Hi @jongman7711

The 400 Bad Request error typically indicates that the server could not understand the request due to invalid syntax. For better assistance, can you provide screenshots showing the issue on your end?

For screenshots, I recommend https://snipboard.io/ for easily sharing screenshots – please follow the instructions on the page, then paste the URL(s) in your reply.

Meanwhile, can you please disconnect and reconnect your Square account, then head over to WooCommerce → Status → Tools, and do the following:

• WooCommerce transients – Clear
• Expired transients – Clear
• Clear template cache – Clear
• Capabilities – Reset Capabilities
• Clear customer sessions -Clear

Next, please clear your browser cache and then check again.

Make sure you have enable debug mode in the Square settings. https://woocommerce.com/document/woocommerce-square/sync-settings/#section-2

If the issue continues, please share a copy of the following:

• System Status Report: Navigate to WooCommerce → Status. Select Get System Report and then Download for Support.
• Fatal Error log: Share a copy of any fatal error log found under WooCommerce → Status → Square Logs.

You could copy and paste your reply or share it via Mozilla Community Pastebin and share the link here. This will help us investigate further and provide you with a more accurate solution.

Let us know how that goes. Looking forward to helping you.

Hi @jongman7711

So the payment doesn’t complete cause of this error? Or is everything functioning properly, and does the error only appear in the console?

Also, have you enabled the debug mode in the Square setting? If you have, could you please share the error log with us? Also, please share the systems status reports again. Try to set a longer expiration time this time around.

Looking forward to hearing from you soon.
