WooCommerce Error "(Status code CUSTOMER_NOT_FOUND: Customer with ID"

scottbotkins — Sat, 20 Sep 2025 06:56:07 GMT

Website A features 100's of subscribers with the WooCommerce Subscriptions and Membership plugin and uses Square for payment processor.

We have cloned Website A into Website B. Website A is still up to capture all of the current subscription payments. We are slowly moving people over to Website B for a new subscription price. When they try to purchase on Website B they get the following error: Square Payment Failed (Status code CUSTOMER_NOT_FOUND: Customer with ID.

Is this because they are already in the Square database on Website A? If so what do we need to do to ensure they can register on Website B? I found https://developer.squareup.com/forums/t/payments-failing-retrievecustomer-error-customer-with-id-xxx-not-found/10676/3 but can't seem to figure out what to do to solve this.

The Square account was switched on Website B.

Hi @scottbotkins !

Thanks for reaching out to the Square Community. API questions can be super tricky here because most of us (moderators) do not have developer background or knowledge. Have you tried asking this in the developer's forum? I know that thread wasn't helpful, but maybe creating your own will generate some better answers.

I'm sorry I can't help more here.
