Hello Casin, Arturo from Mexico writes to you. I am writing to you because at this moment we are in my team developing, or trying to develop an app in react native using Storefront, and we just have the same problem as you. When trying to process payments and complete the checkout we are having the problem of knowing how to generate this token. We do not want to process the payment directly through shopify, but instead process it in our own Spreedly payment processor, and be able to complete this checkout if the payment is successful.
Do you think you can help us if you managed to solve this.
thanks in advance
