Integration Inquiry: FileMaker POS with Square Terminal

Subject: Integration of Square Terminal with a FileMaker POS System

Dear Square Support Team,

I hope this message finds you well.

I am in the process of developing a Point of Sale (POS) system using FileMaker and am keenly interested in integrating it with the Square Terminal for payment processing. The objective is to create a seamless experience where transactions made in our FileMaker POS can be processed directly through the Square Terminal.

I would greatly appreciate it if you could provide guidance or point me to any resources that detail how this integration might be accomplished. Are there any existing APIs, SDKs, or documentation specifically tailored for this purpose? Additionally, are there any known constraints or challenges I should be aware of when trying to integrate FileMaker with Square Terminal?

Thank you in advance for your time and assistance. I am looking forward to using Square Terminal in our system and ensuring a smooth payment experience for our customers.

Warm regards,


That’s great that you want to integrate with our Terminal API. All of our resources for integrating with the Terminal are listed on our Documentation site. :slightly_smiling_face:

@Gibbons1 I’m not sure I fully understand the question. When you get a moment could you provide more detail as to what your looking to do with our APIs? :slightly_smiling_face:
