Stripe - single method prebuit UI, STPAPIClient.shared().publishableKey iOS Swift UiKit - ios

Question

I followed this Doc : https://stripe.com/docs/payments/accept-a-payment?platform=ios&ui=payment-sheet
I am getting these from my backend.
"clientSecret" : "pi_3JUrPkLW44AR......7WElFl",
"stripecustomerid" : "cus_K8......pLu4",
"paymentids" : "pi_3JVA.....R9VmA"
"EphemeralKey" : "ephkey_1JV......kEtnlw"
//PaymentSheet Configuration
let clientSecret = response["clientSecret"].stringValue
let ephemeralSecret = response["EphemeralKey"].stringValue
let cusId = response["stripecustomerid"].stringValue
// MARK: Set your Stripe publishable key - this allows the SDK to make requests to Stripe for your account
STPAPIClient.shared.publishableKey = self.publishableKey
// MARK: Create a PaymentSheet instance
var configuration = PaymentSheet.Configuration()
configuration.merchantDisplayName = "Z*****"
configuration.customer = .init( id: cusId, ephemeralKeySecret: ephemeralSecret)
configuration.returnURL = "payments-example://stripe-redirect"
self.paymentSheet = PaymentSheet(
paymentIntentClientSecret: clientSecret,
configuration: configuration)
after this(payment initiation) I am getting log from stripe :
LOG ANALYTICS: ["product_usage": ["PaymentSheet"], "app_name": "Zucraz", "additional_info": [], "bindings_version": "21.8.1", "apple_pay_enabled": 0, "ocr_type": "none", "os_version": "14.4", "analytics_ua": "analytics.stripeios-1.0", "ui_usage_level": "partial", "publishable_key": "pk_test_51J9Te0LW.........tRQbRP2", "device_type": "iPhone12,1", "event": "mc_complete_init_customer", "app_version": "3.4"]
While calling this method - presenting PaymentSheet
func openPaymentSheet(){
// MARK: Start the checkout process
paymentSheet?.present(from: self) { paymentResult in
// MARK: Handle the payment result
switch paymentResult {
case .completed:
self.displayAlert("Your order is confirmed!")
case .canceled:
print("Canceled!")
case .failed(let error):
print(error)
self.displayAlert("Payment failed: \n\(error.localizedDescription)")
}
}
}
Getting this error
Error Domain=com.stripe.lib Code=50 "There was an unexpected error -- try again in a few seconds" UserInfo={NSLocalizedDescription=There was an unexpected error -- try again in a few seconds, com.stripe.lib:ErrorMessageKey=No valid API key provided. Set `STPAPIClient.shared().publishableKey` to your publishable key, which you can find here: https://stripe.com/docs/keys, com.stripe.lib:StripeErrorTypeKey=invalid_request_error, com.stripe.lib:StripeErrorCodeKey=}
There is nowhere defined in documentation to set STPAPIClient.shared().publishableKey.
still, I tried to set STPAPIClient.shared.publishableKey in my viewcontroller, still getting the error.
Thanks in advance

Answer 1

Don't get confused by Error : "Set STPAPIClient.shared().publishableKey to your publishable key".
Nothing to do with this.
Check your keys if got this kind of error.
The EphemeralKey must look like: ek_test_xxx (secret).
