For the multi iframe integration method: You use the expressIFrameUrl value in the steps for the transaction.

For the individual iframe option: You use the buttonIFrameUrls.url of the nihaoPayWechatPay APM for the transaction.

For the custom redirect option: You use the redirectUrls.url of the nihaoPayWechatPay APM for the transaction.

Transaction types and implementation methods

Regardless of the implementation workflow you implement, consumers will be redirected to WechatPay to complete their transactions.

Nexio supports the following transaction types for AliPay:

• Sale
  • In an iframe that displays all payment methods available to the customer (based on the customer’s location and the merchant’s configured payment methods)
  • In an individual iframe
    
• Refund

Testing data

WechatPay cannot be tested from inside the United States of America.

For testing data, see WechatPay Test Info on NihaoPay's website.

Response handling

In the one-time-use token request, WechatPay gets returned in the paymentMethod parameter as nihaoPayWechatPay.

Nexio responds with transaction results in one of the following ways, depending on your integration workflow:

• Event messages: This applies to integrations that do not pass a customerRedirectUrl in the request.
• Response fields in the URL: This applies to integrations that do provide a customerRedirectUrl in the request.

In addition to one of the above, if your merchant account is configured to receive webhooks, Nexio provides responses to the webhook URLs that have been registered. For further explanation of the webhook event types, see the webhook Event types table.

For WechatPay, these are the possible webhook event types:

• TRANSACTION_AUTHORIZED
• TRANSACTION_REFUNDED
• TRANSACTION_SETTLED

For information about how to run each of the integration workflows, see Transaction types and integration methods above.

Status workflows

The status of a successful transaction with WechatPay varies, depending on the options you choose.

*Pending status displays as "authorized" or "AUTHORIZED" in the Nexio Dashboard; it displays as 10, meaning "authorized", in the response when querying transactions (for more information about transactionStatus, see the table).
