Re: Rest API _ Json _ several pages _ automatically call the next_page_URL

Hi @ImkeF,

 

There always seems to be a hurdle somewhere. Apparently you can schedule a refresh on a dataset with pagination in the M Language, which is the main part I'm trying to achieve.

 

Do you know any ways around this?

Re: Rest API _ Json _ several pages _ automatically call the next_page_URL

Yes Mark, that's an issue. If you skip to the end of the thread that you've mentioned, you'll find a solution for it 🙂

Or check this article which has a very detailled description/solution: http://blog.datainspirations.com/2018/02/17/dynamic-web-contents-and-power-bi-refresh-errors/

If you liked my solution, please give it a thumbs up. An if I did answer your question, please mark my post as a solution. Thanks!

Re: Rest API _ Json _ several pages _ automatically call the next_page_URL

@Paull@ImkeF

 

I am trying to call APIs from Freshservice. After many weeks, I finally was able to call the site which returned only 30 records. I need to be able to paginate. I have visited every single link mentioned on the blogs but I am not able to follow...can any of you please see what I am doing wrong here

 

Source = Json.Document(Web.Contents("https://swinerton.freshservice.com/helpdesk/tickets/filter/all_tickets/?pages",[Headers=[Authorizati... xxxxxxxxx", #"Content_Type"="application/json"]])),
iterations = Source[total_pages], // get the information within the response
url = "https://swinerton.freshservice.com/helpdesk/tickets/filter/all_tickets/?pages", // here goes your URL

FnGetOnePage =
(url) as record =>
let
Source = Json.Document(Web.Contents("https://swinerton.freshservice.com/helpdesk/tickets/filter/all_tickets/?pages", [Headers=[Authorization="xxxx", #"Content_Type"="application/json"]])),
Page = try Source[connections] otherwise null, //get the data of the first page
next = try Source[next_page_url] otherwise null, // the script ask if there is another page
res = [Page=page, Next=next]
in
res,

GeneratedList =
List.Generate(
()=>[i=0, res = FnGetOnePage(url)],
each [i]<iterations and [res][Page]<>null,
each [i=[i]+1, res = FnGetOnePage([res][Next])],
each [Page][Data]),
#"Converti en table" = Table.FromList(GeneratedList, Splitter.SplitByNothing(), null, null, ExtraValues.Error)
in
#"Converti en table"

At which step does the query break and what error-message do you get?

You're missing the let-keyword at the beginning:

FnGetOnePage =
(url) as record =>
let
Source = Json.Document(Web.Contents("https://swinerton.freshservice.com/helpdesk/tickets/filter/all_tickets/?pages", [Headers=[Authorization="xxxx", #"Content_Type"="application/json"]])),
Page = try Source[connections] otherwise null, //get the data of the first page
next = try Source[next_page_url] otherwise null, // the script ask if there is another page
res = [Page=page, Next=next]
in
res,

GeneratedList =
List.Generate(
()=>[i=0, res = FnGetOnePage(url)],
each [i]<iterations and [res][Page]<>null,
each [i=[i]+1, res = FnGetOnePage([res][Next])],
each [Page][Data]),
#"Converti en table" = Table.FromList(GeneratedList, Splitter.SplitByNothing(), null, null, ExtraValues.Error)

On Freshservice site, it says that to iterate through pages, we need to do this api pagination.jpg

 

 

Thus if you see the new query i have appended page to the end of the url,
