How to clean up the FHIR objects in the Postman received as a bundle?

PowerShell Code

# Load the System.Web assembly
Add-Type -AssemblyName System.Web

# Define the OAuth 2.0 endpoint and client credentials
$clientId = "<YOUR-CLIENT-ID>"
$clientSecret = "<YOUR-CLIENT-SECRET"
$tenantId="<YOUR-TENANT-ID>"
$fhirurl = "https://<YOUR-FHIR-SERVICE>.fhir.azurehealthcareapis.com/"

$tokenUrl = "https://login.microsoftonline.com/$tenantId/oauth2/token"


# Create the body for the token request
$body = @{
    grant_type = "client_credentials"
    client_id = $clientId
    client_secret = $clientSecret
    resource = $fhirurl
}

# Convert the body to a URL-encoded string
$bodyEncoded = [System.Web.HttpUtility]::ParseQueryString([System.String]::Empty)
$body.GetEnumerator() | ForEach-Object { $bodyEncoded.Add($_.Key, $_.Value) }
$bodyString = $bodyEncoded.ToString()

# Make the token request
$response = Invoke-RestMethod -Method Post -Uri $tokenUrl -ContentType "application/x-www-form-urlencoded" -Body $bodyString

# Extract the access token from the response
$accessToken = $response.access_token

# Use the access token to make an API call
$apiUrl = "$fhirurl/Condition?_elements=fullurl&_count=500"
$headers = @{
    Authorization = "Bearer $accessToken"
}

# Make the API request
$apiResponse = Invoke-RestMethod -Method Get -Uri $apiUrl -Headers $headers

# Output the API response
$apiResponse

# Check if the count of entries is greater than zero
if ($apiResponse.entry.Count -gt 0) {
    # Create the entries array dynamically
    $entries = @()
    foreach ($anEntry in $apiResponse.entry) {
        $entry = @{
            request = @{
                method = "DELETE"
                url = $anEntry.fullUrl
            }
        }
        $entries += $entry
    }

    # Define the JSON structure
    $jsonData = @{
        resourceType = "Bundle"
        type = "transaction"
        entry = $entries
    }

    # Convert the PowerShell object to JSON
    $jsonString = $jsonData | ConvertTo-Json -Depth 3

    # Output the JSON string
    #$jsonString


    # Send the POST request with the JSON string as the body
    try {


        $postResponse = Invoke-RestMethod -Method Post -Uri $fhirurl -Headers $headers -Body $jsonString -ContentType "application/json"

        # Output the response from the POST request
        #$postResponse
    } 
    catch 
    {
        Write-Error "Failed to send POST request: $_"
    } 
}
else {
    <# Action when all if and elseif conditions are false #>
    Write-Output "There are no items left."
}

Conclusion

This is other ways you can clean up the FHIR objects.
