What i get in Inbox:

I want to get Annotations for all alerts like:

[xMTinkerer]

I've often wondered about a good way to represent those. Would it ever be the case that array would be like REALLY REALLY REALLY huge? Say more than 30 items?

Anyway, thanks for including the payload. That made things much easier. I think we can do this with a couple fun uses of the javascript array map function. Getting the whitespace exactly like you have is not as fun with HTML, so hopefully this is ok? Otherwise we can look into tweaking the html to better visually break the sections up.

Change this line near the top:

properties.commonAnnotations_markup = buildMarkupFromJSON( data.commonAnnotations, true );

to this:

// Dig out the annotation objects
annotations = data.alerts.map( (alert) => { return alert.annotations } );

// Dig out the individual descriptions and summaries and store them separately
desc = annotations.map( (item) => { return item.description } );
summ = annotations.map( (item) => { return item.summary } );

// Put it all together with a nice label
properties.commonAnnotations_markup = 'Description:<br>' + desc.join( '<br>' ) + '<br>Summary:<br>' + summ.join( '<br>' );

// Ignore or remove this part.
//properties.commonAnnotations_markup = buildMarkupFromJSON( data.commonAnnotations, true );
