Sample integration

As a platform, you can create Airwallex connected accounts for your customers underneath your platform account. You can then transact on behalf of connected accounts such as debiting funds from the connected account’s Wallet to pay out to external customers.

Once a connected account is created, you will need to onboard your customer through a KYC process to finish activating their account. Airwallex provides multiple options to onboard your customer. The simplest option is to redirect your customer to an online onboarding form that is hosted by Airwallex. The customer submits their documentation, and Airwallex will handle the verification process, any requests for additional information, as well as the approval or rejection of the request.

You can start the hosted onboarding process by requesting a hosted flow instance for the connected account. You will need your hosted onboarding template id (template) and the connected account id (account_id). You will also need to specify a return_url to which the customer will be redirected once the onboarding is complete.

A successful request returns an onboarding URL (url) and a hosted flow instance ID (id). The onboarding URL must not be shared with the customer until it’s authorized by you to ensure that it’s only intended for this customer.

Authorize the URL using the hosted flow id returned in the previous request. The authorized URL is short-lived so it’s highly recommended that you redirect the customer as quickly as possible.

Note that KYC requirements differ between countries and other regulations. Here’s a sample onboarding form for illustration purposes.

After your customer finishes onboarding, the status of the connected account will transition to SUBMITTED. Confirm the account status by calling Retrieve a Connected Account API.

As you build your integration, you might want to conduct unit and end-to-end testing of your integration. In the demo environment, you can simulate the KYC process and programmatically transition the account status from SUBMITTED to ACTIVE using the connected account simulation API. Simulation APIs are not available in the production environment.

The sample code below shows how to simulate the status transition for the connected account to ACTIVE.

At this point, your connected account is activated!

In some cases, Airwallex may request additional information from your customers if the information initially provided during KYC is deemed insufficient to approve the application. To handle any requests for information (RFI), we recommend integrating our hosted KYC RFI solution, which has a similar integration setup as hosted onboarding.

To successfully link an external bank account, Airwallex must first verify its ownership. Airwallex offers two options to verify the external bank account: Micro-deposits or Open Banking.

In this sample integration, we'll use Open Banking to verify the Linked Account.

Get an Open Banking authentication token

Call Generate a Linked Account authentication API to retrieve a Link Token required to access the Open Banking modal.

Create a Linked Account

Call Create a Linked Account API specifying the external bank account location under Linked Account type (e.g. US_BANK) and corresponding bank account information, including information obtained from your Open Banking modal.

Before you can add funds via direct debit from a Linked Account, you must obtain authorization from the external bank account owner in the form of a signed mandate (or signed agreement). You may submit mandate information while creating a Linked Account, or later by calling Update a direct debit mandate API.

You can subscribe to Linked Account webhook events to receive any Linked Account status transitions. See Linked Account statuses for more information.

Linked Accounts verified by Open Banking could expire if the external bank account owner changes their login credentials, revokes our access to their account, or naturally after a long period of time (typically above one year). If the status of your Linked account returns as REQUIRES_ACTION, call Refresh a Linked Account authentication API to acquire a new Link Token for your Open Banking modal. Once the Linked Account owner has completed the Open Banking modal, call Complete the Authentication Refresh API to reactivate your Linked Account. You do not need another public token for this request.

A successfully verified Linked Account will return SUCCEEDED in the status field. Review status codes to track status transitions when Linked Accounts are created and verified.

Similar to the account status webhook, you can listen to Linked Account webhook events to notify your system that the Linked Account verification is successful.

You can retrieve details of your Linked Account by calling Retrieve a Linked Account API.

After successfully linking BizCo’s Linked Account to its connected account with Airwallex, you can proceed to pull funds from the Linked Account into BizCo’s connected account Wallet using the steps outlined below.

Before you proceed, check funding limits for your platform using Get funding limits API. Platform funding limits determine the maximum amount of direct debit deposits that may be created, and are shared across all Airwallex accounts under your platform account. For more information, see direct debit flight times and funding limits. Contact your Account Manager to increase either the direct debit limit or the Faster Direct Debit limit, and understand our fee schedule for the Faster Direct Debit product.

Call Create a deposit via Direct Debit API to add funds into BizCo’s Wallet by providing BizCo’s Linked Account ID.

Make sure the amount you deposit does not exceed the funding limit.

You can also listen to the deposit.settled webhook to confirm that the deposit is successfully settled into the connected account’s Wallet.

In this sample integration, we will use the Embedded Beneficiary component, which is a pre-built UI element for you to integrate into your own flow for beneficiary (recipient) information collection. It renders the user interface to help you collect required beneficiary information, such as bank account details, business/personal information.

Please note that the Embedded Beneficiary component uses the same API version that you integrate with. As you upgrade API versions, the information rendered in the component will follow suit. This allows you to benefit from the continuous coverage expansion and product enhancements that Airwallex makes over time.

To view and interact with the Embedded Beneficiary component, go to the Embedded Components demo site .

Similar to the Embedded KYC component, you will need to initialize the beneficiary web SDK and add the beneficiary component to your page. For detailed information, see Embedded Beneficiary Component.

Validate a beneficiary

Once the beneficiary payload is retrieved, you can call Validate a beneficiary API to check for errors before creating a beneficiary:

• If validation errors are found, a list of all errors will be returned as a 400 response.
• If all parameters provided for the payout are valid, the endpoint will return a 200 (OK) response.

Create a beneficiary

Proceed to create a beneficiary using the validated beneficiary payload. You can also use the beneficiary payload to update a beneficiary API that you have already saved with Airwallex.

With the beneficiary created, you can use the Embedded transfer component to render the user interface to collect required payout information, such as country/region, beneficiary (recipient) type, payment method, amount, date etc., while displaying other important information, such as currency conversion rates and fees. To view and interact with the Embedded Transfer component, go to the Embedded Components demo site . Similar to the Embedded Beneficiary component, you will need to initialize the payout web SDK and add the payout component to your page. For detailed information, see Embedded Transfer Component.

Note that the payout component does not support Strong Customer Authentication (SCA). You still need to build SCA on top of the component (e.g. two-factor authentications) to comply with regulations such as the second Payment Services Directive (PSD2), if applicable.

After you retrieve the final transfer payload from the Embedded Transfer component, you can call Create a new transfer API. Please make sure that the required beneficiary payload generated using the Embedded beneficiary component has been aggregated into the transfer payload. If the source currency is different from the payout currency, an underlying currency conversion will be booked. By default, the prevailing market rate at the point of conversion will be applied to the underlying currency conversion.

Call Retrieve a transfer API to get the status of the transfer.

The transfer status should transition from SCHEDULED to PROCESSING. Listen to the payout.transfer.funding.funded webhook to confirm that the transfer has been successfully processed.

For detailed information on creating and validating a transfer, see create a transfer and validate a transfer.
