WebServices connector paging by setting a request header

I’m attempting to aggregate accounts from a WebService endpoint I need to page through by setting a request header of the next query to the value of a response header that was returned in the previous response. The “Paging Tab Configuration” page ( Paging Tab Configuration (sailpoint.com)) of the WebServices connector doc indicates that the “requestHeaders” and “responseHeaders” are both keywords, and the “Paging Based on Response Header Links” page ( Paging Based on Response Header Links (sailpoint.com)) shows how the “responseHeaders” object is used in paging.

My requirement doesn’t match up perfectly, but I took a swing and came up with this in the “Paging Steps” configuration of my account aggregation call:

TERMINATE_IF ( $responseHeaders.offsetToken$ == NULL ) || ($responseHeaders.offsetToken$ == "" )
$requestHeaders.offsetToken$ = $responseHeaders.offsetToken$

It doesn’t work and seemingly would run forever if I let it. I’m guessing because I can’t set the “requestHeaders” object values at this point it’s just repeatedly fetching the first 200 results. Has anybody run into this type of approach before? I suspect I’m going to have to come up with a rule-based approach for this, but hoping somebody here can help me identify something I’ve missed.

Hi @KevinHarrington,

I have a few concerns:

  • Does the endpoint you’re working with support this type of pagination?
  • Is offsetToken set correctly in the response headers? Some APIs use a different header name or might require setting it in the request URL.

If it does not work, I would suggest looking into the Web Services After Operation Rule to implement your requirements.

Yes - the requirement for pagination came from the endpoint administrator and we have validated that it works outside of IdentityNow using Postman calls. The whole point of this post is to try to avoid writing a rule as it appears this might be possible using the standard pagination capabilities.
