PayPal REST API webhook handling

Anyone here setup the webhooks on the PayPal REST API before?

I think I'm over looking something incredibly simple here.

When I create a new billing agreement through the PayPal PHP SDK I'm returned to my store by the following URL..

/paypal-handler-success-test?success=true&token=EC-3K353628LH3197445

I have created a WebHook for the Subscription Created event that posts JSON as follows

That token generated when the user is redirected back to my store does not appear to be in the WebHooks JSON.

How do you link your PayPal users once they are redirected back to your store to the incoming WebHooks?

When PayPal redirects it passes information back to the landing page. You should be able to use $_get() to pull the information off the return. Then from there use php to minuplate the information as needed
