Is there a way to test the Square payment form before publishing it?

Once you shared the link of the form or embed it on a published website, then your users will be able to fill-up the form and submit it. So before doing that, you can test the Square payment integration by setting it to "Test Mode" and using a dummy card information. Here's how:

1. In the Form Builder, select the Square payment field and then click the wizard icon. In the wizard, kindly change the "Mode" to "Test Mode". After that, save the changes and preview the form.

2. In the test submission, please use the dummy credit card information from Square support documentation. Here's the link: https://developer.squareup.com/docs/testing/test-values.
