Hi Klaus34,

I hope this can be done using document download API. There are few steps we need to do.

Please create document downlaod API.
The parameters required for calling the integration which will return the document will be added in path segments of API url.
Call the integration which will return the document id using the values we get from path and save it in local variable.
then once you get the document, use it in http response body.
Now in the interface, use the API url as SafeLink with parameters added in path.
In single click, document will be downloaded

Below is the sample code of the Download Document API

a!localVariables(
local!pathArray:/*Add required parameters required to call integration in pathSegments*/
fn!cast('type!{http://www.appian.com/ae/types/2009}Text?list', http!request.pathSegments),
local!document:/*Call the integration using the parameters in path segments */
tointeger(index(local!pathArray, 1, null)),

local!extensionWhitelist: {"pdf", "txt", "png", "jpg", "jpeg"},
if(
/*
* The path must be only 1 value, the document ID, and that ID must be a number.
* Otherwise, we return a 404 Not Found
*/
or(
isnull(local!document),
not(contains(local!extensionWhitelist, document(local!document, "extension")))
),
a!httpResponse(
statusCode: 404,
body: "404 Not Found",
headers: {}
),
a!httpResponse(
/*
* If the query parameter "attachment" is set to true,
* set an HTTP header that tells the client that the body of the response
* should be downloaded. This overrides the default content-disposition
* of "inline; filename=<filename>.<extension>". We will automatically
* set the content-type and length.
*/
headers: if(
http!request.queryParameters.attachment,
a!httpHeader(
name: "Content-Disposition",
value: concat(
"attachment; filename=""",
document(local!document, "name"),
".",
document(local!document, "extension"),
""""
)
),
{}
),
body: todocument(local!document)
)
)
)
