Hey @bhagya19 ,
- After you have the access token from customerAccessTokenCreate and the checkout ID from checkoutCreate, you can use checkoutCustomerAssociateV2 to associate the customer’s token with the checkout id.
- The simplest way for the customer to complete the checkout is to redirect them to the webUrl returned from checkoutCreate. To use the other checkoutCompleteWith___ mutations, payment processing/sales channel status is required.
