I am working on an iOS app for the client. For Checkout, we are using webURL from the checkout object and taking the user to the web view. To login the customer, I need to send the custom HTTPS header “X-Shopify-Customer-Access-Token”. In order to send the custom header with the URL I need to use WKWebView. I am facing issues with google pay on the checkout screen. When I click on the GPay button it takes me to the GPay website where it says “unexpected developer error, please try again later”. Can someone please tell me what I might be missing?
