Opencart square payment bug

Hi there! I'm looking for someone to help with an Opencart bug I'm experiencing. I'm currently using Opencart 3.0.x, and am attempting to process payments through Square. Unfortunately, when I try to make a payment, it shows as in-progress but never actually commits. I require someone who understands Opencart and Square payments to help me troubleshoot and find the cause of this bug. If you think you can help, I'd love to hear from you and discuss the project further. Thanks for your time!
