Help needed with setting up a parameter for my API (To loop through multiple APIs)

Hi everyone! Basically, I'm trying to create a parameter for my API, where I could feed various IDs to it. The problem is that I get the following error when I try to feed ID to it:

Error:

 

An error occurred in the ‘’ query. Expression.Error: 3 arguments were passed to a function which expects between 1 and 2.

Details:

Pattern=

Arguments=[List]

 

Code used (I'm pretty sure it requires a slight tweak somewhere but I'm not sure where - it works if I remove the bit where I provide API token, however, without the token I cannot access the data, so I just need to figure out how to correctly specify the API key in my Power Query):

 

(ID as text) as table=>

let

Source = Json.Document(Web.Contents("---MY API ADDRESS---",

[RelativePath ="/api/data/"&(ID)&"/"],

[Headers=[#"X-API-KEY"="9999999999999999"]]

))

#"Converted to Table" = Record.ToTable(Source),

#"Pivoted Column" = Table.Pivot(#"Converted to Table", List.Distinct(#"Converted to Table"[Name]), "Name", "Value")

in

#"Pivoted Column"

Hi @Redraidas10 

1.May you can refet to the following code

e.g 

Source = Json.Document(Web.Contents(PARAM_API_BASE_URL, [RelativePath = "/project/testprj", Headers = [Authorization = "Basic " & Binary.ToText(Text.ToBinary(PARAM_API_USERNAME & ":" & PARAM_API_USER_PASSWORD), BinaryEncoding.Base64), #"APIKey" = PARAM_API_KEY]]))

And you can refer to the following link.

2.You can try to the following solution.

a.select "Web" in get data in Power BI Desktop.

b.input the URL in basic.

3.Select the "Web API" to access and input your key.
