Hello I am currently working on a mobile app where I display my shop and where I can use the full functionality of the shop (buying products etc.)
As of right now I have a private app.
I communicate with the Storefront API via graphql which lets me create a checkout, associate the checkout to a customer and even (as the docs state) complete the checkout.
Whenever I create a checkout, it immediatly gets added to abandoned checkouts( is this normal behavior?)
furthermore when I complete the checkout it says the following in the History tab of the order:
Unable to process a payment for €1,00 EUR on the card ending in ••• via card.
My process looks like this:
What is the response from your last step? Are you receiving access denied, a permissions error, or 200? With that information, I will be able to help you troubleshoot.
