# Replace your API key and secret
$apiKey = "YOUR_API_KEY"
$apiSecret = "YOUR_API_SECRET"
$zoomUserId = "YOUR_ZOOM_USER_ID"

$meetingDetails = @{
    topic        = "Test Meeting"
    type         = 2
    start_time   = "2023-10-10T10:00:00Z"
    duration     = 30
    timezone     = "UTC"
    agenda       = "Discussing important topics"
} | ConvertTo-Json

$uri = "https://api.zoom.us/v2/users/$zoomUserId/meetings"
$headers = @{
    "Authorization" = "Bearer $(New-JwtToken -ApiKey $apiKey -ApiSecret $apiSecret)"
    "Content-Type"  = "application/json"
}

$response = Invoke-RestMethod -Uri $uri -Method Post -Headers $headers -Body $meetingDetails

Authenticating with the Zoom API

Understanding OAuth and JWT

Authentication is crucial when connecting to any API. The Zoom API supports two primary authentication methods: OAuth and JWT (JSON Web Token).

OAuth is widely used for applications needing to perform tasks on behalf of users, making it suitable for third-party applications accessing user data. However, managing tokens can be complex.
JWT, on the other hand, is simpler and is ideal for server-to-server communication, where the identity is verified through tokens without user interaction.

Determining the best method for your needs will depend on your application's architecture and user engagement requirements.

Obtaining OAuth Tokens

If you choose to use OAuth, the first step is to obtain an OAuth token. Here’s how to do it:

Navigate to your Zoom App Marketplace and create a new app.
Select OAuth as the app type and fill in the required details.
After creating the app, you'll receive a Client ID and Client Secret.

To request an OAuth token via PowerShell, you can use the following example code snippet (substituting your credentials):

$clientId = "your_client_id"
$clientSecret = "your_client_secret"
$tokenUrl = "https://zoom.us/oauth/token"
$authHeader = [Convert]::ToBase64String([Text.Encoding]::ASCII.GetBytes(“$clientId:$clientSecret”))

$response = Invoke-RestMethod -Uri $tokenUrl -Method Post -Headers @{Authorization=("Basic $authHeader")} -Body @{grant_type="account_credentials"}

$token = $response.access_token

Using JWT for Authentication

To authenticate using JWT, you will need to generate a JWT token that includes the necessary claims. Here's how to do that:

$jwtHeader = @{ alg = "HS256"; typ = "JWT" }
$jwtPayload = @{ iss = $clientId; exp = (Get-Date -UFormat %s) + 3600 }

// Example function to generate the JWT
$header = [Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes(($jwtHeader | ConvertTo-Json)))
$payload = [Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes(($jwtPayload | ConvertTo-Json)))
$signature = [Convert]::ToBase64String([Text.Encoding]::UTF8.GetBytes("your_signature")) // Use your own algorithm for signing

$jwt = "$header.$payload.$signature"

With your JWT token in hand, you can proceed to make API calls.

When making API calls, errors may occur. It’s essential to implement robust error handling. Use `Try-Catch` blocks to capture exceptions and ensure your script remains resilient, providing appropriate output in case of error.

try {
    # Your API Call
} catch {
    Write-Host "An error occurred:" $_.Exception.Message
}

Additionally, inspect response statuses to respond accordingly, ensuring your scripts are both informative and user-friendly.

Automating Common Tasks

PowerShell can be used to automate repetitive tasks easily. For example, you might want to schedule daily recurring meetings or automate user reports.
