Learn about how to integrate notification interfaces provided by Antom.

Features

The supported products and description of these notifications are shown in the following table:

Table 1. Capabilities of notifications

Configure receiving address

You can configure the receiving address of each notification via an interface or in Antom Dashboard. If you use both ways to specify the address, the URL configured in the API takes precedence.

Table 2. Receiving address configuration

Process the notification

1. Verify the signature

The result notification from Antom is signed by Antom. It is recommended to verify the signature and check whether the notification is sent by Antom. You can verify the signature by yourself or by using Antom SDK.

To verify the signature by yourself, see Sign a request and validate the signature. To use Antom SDK, specify the values for the corresponding parameters in the SignatureTool.verify method provided in SDKs:

boolean isSuccess = SignatureTool.verify(httpMethod, path, clientId, rspTimeStr, rspBody, signature, alipayPublicKey);

The value of signature is from the notification header. The following example shows a notification header:

"Content-Type": "application/json", "Request-Time": "2019-07-12T12:08:56+05:30", "client-id": "T_111222333", "Signature": "algorithm=RSA256,keyVersion=1,signature=jTOHqknjk%2fnDjEn8lfg%2beNODdoh2eHGJV%2blvrKaDwP782WxJ7ro49giqUu23MUM8sFVVNvhg32qHS3sd4O6uf5kAVLqztqNOPJFZcjw141EVi1vrs%2bIB4vU0%2fK%2f8z2GyWUByh2lHOWFsp%2b5QKCclXp%2bjacYqWYUur5IVbuebR1LoD5IiJ7u7J9qYriFxodkxmIAJYJyJs7mks2FWHh2YePLj3K%2f4B65idy7RBKqY1NN1XcvqnbQmlfCH8CIv75bg%2fr9sGmPE5a%2bYgL8N9Q41buGwMSq1IcNsbceMbyPhw5Z5HnJ7tPz12fvdSi0cEicPikDthQ2EQFmtpntXcAc%2fHA%3d%3d"

2. Return a receipt acknowledgment message

After verifying the signature and confirming that the notification is from Antom, you need to return a receipt acknowledgment message to Antom to inform Antom of a successful receipt of the notification. No digital signature is required for the process of returning a receipt acknowledgment message.

The example below shows the header of the message you send to Antom:

"Content-Type": "application/json", "response-time": "2019-07-12T12:08:56+05:30", "client-id": "T_111222333",

The example below shows the body of the message you send to Antom:

{  "result": {     "resultCode":"SUCCESS",     "resultStatus":"S",     "resultMessage":"success"  } }

If no such message is returned to Antom due to operation or network issues, Antom will automatically resend the asynchronous notification within 24 hours for up to seven times or until the correct response is received. The sending intervals are as follows: 0s, 2 min, 10 min, 10 min, 1 h, 2 h, 6 h, and 15 h.

Note: Record the processed notifications received from Antom for a payment request, and properly handle the idempotency to avoid processing a single request multiple times.
