HTTP Request Header "Range"

My API integration only returns 25 records by default.  I'd like to return 1000.  I'm attempting to pass the Range parameter through the HTTP Request and cannot figure out the syntax.  

 

[Headers=[Authorization="Basic MDM0M0Mjhj", Range="items=0-1023"]]

 

I recieve this error: "Expression.Error: The 'Range' header must be modified using the appropriate property or method. Parameter name: name Details: Range:items=0-1023"

 

The API integration is expecting this: 

Range:items=0-1023

 

When I pass this in using the Advanced Editor as follows, I also recieve an "Invailid identifier" error.

 

[Headers=[Authorization="Basic MDM0MjU2ZjM0Mjhj", Range:items=0-1023]]

Because the Range parameter is protected or non-typical within a web.contents request, it's best to build the request in "Logic Apps" first.  From Power Bi's Advanced Editor, use Power Query to point the request to the logic app.  The logic app will define the Range parameter.  

 

Power Query Example:

 

let

url="https://westus2.logic..com:443/work..../.../",
body="{
""authHeader"": ""Basic ABCDEFG12345"",
""rangeHeader"": ""items=0-2000""
}",

Source = Json.Document(Web.Contents(url,[
Headers = [#"Content-Type"="application/json"],
Content = Text.ToBinary(body)
]
)),
in
#"Source"

Hi @jherynk 

Which API do you use?

facebook API? If so, please refer to a similar thread.

 

What does the range in your code mean?

numbers of pages,posts.....?

 

Best Regards

@v-juanli-msft I'm using a software called AlertMedia.  It's used in mass notifications like emergencies.  In their documentation the range means number of results.  If you do not pass in a Range header, the system will return 25 results by default. The server also returns a maximum limit of 2,000 results per request.

 

Using Postman, this header returns 100 results.  Note that I've deleted parts of the Auth for security purposes.

 

GET /api/events HTTP/1.1
Host: washcorp.alertmedia.com
Authorization: Basic DJhZDRjYmE0OjhlM
Range: items=0-100
User-Agent: PostmanRuntime/7.13.0
Accept: */*
Cache-Control: no-cache
Postman-Token: 65972c
Host: washcorp.alertmedia.com

Connection: keep-alive
cache-control: no-cache
