Iterate through table to make API calls with multiple parameters

[MarlonPereira]

Hello!

I have the following table T, containing pairs of keys/secrets to access an API:

Key	Secret
abcd1	1234a
fgh2	5678b

Next, I have a parametrized function F to call an API method: 

= (page, key, secret) =>
 
   let body = "{
                   ""call"":""ListarClientes"",
                   ""app_key"":"&key&",
                   ""app_secret"":"&secret&",
 ...

Finally, I have a simple function I to iterate through multiple pages:

= List.Generate(()=>
[Result = try F(1, key, secret)otherwise null, Page = 1],
each [Result]<>null,
each [Result = try F([Page]+1, key, secret)otherwise null, Page = [Page]+1],
each [Result])

What I need: for each row of table T, run I, and store all the results into one table R- after this step, I already figured out how to transform the results.

I tried something like this

let
keys = A[key],
Cli = List.Transform(keys, each I)
in Cli

 But since I have more than one parameter (in this case, [key] and [secret]), it didn't work. Any sugestions?

Thanks in advance!

instead of List.Generate use Table.AddColumn - column from function call.

Hello, sorry for the delayed response, sudden shift in projects 😕

Your answer was on the right path. What I needed to do: Table.AddColumn(Source, "I", each I([key], [secret])). This way, I've managed to call multiple times each pair key/secret through loop function I.

Thanks!
