See more REST Examples

When passing a path to a Chilkat REST function, the path parts and query params should be URL encoded. This example explains..

Add-Type -Path "C:\chilkat\ChilkatDotNet47-9.5.0-x64\ChilkatDotNet47.dll"

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

# This example demonstrates how to URL encode the path passed to a REST function.
# It is demonstrated with an Amazon SP API GET request to get details about a listings item for a selling partner.
# See https://developer-docs.amazon.com/sp-api/docs/listings-items-api-v2021-08-01-reference#getlistingsitem

$rest = New-Object Chilkat.Rest

# Connect to the REST server.
$bTls = $true
$port = 443
$bAutoReconnect = $true
$success = $rest.Connect("sellingpartnerapi-eu.amazon.com",$port,$bTls,$bAutoReconnect)

$rest.ClearAllQueryParams()
$rest.AddQueryParam("marketplaceids","XYZABC123")
$rest.AddQueryParam("includedData","offers")

$rest.AddHeader("x-amz-access-token","YOUR_ACCESS_TOKEN")

$authAws = New-Object Chilkat.AuthAws
$authAws.AccessKey = "YOUR_AWS_APP_ID"
$authAws.SecretKey = "YOUR_AWS_APP_SECRET_KEY"
$authAws.Region = "eu-west-1"
$authAws.ServiceName = "execute-api"
$rest.SetAuthAws($authAws)

# The path that is passed to FullRequestNobBody

# Here's a sample path that is not yet URL encoded.
$path = "/listings/2022-07-01/items/ABCDEFGHIJ/100x100_28g_LANCETS(BOXED)"

# The path passed to FullRequestNoBody needs to have the parts URL-encoded.
# The "/" chars are not URL encoded, but the individual path parts should be URL encoded.
# For example:  /listings/2022-07-01/items/ABCDEFGHIJ/100x100_28g_LANCETS%28BOXED%29

# In this case, we'll prepare the path like this:
$sbPath = New-Object Chilkat.StringBuilder
$sbPath.Append("100x100_28g_LANCETS(BOXED)")
# URL encode the contents of the sbPath.
$sbPath.Encode("url","utf-8")
# Prepend the remaining which does not need to be URL encoded.
$sbPath.Prepend("/listings/2022-07-01/items/ABCDEFGHIJ/")

$("URL encoded path: " + $sbPath.GetAsString())

$responseJson = $rest.FullRequestNoBody("GET",$sbPath.GetAsString())
if ($rest.LastMethodSuccess -ne $true) {
    $($rest.LastErrorText)
    exit
}

$($responseJson)
$("----")
