ExtendedAttributes are being ignored in Update Events REST Endpoint

The endpoint is looking for any parameters that match the format: __extendedattribute_{attributename}

If you had an extended attribute with the name: description, you would add a parameter named:

__extendedattribute_description

Thanks but that doesn't seem to work with Telligent 11.

I keep getting "ExtendedAttributes": null, regardless of the variations on the naming.

ExtendedAttributes:EventStatus
__ExtendedAttribute_EventStatus:1
EventStatus:1

Including using __ExtendedAttribute_EventStatus with and without additional parameter.

Looks like I will need to make use of another approach.

You will need to share the full request, immediately I can tell you its  __ExtendedAttribute_EventStatus=1, no colons

The code below will work.  There is an issue in the endpoint when it attempts to read the value of the extended attributes.  You can work around this by including the value twice:

'__extendedattributes_Test' : 'testvalue',

'Test' : 'testvalue'

Due to the bug and how you have to work around it, you will want to avoid using an extended attribute name that is the same as a parameter used by the endpoint.

jQuery.telligent.evolution.put({
	url: jQuery.telligent.evolution.site.getBaseUrl() + 'api.ashx/v2/calendars/events/{id}.json',
	data: { 
		'id': '1',
		'__extendedattribute_Test': 'testvalue',
        'Test': 'testvalue'
	},
	success: function(response) {

	}
});

Many thanks, I ended up going with another approach to store the extra information I needed.
