How to connect WordPress Fluent Forms to Square Online Checkout?

Hello,

I have a WordPress website using Fluent Forms Pro.

Previously, payments were connected to Square using a custom PHP form. We removed that old form and replaced it with Fluent Forms.

Now we need:
• When customer clicks "Pay Now", they should be redirected to Square Online Checkout.
• When customer selects "Send me payment link", the payment link should automatically be sent to customer's email and phone.

Square items and API tokens are already configured, and this worked with the old PHP form before.

How can we connect Fluent Forms submission to Square Online Checkout correctly?

Thank you.

Hey there, @Ozkn 👋

Looks like Fluent Forms does have an integration that will allow you to connect your form to our payment processing system and allow you to complete payments then and there.

I recommend reading this guide created by Fluent on how to connect Square to complete payments with your forms.

Will keep an eye out for questions! While I'm unable to support Fluent Forms here, I will do my best to point you in the right direction.
