, whether it's a database, mailing list, or chat app. Capture new subscribers for your newsletter when someone fills out your form, auto-reply with personalized emails, and get text message alerts—all done automatically, every time. Whether you're a marketer trying to grow your audience, an event planner putting together a conference, or a business owner sending out customer surveys, Zapier's automated workflows save you time and effort you can re-apply to your bottom line.
