Requesting nb_outlinks for a given pageUrl via API

Hello all,

I am trying to query the number of clicked outlinks via API for a given URL. However, the number is always 0, even though the URL has outlink clicks for the queried period.

With the following query I get nb_outlinks and nb_uniq_outlinks for the whole website:

Query (1)

https://analyse.dipf.de/wasystem1?
  module=API&
  method=Actions.get&
  idSite=1&
  period=range&
  date=2021-12-27%2C2022-01-02&
  format=json&
  filter_limit=-1&
  token_auth=XXX

If I use the parameter segment= for a certain URL, I get back page views etc., but no number of clicked outlinks, although I can see via the transition report that the URL has outlink clicks in the defined period:

Query (2)

https://analyse.dipf.de/wasystem1?
  module=API&
  method=Actions.get&
  idSite=1&
  period=range&
  date=2021-12-27%2C2022-01-02&
  segment=pageUrl%3D%3Dhttps%3A%2F%2Fwww.example.de%2Ffoo.html&
  format=json&
  filter_limit=-1&
  token_auth=XXX

The same applies if I want to query the actually clicked outlinks. If I use the following query without a segment, I get data back:

Query (3)

https://analyse.dipf.de/wasystem1?
  module=API&
  method=Actions.getOutlinks&
  idSite=1&
  period=range&
  date=2021-12-27%2C2022-01-02&
  format=json&
  filter_limit=-1&
  token_auth=XXX

If I query the endpoint for a specific URL, I get no data:

Query (4)

https://analyse.dipf.de/wasystem1?
  module=API&
  method=Actions.getOutlinks&
  idSite=1&
  period=range&
  date=2021-12-27%2C2022-01-02&
  segment=pageUrl%3D%3Dhttps%3A%2F%2Fwww.example.de%2Ffoo.html&
  format=json&
  filter_limit=-1&
  token_auth=XXX

There is already a similar question in Requesting "Outlinks" for a specific pageUrl. Unfortunately, it is very old and has not been answered.

Can anyone help me further? Perhaps I am constructing the queries incorrectly or using the wrong endpoint. What irritates me most is that I get the correct nb_pageviews etc. with query (2), but the nb_outlinks and nb_uniq_outlinks are 0.

Best regards and thanks in advance,
Patrick
