Setting up an integration in PixFort is very easy, to do that:
Go to Project's settings page.
Choose Forms tab.
Now choose which integration you want to use, and scroll down to fill up the required information, then click the save button. That's it!
Note: don't forget to change also the form type inside the builder (to do this click on the envelope icon in the blue bar above the form element, then click on Settings tab from the right sidebar and change the form type).
