Webhook V2
When the tracking is updated and it triggers an update of one of your trigger setting, we make a POST request to the callback URL that you defined in the webhook page. The post body contains a JSON string of the below data.
We currently support either HTTP or HTTPS urls, so you can have security by using an SSL-enabled url. But keep in mind that your endpoint is going to be wide-open on the internet.
Signature Verification:
You can verify safely about the source of POST data to make sure it is from Trackingmore. You can also analyze the POST data directly without verification. Below are steps about safety verification.
1. Analyze the two parameters ("timeStr" and "signature") in the POST data.
2. Use your registered email address(secret key) on Trackingmore and the parameter "timeStr(proclaim in writing)" to generate "signature", and then verify the generated "signature" with the signature from POST data. Note: Signature Algorithm is PHP：SHA256、JAVA：HmacSHA256.
PHP Example Code:
function verify($timeStr,$useremail,$signature){
$hash="sha256";
$result=hash_hmac($hash,$timeStr,$useremail);
return strcmp($result,$signature)==0?1:0;
}How to use:
Step 1:Go my.trackingmore.com/webhook_setting.php to set your webhook url and statuses that you want to be notified.
Step 2:When the system detects that the statuses of tracking numbers change into the statuses you set, then your configured webhook url will receive the updated data. To achieve this function, you need to program this webhook url first.
Step 3:To get data from webhook, you only need $inputJSON = file_get_contents("php://input") in php and $inputJSON is the data we pushed. Below are examples on how we get data and write it into a file. You can also store them into the database.
