This example will fetch NASA daily picture data every hour and after save using Flows. It will then display title and picture.
Steps:
- Create a Widget

- Create a picture for the daily picture
- Go back to the Layer and add a Text global, call it "json"
- Go to Flows, add a new Flow
- Add an "on load trigger" this will trigger the flow once preset is loaded
- Add a "cron" trigger, with standard format 0 0 * * * it will trigger at every hour at the hour
- Add an Action of type WebGet, as an URI here i am using "https://api.nasa.gov/planetary/apod?api_ke..."
- Add an action to store to a Global, Flows will download the JSON file and assign to the global the local JSON file path
- Finally go back to the text and enter $wg(gv(json), json, .title)$ to show the title from the json
- Then go to the image, turn Bitmap parameter to a formul and use $wg(gv(json), json, .url)$ to show the image
