Title: Square Payment Failed (Status code CUSTOMER_NOT_FOUND: Last modified: August 18, 2024 --- # Square Payment Failed (Status code CUSTOMER_NOT_FOUND: * Resolved [cori80](https://wordpress.org/support/users/cori80/) * (@cori80) * [1 year, 9 months ago](https://wordpress.org/support/topic/square-payment-failed-status-code-customer_not_found/) * Hello everyone. Using Version 4.7.2. We are receiving the error: Square Payment Failed (Status code CUSTOMER_NOT_FOUND: Customer with ID `XYZ` not found.) * I understand the code means that the provided customer id can’t be found in the merchant’s customers list but this explanation doesn’t make sense to me. Meaning, why the Woo-commerce user (customer) need to be in the merchant’s list for the system to process the order? * Thank you for you help in advance. - This topic was modified 1 year, 9 months ago by [cori80](https://wordpress.org/support/users/cori80/).

Only specific ones. Not that the website had been up and running for long (4 months or so) but from what I can tell, two of the very first registered accounts has the problem above among 50+ * Based on your comment, you’re saying square is trying to find that particular customer in square’s database to validate? I have the sync inventory option enabled on the plugin if it helps any. * Plugin Support [Shameem – a11n](https://wordpress.org/support/users/shameemreza/) * (@shameemreza) * [1 year, 9 months ago](https://wordpress.org/support/topic/square-payment-failed-status-code-customer_not_found/#post-17961027) * Hi [@cori80](https://wordpress.org/support/users/cori80/) * Does this occur with a subscription? However, yes, you are correct. The Square Payment Gateway uses the customer ID to identify the customer in Square’s system, not in WooCommerce. When a payment is attempted, the system checks if the customer ID exists in the Square’s database. If the customer ID isn’t found, it returns the `CUSTOMER_NOT_FOUND` error. * Since you mentioned that this issue is only happening with specific customers, it’s possible that there may have been some issue with how these customer profiles were created or synced in Square.

However, to troubleshoot this issue further, I would recommend checking the customer information in both WooCommerce and Square to ensure it matches. If the issue persists, you may want to consider reaching out to Square’s support for further assistance. * Alternatively, you could ask these customers to update their payment details, which would generate a new customer ID in Square’s system. * Please let us know if this helps or if you need further assistance. * Thread Starter [cori80](https://wordpress.org/support/users/cori80/) * (@cori80) * [1 year, 9 months ago](https://wordpress.org/support/topic/square-payment-failed-status-code-customer_not_found/#post-17969843) * Thank you Shameem. It’s not a subscription. We sell wholesale products to brick and mortar retail stores. There is an approval process and we require our customers to create an account so we can have their reseller certificates etc. * I compared the customer IDs like you suggested. One didn’t match and the other wasn’t in Square’s customer directory. I simply copied and updated the ID on WooCommerce. Hopefully that should fix the issue for that particular customer. * For the one that doesn’t exist. Should I create one manually in the square directory? * Plugin Support [omarfpg a11n](https://wordpress.org/support/users/omarfpg/) * (@omarfpg) * [1 year, 9 months ago](https://wordpress.org/support/topic/square-payment-failed-status-code-customer_not_found/#post-17971927) * Hi [@cori80](https://wordpress.org/support/users/cori80/), * Thank you for the additional details. Did you change your Square account in WooCommerce at any time by any chance? That may have caused the mismatch issue, [as per this detailed reply from Square support in a similar case](https://developer.squareup.com/forums/t/payments-failing-retrievecustomer-error-customer-with-id-xxx-not-found/10676/4). * > I compared the customer IDs like you suggested.

And yes you can try creating one manually, here’s the guide from Square: [https://developer.squareup.com/reference/square/customers-api/create-customer](https://developer.squareup.com/reference/square/customers-api/create-customer). * I’d like to learn more about the root issue first, though; that’s why I’m asking if you switched the Square account at any time in your store. * Please keep us posted! * -OP Viewing 5 replies - 1 through 5 (of 5 total) The topic ‘Square Payment Failed (Status code CUSTOMER_NOT_FOUND:’ is closed to new replies. * ![](https://ps.w.org/woocommerce-square/assets/icon-256x256.png?rev=3234354) * [WooCommerce Square](https://wordpress.org/plugins/woocommerce-square/) * [Frequently Asked Questions](https://wordpress.org/plugins/woocommerce-square/#faq) * [Support Threads](https://wordpress.org/support/plugin/woocommerce-square/) * [Active Topics](https://wordpress.org/support/plugin/woocommerce-square/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/woocommerce-square/unresolved/) * [Reviews](https://wordpress.org/support/plugin/woocommerce-square/reviews/) * 5 replies * 4 participants * Last reply from: [omarfpg a11n](https://wordpress.org/support/users/omarfpg/) * Last activity: [1 year, 9 months ago](https://wordpress.org/support/topic/square-payment-failed-status-code-customer_not_found/#post-17971927) * Status: resolved
