Hi!
As the title mentions I have a list of ids of existing org headlines and
want create an agenda view listing all of these headlines.
Is there functionality in org-agenda, that allows me to do this?
Best Regards,

Nobody else has offered help yet, so I'll take a shot. What exactly are
your "ids"? Do you mean you have headlines with assigned CUSTOM_ID
properties, and you have a list of values for which you want to show the
headlines in agenda? If so, I think you could just assemble the list in a
command that sticks new search conditions into one of your custom agenda views.
E.g., if you currently had a custom agenda search mapped to "i" for two
different CUSTOM_IDs, like this:
(setq org-agenda-custom-commands
'(("i" tags "CUSTOM_ID=323|CUSTOM_ID=832")))
you could reissue command to get the search done for different list of
custom ids:
(setq org-agenda-custom-commands
'(("i" tags "CUSTOM_ID=153|CUSTOM_ID=932|CUSTOM_ID=293")))
I haven't tested this, but I expect it or something similar would work.
There are probably tweaks you could make, e.g, list could be combined into a
regular expression so you don't need to repeat multiple 'CUSTOM_ID=' sections.

Thanks you! :)

The ids I am talking about are generated by org-id. A list of these
might look as follows:
#+BEGIN_SRC emacs-lisp
'("55b95977-5e5b-4457-bb76-533499bc34e7"
"249d04f4-7352-488c-bf05-1b00578c414a"
"1833d6fc-46bf-4827-93a8-3f8c22310053"
"4d9c0cb1-fb10-4e28-a15b-63ae03169b39")
#+END_SRC

I want to avoid using custom agendas. I aim to use the agenda view as a
method of presenting a list of tasks, not as a search based view
triggered manually by the user (as it is normally used). The closest
example of what I am trying to achieve is the behaviour achieved by
org-contacts (when searching for a contact), which uses the agenda view,
without "polluting" the custom-agenda-selection.
Although this is not the way I wanted to populate my agenda view, I
settled on the same approach used by org-contacts. I define a skip
function that only keeps headlines whose ID is a member of my list of
ids. Here is the code:
#+BEGIN_SRC emacs-lisp
(let ((org-agenda-skip-function
(lambda ()
(if (member (org-id-get (point)) list-of-ids)
nil
(outline-next-heading)))))
;; (org-todo-list) or similar calls
)
#+END_SRC
IIUC, this approach will scan each headline in all my agenda files only
to find those few (usually < 10) I already know how to retrieve, as I
have the relevant IDs. That is why I wanted to know whether I can just
pass those IDs to an agenda creation command which will then simply
render the corresponding headlines as an agenda view.
Kind regards,
