Course Objective & Scope

Template-based Power Automate flows quickly hit performance walls and failure modes when dealing with nested Apply to each loops, large datasets, complex JSON payloads and transient API errors. This course equips analysts and developers with the patterns needed to build fast, resilient cloud flows.

Participants write Workflow Definition Language (WDL) expressions, replace slow loops with Select and Filter array, apply Trigger Conditions and OData queries, implement Try/Catch/Finally error handling with Scope blocks, modularize logic with Child Flows and integrate REST APIs.

Who Should Attend?

  • Business and systems analysts modeling complex approval and data integration rules in Power Automate
  • Software developers integrating Microsoft 365, Dataverse and external REST services
  • Automation specialists optimizing slow, brittle or high-volume cloud flows
  • Prerequisite: basic familiarity with Power Automate or general JSON/programming concepts

Key Takeaways

  • Filter events at the source using Trigger Conditions, OData queries and FetchXML
  • Eliminate nested loop bottlenecks using Select, Filter array, concurrency controls and WDL expressions
  • Consume external REST APIs cleanly with HTTP actions, Parse JSON schemas and authentication headers
  • Build structured Try/Catch/Finally error handling and diagnostics using Scope and Configure run after
  • Architect reusable Child Flows, environment variables and connection references inside Solutions

Curriculum

Trigger Optimization and Query Filtering
  • Writing Trigger Conditions, preventing infinite update loops and column-level filtering
  • Querying SharePoint, SQL and Dataverse efficiently with OData, FetchXML and pagination
WDL Expressions, JSON and Loop-Free Transformations
  • Core string, date, logical and collection WDL functions with null-safe coalesce expressions
  • Reshaping arrays without slow loops using Compose, Parse JSON, Select and Filter array
Concurrency Control and Advanced Approvals
  • Parallel branches, tuning Apply to each concurrency and avoiding variable race conditions
  • Multi-stage approvals with timeout escalations and interactive Teams Adaptive Cards
HTTP/REST Integrations and Hybrid RPA Bridging
  • Calling REST endpoints and Microsoft Graph with HTTP actions, OAuth2 and custom connectors
  • Triggering attended and unattended Power Automate Desktop (PAD) flows from the cloud
Structured Error Handling, Child Flows and ALM
  • Implementing Try/Catch/Finally patterns with Scope, Configure run after and result()
  • Modular Child Flows, Connection References, environment variables and solution deployments
