I need an integration with a third-party tool that is not listed, how do i do this?

It is impossible for us to connect directly with all SAAS tools. Check if we have a connection with your tool by going to the editor. Add a form, and then click on the button and then on the wall plug. Here you can find all integrations:

We will keep adding integrations, but it might be possible that yours is not here. Now you have two solutions. the first one is is to integrate with Zapier: How to use the Zapier integration

Another option would be to use our embed element. Most tools offer an embed function in which they give you a code snippet that you can embed on your page, more info can be read here: Use the Embed element
