Sample Inline Redirect Implementation

You can embed Transflo on your page using our Checkout() JavaScript function. The function responds to your request in accordance with your request configurations. If you specify a callback_url in your request, the function will redirect your users to the provided callback URL when they complete the payment.


<form>
    <script src="https://transflo.io/v1/payment.js"></script>
    <button type="button" onClick="makePayment()">Pay Now</button>
</form>
<script>
    function makePayment(){
        Checkout({
            "public_key": "{public_key}",
            "tx_ref": '' + Math.floor((Math.random() * 1000000000) + 1),
            "amount": 100,
            "currency": "USD",
            "return_url": "https://webhook.site",
            "customer":{
            "email": "[email protected]",
            "first_name":"John",
            "last_name":"Doe",
            },
            "customization": {
                "title": "Test Payment",
                "description": "Payment Description",
                "logo": "https://assets.piedpiper.com/logo.png"
            },
            "meta": {
                "uuid": "uuid",
                "response": "Response"
            }
        });
    }
