unable to change the amount charged from iOS app

I think the amount charged is hardcoded to 10.99 usd. I want to change the amount for the payment intent created I tried the below in my iOS app but it didn't work. any suggestions?

` func createPaymentIntent(completion: @escaping STPJSONResponseCompletionBlock) {
var url = URL(string: backendURL)!
url.appendPathComponent("create_payment_intent")

    AF.request(url, method: .post, parameters: ["amount": 4000 , "currency" : "USD"])
               .validate(statusCode: 200..<300)
               .responseJSON { (response) in
                switch (response.result){
                case .failure(let error):
                    completion(nil, error)
                case .success(let jsonResponse):
                    completion(jsonResponse as? [String : Any], nil)
                }
           }
}

Currency

The currency send to Strip server is hardcoded to "usd", whatever the client send in parameters.
line 53
:currency => "usd",

How to use the EphemeralKey create on laravel?

Code 402

I am having the example backend constantly return error code 402. I have changed the variable from the example application from stripeToken to stripe_token and this passes as 200

There are two sample projects. This one uses Stripe iOS Example (Custom), but I am unable to use the Stripe iOS Example (Simple). Is it intended in that way?

Please only file issues here that you believe represent actual bugs in this demo code.
If you're having general trouble with your Stripe integration, please email [email protected] for a faster response.

Logs not displaying in Heroku

For example, when /capture_payment produces a 402 the puts call in log_info does not produce an entry in the Heroku logs.

I tried to add a config.ru with the following contents (per this SO) but that did not work.

Here was my steps:

heroku git:clone -a ns-stripe-payment-intent
git clone [email protected]:stripe/example-ios-backend.git
cd example-ios-backend/ && cp -r * ../../ns-stripe-payment-intent/
cd ns-stripe-payment-intent
echo '$stdout.sync = true' > config.ru
git add . && git commit -am 'logging' && git push heroku master

Any ideas? I'm getting the following error when calling /capture_payment from physical android device and trying to figure out why (works on android emulator, ios physical, ios emulator).

Error: The Source src_XXX does not belong to the Customer you supplied cus_YYY. Please use this Source with the Customer that it belongs to instead

Why can't I send amount float?

Hi there,

I requested amount float number but It's always 400 bad request.

Please explain for me.

Thank you

create_payment_intent always returns 500

It seems this repo stopped working with the latest Stripe releases. I'm testing it against the latest standard integration example. The heroku server returns 500 all the time for create_payment_intent endpoint. Any ideas?

Here are the logs:

403 FORBIDDEN - Could not parse the ephemeral key response in Basic Integration iOS app

I deployed this example backend to Heroku and running the "Basic Integration" iOS app from here: https://github.com/stripe/stripe-ios/tree/21.3.1

Getting this error:

Basic Integration[76811:9679837] Assertion failed: Could not parse the ephemeral key response following protocol STPCustomerEphemeralKeyProvider. Make sure your backend is sending the unmodified JSON of the ephemeral key to your app. For more info, see https://stripe.com/docs/mobile/ios/standard#prepare-your-api: file Stripe/STPEphemeralKeyManager.swift, line 136

Checking at the response with Charles Proxy, it is a 403 FORBIDDEN attempting to connect to this endpoint:
https://stripe-example-church.herokuapp.com/ephemeral_keys?api_version=2020-08-27

I am able to navigate to the heroku website from my browser and get the message "Great, your backend is set up. Now you can configure the Stripe example apps to point here."

Please let me know how can i test this.
Thanks in advance.

More examples

I'm trying to implement Stripe in my iOS app, but I have a hard time finding any backend examples that are live.

Specifically, I'm looking for an example that will let you:

Save a user
Retrieve a user
Make a payment

Preferably in Rails (but any language at this point would do). Any pointers?

RuntimeError - Can't find price for

he problem: when using this method I simply clicked on the purple icon and proceeded to enter my info and created a backendUrl to be used for my app. All works except when it comes to processing the payment as my inventory items(located in firebase) are not able to be retrieved. Therefore, when placing order I get this in swift: "Failed to create a Payment Intent: unknown"

After getting this error I examined the logs in Heroku and came across this: RuntimeError - Can't find price for Guacamole

so it seems that the payment isn't going through because it can not retrieve the price for this item.

Finally I figure I just add "Guacamole" => 2000 to the list above and run it.

SADLY this did not work. I have no prior experience with ruby but when I applied the above to the list I still got the same error: RuntimeError - Can't find price for Guacamole

I did basically what you commented above but it is unable to retrieve prices for items I add to the EMOJI_StORE

Email receipt and customer description

am New to ruby etc just wonder if it’s possible for the backend to be passed a description for customer such as name and not have it hard coded and if it’s possi to automatically send a email receipt?

402 error on /customer/default_source using Stripe 2.4.0 and Sinatra 1.4.8

I'm using Stripe 2.4.0 and Sinatra 1.4.8 for playing with the iOS example (see https://github.com/stripe/stripe-ios).

When the route /customer/default_source is invoked, I receive back the 402 error.

The sequence of calls is the following (using Charles Proxy):

/customer?
/customer/sources
/customer?
/customer/default_source

While call 2 returns the token tok_1AAKzxHeD6mKz6pSbhD6ZKtQ, call 4 returns card_1AAKzxHeD6mKz6pSrY1VtDHH.

Since they do not match, the error is returned back.

I've also noticed there is a mismatch between the documentation and the code provided. In particular, the documentation has the following code for routing the default_source route:

require "json"

post "/customer/default_source" do
  begin
    customer_id = "..." # Load the Stripe Customer ID for your logged in user
    customer = Stripe::Customer.retrieve(customer_id)
    customer.default_source = params[:default_source]
    customer.save
    status 200
  rescue Stripe::StripeError => e
    status 402
    return "Error retrieving customer: #{e.message}"
  end
end

While the code in the example is:

post '/customer/default_source' do
  authenticate!
  source = params[:source]

  # Sets the customer's default source
  begin
    @customer.default_source = source
    @customer.save
  rescue Stripe::StripeError => e
    status 402
    return "Error selecting default source: #{e.message}"
  end

  status 200
  return "Successfully selected default source."
end

In the former params[:default_source] is used while in the latter params[:source] is adopted.

Any clue? Do I need to update the iOS Stripe lib? Using the code as is (with gem files dependencies in the Gemfile) it works as expected.

Thanks, Lorenzo
