CA Spectrum REST API Next Not Working

[Anon Anon]

I am running a REST request with a throttle size of 1 (for testing purposes).  I am retrieving interfaces using the URL and XML shown below.  My problem - the URL for next changes with each request but the body of the data returned shows the data from the first entry and never changes.  With throttle size 1 I expected to see the first, then the second, the third, etc.

So far so good.  However, if I then take the URL from the "next' link I end up with the exact same results with the only difference being the "next" link is changed.  The attribute values returned are unchanged.  I know about changing the &amp to & but that made no difference.  It feels as if the "start=1" parameter is part of the problem.  But even if I change that, manually, to "start=2" I am still returned the first entry.

Ok - so I have been playing around with this further.  It appears next DOES work if I am doing a GET request.  I was able to run the URL below (which is the link href from an earlier call) and it properly returned me the next entry (in this case start=2).  So my problem appears to be isolated to doing a POST.  With this in mind could someone from SUPPORT confirm the issue on their end and make a recommendation?

Pretty sure this is just working as designed. All my code starts with POST and then GET for all the Next links.

[Anon Anon]

I did not see anywhere an explanation that, after performing the initial POST, I needed to change to using GET.  However, my initial tests show what you say appears to be the case.  I will proceed on this basis and update if I find otherwise.  Thank you for your suggestion.

Hi Anon and everyone

Sorry for picking up an old topic, but I have the exact same issue. Did you managed to resolve it?

I have a code in R which is built as follows:
- make a POST request to collect the attributes I need from the alarms
- make a GET request using the "next" link
- repeat the last step until all the alarms have been collected

It never completes the loop succesfully. It awalys stops at some point with a "NullPointerException". I say "some point" because i can't find a pattern: sometimes it fails at the 7th loop, sometimes at 8th, 11th, 2nd... Is there any adjustment needed to get them all?

I would appreciate any help.
