Registering a source:

Remember that for this API to work you need to have a credit subscription activated (see how to subscribe).

To start the process just follow these steps:

  • On the top menu, click on “Real-time API
  • Then, click on “Add a new source
  • Select the option “Standard installation


  • On the next screen, give the source you are creating a name;
  • Register the domain of your form (for example, if your form is at”, you should just enter “”);


  • After that select the option “On a website” from the list of options of where you want to use your API.


  • On the screen that will be displayed, you can configure your API permissions for forms, as follows:
    • Allowed statuses: defines which API response statuses will allow form registration.
    • Block domains from providers: enabling this function will prevent the registration of e-mails from ESP domains, such as,, and others.



  • When you click “Finish“, the API installation script will be created and available for use.
  • The details of the API created will be described on this page.

Where to install

In your form, paste the script into the HTML code, in the footer area. This is the ideal option, as it will ensure that the API is only executed after the page has fully loaded.
