MONEI Payment Modal is the simplest way to securely collect payments from your customers without them leaving your website.
Collecting payments on your website consists of creating a payment object, and confirming the payment.
1. Create a Payment
Create a Payment on your server with an amount and currency. Always decide how much to charge on the server side, a trusted environment, as opposed to the client. This prevents malicious customers from being able to choose their own prices.
The following parameters are required:
positive integer- Amount intended to be collected by this payment. A positive integer representing how much to charge in the smallest currency unit (e.g., 100 cents to charge 1.00 USD)
string- Three-letter ISO currency code, in uppercase. Must be a supported currency.
string- An order ID from your system. A unique identifier that can be used to reconcile the payment with your internal system.
string- The URL to which a payment result should be sent asynchronously.
Check all available request parameters.
Included in the returned Payment object is a payment
id, which is used on the client side to securely complete the payment process instead of passing the entire Payment object.
2. Confirm the payment
To complete the payment you need to confirm it using monei.js confirmPayment function
monei.js on your checkout page by adding the script tag to the
head of your HTML file.
After the form is submitted MONEI will automatically show a popup window with a payment page to collect payment details and then a 3d secure confirmation screen (if needed)
As an alternative process you can redirect your customer to
payment.nextAction.redirectUrl on the server-side. Check our prebuilt payment page guide
3. An asynchronous request is sent to your server.
MONEI will notify you about a payment status by sending an HTTP POST request to the
callbackUrl. The request body will contain full payment object in JSON format.
This ensures that you get the payment status even when customer closed the browser window or lost internet connection.
The request also contains a
MONEI-Signature header. Verify this signature to confirm that received request is sent from MONEI.
To acknowledge receipt of the request, your endpoint must return a
200 HTTP status code to MONEI. All other response codes, including
3xx codes, indicate to MONEI that you did not receive the event.
If MONEI does not receive a
200 HTTP status code, the notification attempt is repeated. After multiple failures to send the notification over multiple days, MONEI marks the request as failed and stops trying to send it to your endpoint.
