Hosted Checkout Page Integration Steps

The simplest path to adding more payment methods.

Hosted Checkout Page Integration

Follow these steps and quickly add Rapyd Hosted Checkout to your website.

Step 1: Create Your Checkout Experience

Log into the Rapyd Client Portal and start building your own checkout experience. Add your own colors, logo, and select all the payment methods that you would like to accept.

Customize your Checkout page

Checkout enables you to customize the look and feel to match your brand and website experience.

  1. Once you create a Rapyd account, sign in to the Client Portal as described in Accessing the Client Portal and navigate to My Account > Settings > Branding.

    The Checkout Page appears.

  2. Tap the first icon on the toolbar and upload an image file (png, jpg, jpeg, gif) containing your company logo.

  3. Tap the color icon to select the color of the buttons on the display.

  4. In the Fallback URL field, enter the URL of the page that appears when the checkout process is completed or canceled and no specific URLs are provided for complete_checkout_url or cancel_checkout_url when you generate your Checkout page.

  5. Tap the wallet icon to select only the Payment Methods that you want to appear on your Checkout Page.

Choose your accepted payment methods
  1. Add your customer support details (optional).

    Your customized Checkout Page appears in the Preview panel.

  2. Tap Save

Step 2: Generate your Checkout Page

To generate your Rapyd Checkout page, use the Create Checkout Page method.

  1. Before you send your first API request to the Rapyd platform, you need to set up your Authentication Headers including your Request Signature, and then send a HTTPS POST Request to Rapyd which will generate the Rapyd Checkout page.
  1. Once your Headers and Signature setup is complete, request the Checkout Body. The following three mandatory parameters are required for creating a checkout page:
  • Amount
  • Country
  • Currency

The example below shows a list of mandatory and optional parameters used in the body of a Create Checkout Page request. The request should contain at least the three mandatory parameters mentioned above:



amount (mandatory)

The amount of the payment, in units of the currency defined in currency. Decimal.

country (mandatory)

The two-letter ISO 3166-1 ALPHA-2 code for the country. Uppercase.

currency (mandatory)

Three-letter ISO 4217 code for the currency used in the amount field. Uppercase.

complete_checkout_url (optional)

URL where the customer is redirected when checkout is successful. This page can be set dynamically for each generated checkout page as it overrides the fallback URL that was set in the Client Portal.

payment_method_types_include (optional)

List of payment methods that are displayed on the checkout page.

merchant_reference_id (optional)

Identifier for the transaction. Defined by the merchant. Can be used for reconciliation.

requested_currency (optional)

Determines the currency that the customer will use to pay, when it is different from the currency that the merchant wants to receive. Three-letter ISO 4217 code. When this field is set, the checkout page displays the following information:

  • Original amount and currency.
  • The converted amount in the requested currency.
  • The exchange rate.


When the payment_flow_type of the payment method/s that you provide to your customers is a redirect, make sure to provide URLs in the complete_payment_url and error_payment_url parameters.
The customer will be redirected to these URLs after completing a payment.

To determine the payment_flow_type, see List Payment Methods by Country

Step 3: Redirect your customer

Redirect your customer to the URL you received in the response to Create Checkout Page. The redirect URL appears in the redirect_url field and includes all the parameters for the Checkout session.

  • Note: The checkout page expires 14 days after creation by default.

Alternatively, you may specify a page_expiration parameter in the Create Checkout Page request and choose a different value for the expiration of the Checkout page, in Unix time.
