The client_secret Provided does not match any associated PaymentIntent on this account

[waseemakdev]

I'm trying to use flutter_stripe for a stripe connect account, But I always get the same error: The client_secret provided doesn't match the client_secret associated with the PaymentIntend. I've completed all steps according to flutter_stripe but I still face this error.

Below is my code Please check this and help me.
I am stuck at this point from last week.
Thanks in advance.
index.js

const functions = require("firebase-functions");
const stripe = require("stripe")("secret_key");
exports.stripePaymentIntentRequest = functions.https.onRequest(async (req, res) => {
    try {
        let customerId;

        //Gets the customer who's email id matches the one sent by the client
        const customerList = await stripe.customers.list({
            email: req.body.email,
            limit: 1
        });

        //Checks the if the customer exists, if not creates a new customer
        if (customerList.data.length !== 0) {
            customerId = customerList.data[0].id;
        }
        else {
            const customer = await stripe.customers.create({
                email: req.body.email
            });
            customerId = customer.data.id;
        }

        //Creates a temporary secret key linked with the customer
        const ephemeralKey = await stripe.ephemeralKeys.create(
            { customer: customerId },
            { apiVersion: '2020-08-27' }
        );

        //Creates a new payment intent with amount passed in from the client
        const paymentIntent = await stripe.paymentIntents.create({
            amount: parseInt(req.body.amount),
            currency: 'usd',
            customer: customerId,

        })

        res.status(200).send({
            paymentIntent: paymentIntent.client_secret,
            ephemeralKey: ephemeralKey.secret,
            customer: customerId,
            success: true,
        })

    } catch (error) {
        res.status(404).send({ success: false, error: error.message })
    }
});

and the other
PaymentIntent.dart

Future<void> initPaymentSheet(
    {required BuildContext context, required String email, required int amount}) async {
  try {
    // 1. create payment intent on the server
    final response = await http.post(
        Uri.parse(
            'firebase cloud function API link'),
        headers: {
          HttpHeaders.authorizationHeader:
              'Bearer (secret_key)'
        },
        body: {
          'email': email,
          'amount': amount.toString(),
        });

    final jsonResponse = jsonDecode(response.body);
    log(jsonResponse.toString());
    

    //2. initialize the payment sheet
    await Stripe.instance.initPaymentSheet(
      paymentSheetParameters: SetupPaymentSheetParameters(
        paymentIntentClientSecret: jsonResponse['paymentIntent'],
        merchantDisplayName: 'Flutter Stripe Store Demo',
        customerId: jsonResponse['customer'],
        customerEphemeralKeySecret: jsonResponse['ephemeralKey'],

        style: ThemeMode.light,
        testEnv: true,
        merchantCountryCode: 'US',
      ),
    );

    await Stripe.instance.presentPaymentSheet();

    ScaffoldMessenger.of(context).showSnackBar(
      const SnackBar(content: Text('Payment completed!')),
    );
  } catch (e) {
    if (e is StripeException) {
      ScaffoldMessenger.of(context).showSnackBar(
        SnackBar(
          content: Text('Error from Stripe: ${e.error.localizedMessage}'),
        ),
      );
    } else {
      ScaffoldMessenger.of(context).showSnackBar(
        SnackBar(content: Text('Error the Stripe of : $e')),
      );
    }
  }
}

[remonh87]

did you set the publishable key like:

flutter_stripe/example/lib/main.dart

Line 9 in 6e26f1c

Stripe.publishableKey = stripePublishableKey;

? Make sure that the key is the same as on the server. Also see: https://docs.page/flutter-stripe/flutter_stripe/sheet
