Setup webhook

• You need to add a webhook in your repository setting to listen to push event
• Create a new webhook with following settings:
  • Payload URL: YourHostAdd:hook_port
    • eg http://192.23.34.5:5000, if your machine's external ip address is 192.23.34.5 and 5000 is configured as hook_port in watchpush.json
  • Content type: application/json
  • Secret: Token that is configured in watchpush.json
  • Check Just the push event.

For more infromation refer: https://developer.github.com/webhooks/

Note

• hook_port is different from the port your app might be listening.
• Make sure hook_port configured in watchpush.json is publically accessible.
• Get request on YourHostAdd:hook_port should return

  Listening to push events on port 'hook_port'

• Package currently support only application/json, so make sure same is configured on github webhook
• Since it need to automatically pull repository use git config credential.helper store and do a manuall pull/push to let git remember your credentials for future requests
