Hello , I am developing an subscription app where I found a requirement from shopify that I need provide an option to update payment method . I dont understand what I have to actually ? is there any list from shopify they accept ? any guideline ?
If you are making a public app, you need to bill your users via the Shopify billing API itself. I’m not super clear on what you are referring to here but if you aren’t using the Shopify billing API to create your subscriptions, that could be the issue.
which payment method does shopify support ? where I can get the list ?
If you are creating a Public app, you can only bill via the Shopify Billing API as mentioned here:

If you want to use your own payment gateways, you’d either need to get written permission from Shopify (should be pretty impossible unless you are a huge app or platform) or make a private app.
