To keep the subscription active, the bot must periodically re-subscribe to the PubSubHubbub topic.

Before hub.lease_seconds expires, the bot sends the following POST request:

curl -X POST https://pubsubhubbub.appspot.com/subscribe \
-H "Content-Type: application/x-www-form-urlencoded" \
--data-urlencode "hub.callback=CALLBACK_URL" \
--data-urlencode "hub.topic=TOPIC_URL" \
--data-urlencode "hub.verify=async" \
--data-urlencode "hub.mode=subscribe" \
--data-urlencode "hub.verify_token=" \
--data-urlencode "hub.secret=" \
--data-urlencode "hub.lease_numbers=LEASE_SECONDS"

Don't forget to replace CALLBACK_URL, TOPIC_URL, LEASE_SECONDS with your values.

[!NOTE] Maximum supported value for LEASE_SECONDS is 432000
