Accept Crypto Payments

This is a break down on how to accept payments with Coinazer.

Overview

To accept a payment, create a transaction using our API our SDKs. Every transaction includes a link that can be used to complete payment.

Modal

Our Modal offers a straightforward and hassle-free payment process for web transactions. It provides the simplest way to integrate and start accepting payments.

API Requirements

To initiate a transaction, you'll need to provide specific information, including email, amount, and transaction reference. However, the only required parameters are the apiKey, email, amount and currency. The table below provides a comprehensive list of the parameters that can be passed during transaction initialization.

Param	Required	Description
apiKey	Yes	Make sure to utilize the appropriate public key from Coinazer depending on whether you are operating in test mode or live mode. For testing purposes, employ the test key, and for actual transactions, utilize the live key.
email	Yes	Customer's email address
amount	Yes	The amount must be at least equivalent to $10 in any currency, such as Naira, Euro, or Kenyan shillings.
Currency	Yes	This is the currency customer's transaction would be carried out with. Supported currencies are USD, EUR, NGN, KES
callback	No	Upon successful payment, this function executes to verify the transaction status using the verify endpoint on the Coinazer API. It's recommended to utilize a script for this purpose.
closeWidget	No	Function that executes when a customer closes the payment window instead of making a payment

If the customer information has already been stored in your database, it can be retrieved from there. Alternatively, you can obtain it from a form, as shown in the example below:

HTML

 <form id="paymentForm">

  <div class="field-wrap">

    <label for="email">Email Address</label>

    <input type="email" id="email-address" required />

  </div>

  <div class="field-wrap">

    <label for="amount">Amount</label>

    <input type="tel" id="amount" required />

  </div>

  <div class="field-wrap">

    <label for="currency">Currency</label>

    <select id="currency">
      <option value="usd">US Dollar</option>
      <option value="ngn">Naira</option>
      <option value="eur">Euro</option>
      <option value="kes">Kesos</option>
    </select>

  </div>

  <div class="form-submit">

    <button type="submit"> Pay with Coinazer </button>

  </div>

</form>

 <script src="https://www.coinazer.com/public/js/embed.blockchain.js"></script>

        new CoinazerPay({
          apiKey: 'test_key_x9084frljmpy18bougd3jnlb47imfzs60itoyr',
          email:  document.getElementById("email-address").value,
          amount: document.getElementById("amount").value,
          currency:document.getElementById("currency").value,
          callback: {
            onLoadEvent: (txStatus) => {
              console.log('Load', txStatus)
            },
            onCloseEvent: () => {
              console.log('Close : ')
            },
            onTransactionCancel: () => {
              alert('Transaction cancelled')
            },
            onSelectedCrypto: (params) => {
              console.log('Selected', params)
            },
            onTransactionSuccess: (response) => {
              console.log('Success', response)
            },
            OnTransactionRestart: (response) => {
              console.log('You restarted this transaction', response)
            },
          },
        }).openWindow()
      })
