CAP

1. Create a playlist for the alert, and add the CAP alert plugin to its slide
2. Design the slide, and choose whether the alert’s headline or description goes into the placeholder
3. Tag the screens that should show the alert. Click edit on the tag to see its Tag ID
4. On the Team page, create an API key and note it
5. Give your alert provider the tag alert API endpoint, the base address for your region (https://eu-api.playsignage.com or https://us-api.playsignage.com), the Tag ID and the API key

This needs some technical know-how: you send the request an alert provider would send. The example uses curl (macOS and Linux; on Windows, use Postman). Replace the address (us-api in the example), <tag_id> and <api_key> with your own, and set the effective, onset and expires dates so the alert is active now.

 curl -X POST "https://us-api.playsignage.com/v1/tags/<tag_id>/alert" \
     -H "Content-Type: application/xml" \
     -H "Authorization: <api_key>" \
