External data sources
External tags hold information from external data sources, such as weather services, electricity stock markets, or other API interfaces.
Create external data source
In tree, a new external tag can be created in the External data sources node via the icon.

In addition to custom data sources, several data sources predefined by AnyViz are available:
Current weather | By specifying the location and unit system, the current weather at the desired location can be determined. |
Weather forecast | By specifying the location and unit system, the daily and hourly weather forecast is retrieved. |
Air pollution | Current air pollution data for a specified location. |
Electricity spot prices | Wholesale electricity market prices (see details). |
Data from other systems can be retrieved via cyclic GET or POST requests if the data is available in JSON format. When Custom is selected, the following options appear:

Method | In most cases, data is retrieved via GET. If a request body is needed, POST must be selected. |
URL | The request URL to fetch the data |
Request Body | Only for POST: The JSON payload to be transmitted in the request. |
Interval | Query interval in minutes |
Custom headers | If the destination requires additional request headers (e.g. for authentication), these can be specified in the form of a key/value list. |
Caution: The URL of custom data sources must be whitelisted first. Please contact AnyViz support for this.
