Workflows / States

Lambda Workflows

Lambda states are where your workflow executes custom business logic, turning orchestration into real computation. This collection of workflows showcases how Lambda integrations power everything from data validation and transformation to API calls, enrichment, and complex decisioning. You will see how inputs are passed into functions, how responses are shaped and merged back into the workflow, and how retries, timeouts, and error handling are applied to keep execution resilient. From simple single-purpose functions to coordinated multi-step pipelines, these examples demonstrate how Lambda states bring flexibility and extensibility to every stage of a state machine.

61 workflows

Tournament Bracket Processing

Live-Ops

This workflow processes a round of tournament match results concurrently using a Map state. Each match result is independently validated and recorded, bracket standings are updated, and the workflow determines whether the tournament round is complete. On round completion, Amazon Bedrock generates a highlight recap, and prizes or advancement tokens are distributed to qualifying players.

Player Onboarding Pipeline

Live-Ops

This workflow handles the complete new player onboarding journey. It validates the incoming account registration, assigns a personalised tutorial track based on platform and experience level, generates a dynamic AI welcome message using Amazon Bedrock, then waits for tutorial completion before awarding the starter item pack and marking the player as fully onboarded.

Item Crafting Pipeline

Live-Ops

This workflow manages the full item crafting lifecycle. It validates the player account, checks that the requested crafting recipe is known to the player and all required materials are present in their inventory, runs the forge step to consume materials and produce the output item, generates unique AI-powered lore text for the crafted item using Amazon Bedrock, and awards the finished item to the player’s inventory.

Guild Raid Coordination

Live-Ops

This workflow orchestrates a multi-phase guild raid. It validates the guild roster for eligibility and minimum size, generates an AI-powered raid strategy briefing via Amazon Bedrock, then runs three concurrent combat phases using a Parallel state — each independently resolved with its own loot table. After all phases complete, a final loot distribution step splits rewards across eligible guild members.

Payment Settlement Pipeline

Payment Settlement

End-to-end payment settlement pipeline covering field validation, fraud detection, payment rail authorization, and ledger settlement. Publishes EventBridge events at each major milestone — fraud detected, payment authorized, and settlement complete.

Express Payment Authorization

Payment Settlement

Rapid authorization-only workflow that validates a payment and runs a fraud check before obtaining a payment rail authorization code. Publishes EventBridge events on fraud detection and successful authorization. Does not perform settlement — suited for pre-authorization and holds.

Batch Payment Settlement

Payment Settlement

Processes an array of payments concurrently using a Map state. Each payment is independently validated, fraud-checked, authorized, and settled in parallel. Results are collected into a single batch summary with per-payment status records.

Freight Booking Pipeline

Freight Booking

This workflow models a complete end-to-end freight booking pipeline using AWS Step Functions. It includes booking validation, carrier capacity checks, hazardous materials screening, rate calculation, booking confirmation, and pickup scheduling.

Express Rate Check

Freight Booking

This workflow provides a low-latency express rate quote before a full freight booking is submitted. It checks carrier capacity, calculates indicative rates, and applies a brief Wait for rate propagation before returning a Succeed or Fail terminal state.
