Hi @chanderparkash we can help you get the error resolved quickly!
Please note that our best customer support is offered by contacting us via our official support site: https://support.autoship.cloud – where our documentation and support contact form can both be found.
First, it looks like you are reading the documentation for a different plugin. Please find the documentation for Square Payments on the official support site for Autoship Cloud here: https://support.autoship.cloud/article/1026-square-payments
Reviewing your question, it also looks like you may need to enable the setting to enable In WooCommerce > Settings >> Payments >> Manage (Square). When you check the box for “Customers Profiles”, this setting will allow the customer’s payment to be tokenized and saved at Checkout to be used for recurring payments (and also future checkouts).
