Accessing web user checkout using store front checkout API

[anupsai_28988]

Hi,

I have been implementing store front API to customise checkout. In that I have created private app and granted access to modify checkout. When I create checkout using API, then it gives me checkout id as "gid://shopify/Checkout/324ssdasd234asd233wde234ddsdfdsy?key=4d4dftdser4ddasdd23rddwd324sd456"
(Note : Its Base64 decoded)

Now, I have checkout token/id (3ba5a280f8f5599250f42185fba140tt, got this from browser URL) for web user, I want to update this checkout using store front API. Is it possible to do  that ? If Yes! then from where I get KEY for this checkout to form gid URL like  gid://shopify/Checkout/3ba5a280f8f5599250f42185fba140tt?key= <?>

Also is it best practice to update checkout like this ? 

Thanks

I have a related question. I am doing exactly what @anupsai_28988 is doing, using JavaScript like this:

btoa('gid://shopify/Checkout/checkout_token?key=checkout_key')

and then passing to a GraphQL query to get back Checkout object details.

This is fine if I've used "checkoutCreate" to create the Checkout, but if I'm going through as an anonymous user, I don't get this "key" query parameter. Is there a way to get to that value from within the checkout flow, maybe from a cookie or Shopify JS object?

Thanks

@anupsai_28988 @JoshS did you guys figured it out how to achieve that?

@filosganga, no, I think what I was trying to do is not possible. I do not rely on being able to do this.
