To connect your site to Square, you will need to login to your Square account. You will be brought to the square login page and after signing in, to the permissions screen. Click allow on the permissions screen.

  1. Hi Simon – Great post. I did exactly what you specify above, however, Square is still not accepting payment from Woocommerce. This is the message it gave me in the order status screen. “Square Payment Failed (Status code INVALID_ENUM_VALUE: “ is not a valid enum value for `Country` (line 1, character 527)) Order status changed from Pending payment to Failed.”

    Do you know what went wrong here?

    • Hi Daniel, go to WooCommerce > Settings > General and make sure you added the same country as you added in Square. After doing this can you retry doing a payment and see what you get?
