Using results of one query to feed and iterative query

I could use some help creating an iterative query using results from a REST API. The API lists the first 100 records but in order to go to the next 100 records it requires the the use of the Query Parameter "After" from the last record. For Example I need the query to look like this:

 

 

 

https://website_api/records?first=100  
https://website_api/records?first=100&after=WyIwN2RmYWI3NC01YzFhLTNkNmMtZWRiZi1lOWEyOWRhZDZkYWIiXQ==
https://website_api/records?first=100&after=WyIxMWJhZjE0NC05ZGNiLWZlMjItYzRhYy1hYTYyOWUyYjU2NTIiXQ== 

 

 

 

 

In this case my API call tells me my total number of records is 3020, so with 100 records each, I'll need it to iterate 30 times. I figured out how to calcuate the correct number of iterations based on the records and list them out in the format above.

 

I am stuck on the part where I run the first query, get the last "end_cursor" value, then dynamically feed that value to the next query and so one. Can anyone point me in the right direction.

I ended up creating a function in order to accomplish this. Example in the link below. Would like to be to run the function as a loop instead of listing each step but it currently works.

You can use List.Generate to get the URLs and then Table.AddColumn to retrieve the data.  That would make each http call twice but this should be covered by your web browser engine cache without much impact. It also avoids all the complexity of List.Accumulate or recursive functions.
