Examples

Create a Customer (https://www.coinqvest.com/en/api-docs#post-customer)

Creates a customer object, which can be associated with checkouts, payments, and invoices. Checkouts associated with a customer generate more transaction details, help with your accounting, and can automatically create invoices for your customer and yourself.

let response = await client.post('/customer', {
    customer:{
        email: 'john@doe.com',
        firstname: 'John',
        lastname: 'Doe',
        company: 'ACME Inc.',
        adr1: '810 Beach St',
        adr2: 'Finance Department',
        zip: 'CA 94133',
        city: 'San Francisco',
        countrycode: 'US'
    }
});

console.log(response.status);
console.log(response.data);

if (response.status !== 200) {
    // something went wrong, let's abort and debug by looking at our log file
    console.log('Could not create customer. Inspect above log entry.');
    return;
}

let customerId = response.data['customerId']; // store this persistently in your database

Create a Hosted Checkout (https://www.coinqvest.com/en/api-docs#post-checkout-hosted)

Hosted checkouts are the simplest form of getting paid using the COINQVEST platform.

Using this endpoint, your server submits a set of parameters, such as the payment details including optional tax items, customer information, and settlement currency. Your server then receives a checkout URL in return, which is displayed back to your customer.

Upon visiting the URL, your customer is presented with a checkout page hosted on COINQVEST servers. This page displays all the information the customer needs to complete payment.

let response = await client.post('/checkout/hosted', {
    charge:{
        customerId: customerId, // associates this charge with a customer
        billingCurrency: 'USD', // specifies the billing currency
        lineItems: [{ // a list of line items included in this charge
            description: 'T-Shirt',
            netAmount: 10,
            quantity: 1
        }],
        discountItems: [{ // an optional list of discounts
            description: 'Loyalty Discount',
            netAmount: 0.5
        }],
        shippingCostItems: [{ // an optional list of shipping and handling costs
            description: 'Shipping and Handling',
            netAmount: 3.99,
            taxable: false // sometimes shipping costs are taxable
        }],
        taxItems: [{
            name: 'CA Sales Tax',
            percent: 0.0825 // 8.25% CA sales tax
        }]
    },
    settlementAsset: 'USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN' // your settlement asset as given by GET /assets (or ORIGIN to omit conversion)
});

console.log(response.status);
console.log(response.data);

if (response.status !== 200) {
    // something went wrong, let's abort and debug by looking at our log file
    console.log('Could not create checkout.');
    return;
}

// the checkout was created
// response.data now contains an object as specified in the success response here: https://www.coinqvest.com/en/api-docs#post-checkout
let checkoutId = response.data['checkoutId']; // store this persistently in your database
let url = response.data['url']; // redirect your customer to this URL to complete the payment

Monitor Payment State (https://www.coinqvest.com/en/api-docs#get-checkout)

Once the payment is captured we notify you via email, webhook. You can also poll GET /checkout for payment status updates:

let response = await client.get('/checkout',  {id: checkoutId});

console.log(response.status);
console.log(response.data);

if (response.status === 200) {
    let state = response.data['checkout']['state'];
    if (state === 'CHECKOUT_COMPLETED') {
        console.log("The payment has completed and your account was credited. You can now ship the goods.");
    } else {
        // try again in 30 seconds or so...
    }
}

Query your USD Wallet (https://www.coinqvest.com/en/api-docs#get-wallet)

let response = await client.get('/wallet', {assetCode: 'USD'});

console.log(response.status);
console.log(response.data);

Query all Wallets (https://www.coinqvest.com/en/api-docs#get-wallets)

let response = await client.get('/wallets');

console.log(response.status);
console.log(response.data);

let response = await client.post('/withdrawal', {
    sourceAsset: 'USDC:GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN', // withdraw from your USD wallet
    sourceAmount: 100,
    targetNetwork: 'BITCOIN', // a target network as given by GET /networks
    targetAccount: {
        address: 'bc1qj633nx575jm28smgcp3mx6n3gh0zg6ndr0ew23'
    }
});

console.log(response.data);

    sourceAmount: 100,
    targetNetwork: 'STELLAR', // a target network as given by GET /networks
