How to get variable for a customer from a webhook in WooCommerce

问题

I am using WooCommerce Subscriptions, and have created a web hook for when a customer cancels their subscription...

I want to update a MySQL database record from 'Publish' to 'Delete' upon this event occurring. I have created a new page for it etc. in a delivery URL.

FORM/POST PARAMETERS

webhook_id: 4099
HEADERS

Cf-Connecting-Ip: 212.227.29.24
Content-Length: 15
Total-Route-Time: 0
Host: requestb.in

RAW BODY

webhook_id=4099

But... how do I get any variables from a web hook payload? Its so confusing (newbie here!). I'd like to get either the username or a variable called 'barcode' which is stored for each user/customer, which I can then identify in the separate database and make the change.

Hope that makes sense..!

Help would be appreciated, Many thanks!!

回答1:

The function you have responding to the webhook should listen for the php input stream.

$input = @file_get_contents("php://input");
var_dump($input); //this will output everything sent to your webhook

From here, you can see which properties you'll want to grab.
