Square WooCommerce Plugin: Customers receiving ‘ Bad_request: intent_mismatch’ Error

Tokncbd — Sat, 20 Sep 2025 13:48:43 GMT

Customers are attempting to purchase and receiving an error code: Bad_request: intent_mismatch.

I haven’t seen this one before. Can anyone explain the cause and provide a solution? Thank you!

Really sorry to hear this @Tokncbd. Must be a super frustrating experience for your customers 😔

Just so I understand better - are you using Square's Online Store or a different eComm platform? If the latter, have you reached out to them directly with your issue?

Let me know!

I just started receiving this exact error a few times from customers in the past two weeks. Odd thing is it doesn't happen every time. I have Square hooked up to my Wordpress site, I do not use Square's store front. I'm using the "Woocommerce Square" plugin for this.

Hey there @Esch! Sounds like it could possibly be a browser issue. I wonder if you could ask them to clear their cache and trying again.

If it continues to happen, you may want to consider reaching out to the WooCommerce Support team since they're the ones who handle the integration.

Hopefully one of the two options will get this resolved for you and your customers!

Did you get any information from woocommerce as to how to fix? I had 2 customers receive this error yesterday, so it sounds like I am starting down a similar path...

The problem isn't cache related, it's the "Woocommerce Square" plugin. I downgraded the plugin to 2.08, which was the previous version to what was released, and I haven't had any issues since.
