How to start a Zip checkout

Add Zip

Add

mavenCentral()

to your repositories then add

implementation 'com.quadpay:quadpay:0.3.8@aar'

to build.gradle

Consult your account manager about the version you should include!

Initialize the Zip SDK

Your merchant id will be provided by your Zip account manager.

QuadPay.initialize(new QuadPay.Configuration.Builder("<your-merchant_id>")
     .setEnvironment(QuadPay.Environment.SANDBOX)
     .setLocale(QuadPay.Locale.US)
     .build()
);

Begin the Zip checkout flow

Once presented the customer will be shown the Zip checkout flow.

final QuadPayCheckoutDetails details = new QuadPayCheckoutDetails();
details.amount = "100";
details.customerFirstName = "Zip";
details.customerLastName = "Customer";
details.customerEmail = "[email protected]";
details.customerPhoneNumber = "+15555555555";
details.customerAddressLine1 = "123 Main St";
details.customerAddressLine2 = "10th Floor";
details.customerPostalCode = "10003";
details.customerCity = "New York";
details.customerState = "NY";
details.customerCountry = "US";
details.merchantReference = "<your-unique-order-id>";

QuadPay.startCheckout(<your activity instance>, details);

Implement the checkout delegate functions

These functions give your application information regarding the result of the Zip checkout flow.

Register for activity results
@Override
public void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {
   if (QuadPay.handleQuadPayActivityResults(
           this,
           requestCode,
           resultCode,
           data
   )) {
       return;
   }
   super.onActivityResult(requestCode, resultCode, data);
}
Checkout Success

This function returns an order id you may use to confirm an order has been created.

@Override
public void checkoutSuccessful(String orderId) {
    // The user has completed checkout -- the order id must be used to confirm the transaction from the backend
}
Checkout Cancelled

This function is called when the user cancels the Zip process or is declined.

@Override
public void checkoutCancelled(String reason) {
    // A reason describing why checkout was cancelled is returned
}

Confirming your Zip orders

As soon as your customer has completed checkout an order id will be issued. To finalize the transaction this order id must be submitted to Zip's confirmation endpoint. The order id will last for 24 hours under default settings to be confirmed.

The timing of your shipping can be any time after you have confirmed the order. When submitting the order id you will have a chance to finalize the order amount.

Post the order id to the confirmation endpoint

See https://docs.quadpay.com/docs/custom-integration-guide#signing-requests for information regarding signing requests

Post:

curl -X post https://gateway.quadpay.com/orders/{orderId}/confirm
  -H 'content-type: application/json' 
  -H 'X-QP-Signature: [signature]'
  -d '{
    "orderId": [orderId],
    "totalOrderAmount": <number>, (optional)
    "taxAmount": <number>, (optional),
    "shippingAmount": <number>, (optional)
  }'

An order id will be returned:

{
  "orderId": [order id]
}

Service after confirmation

Once the order has been confirmed and an order id has been received the user should be guided to a success page.

This order id can also be used to update the order using our normal orders integration api at https://docs.quadpay.com/docs/custom-integration-guide
