Hi Shopify Team,
Can you tell us how to resolve using checkoutCompleteWithCreditCardV2 get access denied,
We want to use storefront api and private app in our embed system app.
Hey @deanlin
To use the checkoutCompleteWithCreditCardV2 mutation, your app must be a Sales Channel with the Payment Processing Access granted.
Note also that your app should be a public app - you can check out how to turn the app into a Sales Channel in the documentation here.
Here’s a handy tutorial on creating a checkout with the Storefront API. Hope that helps.
Hi Sir,
Does it require OAuth instead of storefront access token when using public app?
Second, is that possible to use Shopify Storefront API or any possible way to let customer accomplish the payment without via a web browser?
Because we think of implementing an app in our embed system, which let customers can buy our E-Store products.
Hey @deanlin
That’s correct, all publics app must authenticate with OAuth - OAuth is required to obtain the required token to complete checkouts. Here’s an insight into the OAuth process.
The most common approach is to use the web url and use that web url to open a Webview frame inside your app.
In terms of customer’s completing payment without a web browser, it’s possible to use the [Checkout API directly.](http:// Checkout - REST) I’d look into the “Complete a Payment Using Stripe” section here to get an insight into the process, and also note that you’d need to request payment processing permissions.
According to your reply, If we want to checkout without via web browser, the only way is to create a public app and turn into a Sales Channel, right?
In other word, the private app has to rely on a web browser to accomplish the payment, is it correct?
Hey @deanlin
That’s correct on both counts. To create checkouts without a web browser, you’d be able to use the checkoutCompleteWithCreditCardV2 mutation only with a public app that has been converted into a sales channel and has had payment processing access granted by Shopify.
The Private app has to use the Web URL, which would mean you’d have to use a browser.
Hi @Luke_K , is there any documentation on how exactly to use the checkoutCompleteWithCreditCardV2 to complete a checkout without the web url?
Would appreciate any examples too if you have any.
