To create an instance of the Square client to process the payment, you need to have a valid access token. Once you have the access token, you can use the CreateClient method that is already defined in the Payment class to create the client instance.
Here’s how you can do it:
- Obtain an access token from Square by setting up your application in the Square Developer Dashboard and getting the necessary credentials.
- Call the
CreateClient method with the access token as an argument.
For example:
// Replace "YOUR_ACCESS_TOKEN" with your actual access token
await Payment.CreateClient("YOUR_ACCESS_TOKEN");
- Once the client is created, you can call the
QuickPayment method to process the payment.
await Payment.QuickPayment();
Make sure you replace the placeholder values such as “{LOCATION_ID}” and “{UNIQUE_KEY}” with actual values specific to your Square account and payment.
Also, ensure that the ConstructedClient method is called before making any API requests to check if the client has been successfully constructed.
if (await Payment.ConstructedClient())
{
// Client is constructed, proceed with payment processing
await Payment.QuickPayment();
}
else
{
// Client is not constructed, handle the error
Console.WriteLine("Client is not constructed. Please create the client instance first.");
}
Note that the QuickPayment method is marked as private, so if you need to call it from outside the Payment class, you’ll need to change its access modifier to public or internal depending on your needs. 
Hello @amenarts521,
It looks like you’re on the right track with initializing the Square client in C#. To create an instance of the Square client to process a payment, you need to ensure that you have the correct access token and that you’re setting the environment to production if you’re working with real transactions.
public static async Task CreateClient(string accessToken)
{
// Initialize the Square client with the access token and set the environment to production.
_client = new SquareClient.Builder()
.Environment(Square.Environment.Production) // Set to Sandbox for testing.
.AccessToken(accessToken) // Your access token goes here.
.Build();
}
For the QuickPayment method, make sure that you replace {LOCATION_ID} and {UNIQUE_KEY} with actual values. The LOCATION_ID is specific to your Square account and the UNIQUE_KEY is a unique identifier for each transaction to prevent duplicate charges.
private static async Task QuickPayment()
{
// Define the amount and currency for the transaction.
var priceMoney = new Money.Builder()
.Amount(12500L) // Amount in the smallest unit of the currency (e.g., cents for USD).
.Currency("USD") // Currency code.
.Build();
// Create a QuickPay object with the transaction details.
var quickPay = new QuickPay.Builder(
name: "Auto Detailing", // Description of the service or product.
priceMoney: priceMoney, // The Money object defined above.
locationId: "YOUR_LOCATION_ID") // Replace with your actual location ID.
.Build();
// Create a payment link request with a unique idempotency key.
var body = new CreatePaymentLinkRequest.Builder()
.IdempotencyKey("YOUR_UNIQUE_KEY") // Replace with a unique key for this transaction.
.QuickPay(quickPay) // The QuickPay object defined above.
.Build();
try
{
// Attempt to create the payment link.
var result = await _client.CheckoutApi.CreatePaymentLinkAsync(body: body);
// Handle the result of the payment link creation.
}
catch (ApiException e)
{
// Handle any exceptions that occur during the API call.
Console.WriteLine("Failed to make the request");
Console.WriteLine($"Response Code: {e.ResponseCode}");
Console.WriteLine($"Exception: {e.Message}");
}
}
Remember to handle the result of the CreatePaymentLinkAsync call appropriately, depending on whether the payment link was successfully created or if an error occurred.
For more detailed information and best practices on using the Square .NET SDK, you can refer to the Square Developer Documentation. It provides comprehensive guides on configuring a client, making API calls, handling responses, and more.
also i have modified this to try and send the tokenized data back to my localhost where my client awaits the data, but i cant seem to get it to work.

What errors are you getting when trying to tokenize?
Failed to load resource: there server app.css:1 responded with a 404()
Yes. I have a client made in c# that is using the square api. I guess I have to create tokenized data on an html page. Then have it sent back to my localhost:8080. I have tested my client, and it properly notifies me when posts are made to the local host.
My errors are occurring while trying to use the square payments api. I believe my html is fine and is hosted on github
Right, you’ll use the Web Payments SDK to tokenize the card.
I’ve made changes to the html, and the 404 error is coming from a missing css from a library from the payments api.
Were you able to get the token from the Web Payments SDK? What library is it erroring our on?
I have added window.alert after each step and I’m not sure if I really is tokenizing the data creating the customer, or creating the payment object. Neither is sending the json package back to the local host
below is the form ive created for listening for posts to my local host 8080, as well as the html for dealing with the square payments api. also here are the erros i get…

i guess my documents could not send, but i will send the html and css form my project, and the errors from the page. Hopefully you will be able to understand better than i can and help me understand how to figure the Square Payemnts Api.
What version of the Web Payments SDK are you using? Is it [Preformatted text](http://web.squarecdn.com/v1/square.js)?
