Power Apps PDF generation architecture leveraging Azure Durable Functions, Power Automate, and API Management to orchestrate secure, scalable document creation workflows. Client requests flow from Power Apps through Power Automate and API Management, authenticated via Microsoft Entra ID, to a Function App running .NET 8 Durable Functions that coordinates PDF generation, storage in Azure Blob Storage, and SharePoint Online integration. Managed Identity and Azure Key Vault enforce least-privilege access, while Application Insights and Log Analytics provide end-to-end observability across the pipeline. Fork this diagram on Diagrams.so to customize authentication policies, add additional data sources, or extend the workflow with Azure Communication Services for email delivery. This pattern demonstrates enterprise-grade security and reliability for document automation at scale.
