In order to send data reading information to third party servers, Hubkit provides a set of API endpoints which can be used to register and receive data readings right when they get processed by Hubkit.

API Endpoints

For all POST request, the expected Body content is a JSON string containing the URL HubKit should try and send data to.

For Example, a request to should have a Body similar to "" and a valid Content-type: application/json; charset=utf-8 header

POST https://hubkitAddress:29443/readingSubscriber/subscribeAPI endpoint to add or reactivate a reading Subscriber

POST https://hubkitAddress:29443/readingSubscriber/unsubscribeAPI endpoint to remove a reading Subscriber

POST https://hubkitAddress:29443/readingSubscriber/isRunningAPI endpoint to check if a reading Subscriber is active or not
