API returning "Not Found" error when accessing /openapi/v3/ – Red Canary Support

Issue

When attempting to call the Red Canary API, I'm only getting an error page (as HTML) in the response, even though I'm using the correct API key and calling https://go.my.redcanary.co/openapi/v3/.

The response error shows:

<!DOCTYPE html>
<html>
<head>
<title>Not Found</title>

<style type="text/css">

Resolution

The URL being called by the API query needs to specify an operation.

See https://go.my.redcanary.co/openapi/v3/docs/index.html for API documentation, which includes the list of available operations.

As an example, instead of using https://go.my.redcanary.co/openapi/v3/, add an operation to the end of the URL, such as endpoints:
https://go.my.redcanary.co/openapi/v3/endpoints

Sample cURL command:

curl --location --request GET 'https://<subdomain>.my.redcanary.co/openapi/v3/endpoints/' \
--header 'X-Api-Key: api123456789' \
--header 'Authorization: Bearer api123456789'

Sample API from Powershell:

$GPGPublicKey = "Customer GPG Public Key from my profile here"
$RCAPIToken = "Customer API Token from Subdomain here"
$APIEndpoint = "https://<SubDomain>.my.redcanary.co/openapi/v3/endpoints"
$AuthBody = @{
    "type"="apiKey"
    "name"="Customer API Token from Subdomain here"
    "in"="body"
}
$AuthHeader = @{
    "X-Api-Key"="Customer API Token from Subdomain here"
}
Invoke-RestMethod -Uri $APIEndpoint -Headers $AuthHeader -Body $AuthBody -Method "Get"
