Overview

The HTTP interface can be used to integrate data and information from HTTP servers or other web services. The data exchange is bi-directional.

• Retrieving data: using polling, data can be retrieved via HTTP GET, PUT and POST requests. The HTTP response may contain XML, JSON or normal text which can be parsed using XPath, JPath or Regex.
• Updating data: via HTTP GET, PUT und POST requests, data including the server item value can be published to the foreign HTTP server. Again, XML, JSON or normal text content can be used.

The interface is available for free. Each defined HTTP data point is decreasing the available license data points by one.
