Constructing the download/stream URLs can be done manually using two different approaches:

HttpHandler
Aspx

Both methods end up running the same code and hence are equally good. There are some theoretical advantages of using the HttpHandler as that one is earlier in the .net pipeline and therefore utilizes the IIS better. The disadvantage to this is that the extension of what is requested needs to be known beforehand and as such, this is not always doable.

Using HttpHandler

As the download and stream are implemented as a HttpHandler, it is a bit different than the other endpoints. The URL can be constructed in the following way

http(s)://damurl.com/dmm3bwsv3/{assetid}_{mediaformatid}_{destinationid}_{assettype}_{outputIdent}_{filmstripId}_{accessKey}_{download boolean}_{extension of mediaformat}

the explanation of the ids are as follows

Name	Description
assetid	This is the id of the asset in Digizuite
mediaformatid	The format in which the asset is transcoded is defined in Digizuite. This id corresponds to such a format
destinationid	This implies where the file should be downloaded from. These IDs are accessible in Digizuite under System tools/Destinations
assetype	Determines the type of the asset. Use GetAssetTypes to get a list of all available asset types
outputident	Enum that determines how the file should be output. 11 is default preview (used for stream) and 44 is download
filmstripid	Is there for backward compatibility - i.e. it's not used anymore. Set this to 0.
accessKey	The accessKey that grants access to the api
Download boolean	True = file downloaded and False = file is returned as a stream
Extension of mediaformat	This should be set to whatever the mediaformat is setup to create (i.e. jpg, if the output of the format is a jpg file)

Using aspx

The apsx URL can be constructed in the following manner:

http(s)://damurl.com/dmm3bwsv3/assetstream.aspx?assetid={assetid}&mediaformatid={mediaformatid}&destinationid={destinationid}&accessKey={accessKey}

the explanation of the ids are as follows

Name	Description
assetid	This is the id of the asset in Digizuite
mediaformatid	The format in which the asset is transcoded is defined in Digizuite. This id corresponds to such a format
destinationid	This implies where the file should be downloaded from. These IDs are accessible in Digizuite under System tools/Destinations
accessKey	The accessKey that grants access to the API
