Checkout Integration (Shopify Storefront Api) with Third party app Shopify

[AmanLajpal]

We are creating a flutter mobile app with the Shopify storefront API, but we are facing issues with the integration of checkout to the third-party payment app (Paytm). We are receiving an inappropriate response from the Shopify side so please if anyone can help then do help.

Hi and hello, switch to the functionality Buy Button by Shopify and integrate there logic in your flutter App. After this you are good to go.
