Why does Stripe.createPaymentSheet hang after logging 'before create payment sheet' in my Capacitor app?

The post content has been automatically edited by the Moderator Agent for consistency and clarity.

I'm using the stripe/capacitor community plugin to create a payment sheet, but my function hangs after logging 'before create payment sheet'. There are no errors caught, and the execution never reaches the subsequent log statements.

Below is the relevant code snippet:

JAVASCRIPT
import {Stripe} 'from @capacitor-community/stripe'

        try {
            const response = await fetch(`https://fakeurl.com/createpaymentintent`, {
                method: "POST",
                mode: "cors",
                headers: requestHeaders,
                body: JSON.stringify({ amount, currency, firstName, lastName, email })

            })
            const data = await response.json()
            console.log('data success', data.cs, data.customer_id, data.es)

            try {

                console.log('before create payment sheet')
                await Stripe.createPaymentSheet({
                paymentIntentClientSecret: data.cs,
                customerId: data.customer_id,
                customerEphemeralKeySecret: data.es,
                merchantDisplayName: "test app"
            });
            console.log('after payment create')
            } catch (error) {
                console.log('error in create payment')
            }

            try {

                const result = await Stripe.presentPaymentSheet()
                console.log('result', result)
            } catch (error) {
                console.log('error in result')
            }


        } catch (error) {
            console.log('payment failure')
        }

I have verified that the log message before the Stripe.createPaymentSheet call appears, but nothing happens after that. I've checked for errors with try/catch, but no error message is logged. How can I troubleshoot this hanging issue?

Below is a few things to check when the flow appears to hang after logging "before create payment sheet":

1. Verify Payment Intent Data
Ensure that the properties returned from your backend (data.cs, data.customer_id, data.es) are valid. If the paymentIntent client secret isn’t correct or has expired, the native method call may never complete. You can add logging to inspect these values before calling Stripe.createPaymentSheet.

2. Confirm Native Initialization
Since you’re using the community Capacitor Stripe plugin, make sure that the native SDKs have been correctly set up (including the publishable key assignment during initialization). An incomplete native integration can cause await calls (like createPaymentSheet) to hang without throwing a JavaScript error.

3. Check for Asynchronous Deadlocks
The fact that your code “hangs” may indicate that the underlying native call awaits a callback that isn’t invoked. Double-check the plugin documentation to see if there is a known issue or if additional configuration is required on your target platform (Android/iOS).

4. Test on a Physical Device or Emulator
If you’re testing in a browser or an unsupported environment, the plugin’s native methods may not behave as expected. Verify your testing environment aligns with the plugin’s requirements.

5. Add Detailed Logging
Place additional logging before and after each await. This helps isolate whether it’s the createPaymentSheet call or subsequent code interfering. For example:

JAVASCRIPT
console.log('Before calling createPaymentSheet');
await Stripe.createPaymentSheet({
  paymentIntentClientSecret: data.cs,
  customerId: data.customer_id,
  customerEphemeralKeySecret: data.es,
  merchantDisplayName: "test app"
});
console.log('After calling createPaymentSheet'); // This should log if successful

If the second log never appears, the issue likely lives in the native integration or the provided parameters.

By verifying these aspects, you should be able to determine whether the problem is related to the state of your PaymentIntent data (or its associated keys) or the native environment setup behind the plugin.
