Help Needed with Recursive Pagination based on the value of a parameter

Hi DLEATE 

I'm not able to provide detailed suggestions as I don't have much experience in this kind of recursive pagination. I found some articles and videos for related topics. Hope they would be helpful.

So a Quick Update: 

I am struggling with pagination recursion in M but I have built a manual loop with manual iterations just to make sure I had the code right... I am finding functional language fairly hard to wrap my head around!

I think i need to create a function and call it whilst the variable hasMoreRecords = true but this is day 4 and my brain is literally melting.. 🙂

Anyway whilst the code is crude and ugly I thought it may help someone that was struggling to create a power Query integration with Qualys.

Any advice on how should be done in M is very welcome 🙂

//#"lastID" = lastId,
//#"lastID1" = lastId1,
//#"hasMoreRecords" = hasMoreRecords
],
//lastId1 = jsonResponse{0}[lastId],
//Recursive Loop Here while hasMoreRecords = true
