Registering Strava webhook

[boryn]

Strava has a very peculiar way of registering the webhook url at them (https://developers.strava.com/docs/webhooks/):

• first, we do a POST request for a webhook subscription at them
• in the meantime they reply with GET to our webhook url and expect to receive 200
• finally, if they get 200, they confirm the webhook registration to our POST request

Later they normally send data through POST. Handling of these "normal" POST data can be easiliy implemented using this package.

But how to process it dependent on the GET/POST method? With the first GET we have a different way of validation, as well we need to send different response.

So the question is how to handle GET and POST requests to the same url in different ways?
