Office 365 Email Receiver (Webhook)

Triggered by Microsoft Graph subscription notifications. Iterates the webhookBody.value[] envelope and fetches each email by ID. Use this for any inbound webhook / subscription / Outlook email handler.

Steps

#	Activity	What it does
1	LoadEnvVariables	Load Office 365 app credentials from environment
2	Office365	Authenticate with Microsoft Graph (application permissions)
3	Assign	Extract messageId from the Graph notification envelope
4	GetMessagesById	Fetch the full email message by ID

Workflow

# Microsoft Graph change notifications arrive wrapped in {"value": [ ... ]}.
# webhookBody IS that envelope — always iterate webhookBody['value'].
LoadEnvVariables('{"environmentId": "<env-uuid>", "secrets": ["client_id", "client_secret", "tenant_id"]}')
for notification in webhookBody['value']:
    with Office365(client_id, tenant_id, clientSecret=client_secret,
                   emailAddress="inbox@example.com", permissionsType="application"):
        Assign({'messageId': '{{ notification["resourceData"]["id"] }}'})
        emailData = GetMessagesById(messageId=messageId, includeAttachments=True)
        WriteLine("{{ emailData['Subject'] }}")
