Step-by-step tutorials for common async processing patterns.
When to Use Fire-and-Forget vs Wait-for-Signal
Understand the two core task patterns in async orchestration and learn which one fits your workflow based on whether you need to track external completion.
5 steps
Signal-Based vs Polling-Based Task Completion
Compare two approaches to knowing when an async task is done. Learn when to use polling and when signal-based completion is the better fit.
5 steps
Timeout Strategies for Tasks That Depend on External Systems
Learn how to configure timeouts for async tasks that call slow APIs, wait for payments, or depend on third-party services with unpredictable response times.
5 steps
How to Secure Webhook Endpoints with Token-Based Authentication
Protect your webhook endpoints from unauthorized requests using HMAC signatures, signal tokens, and request validation.
5 steps
Designing Idempotent Webhook Handlers for Async Workflows
Learn how to build webhook handlers that produce the same result regardless of how many times they are called. Prevent duplicate processing and data corruption.
5 steps
The Hidden Cost of Polling for Job Completion
Polling seems simple, but it wastes API calls, adds latency, and hits rate limits. Learn the real costs and better alternatives for tracking async task status.
5 steps
How to Avoid Timeout Errors When Waiting for External Services
Learn patterns to prevent timeout failures when your application depends on slow or unpredictable external APIs, payment processors, and third-party services.
5 steps
Why Webhook Reliability Matters for Payment Processing
Missed or duplicate payment webhooks cause revenue loss, double charges, and customer complaints. Learn how to build reliable payment webhook handling.
5 steps
How to Handle Webhook Delivery Failures Without Losing Data
Learn strategies for dealing with failed webhook deliveries, including retry queuing, dead letter storage, and replay mechanisms to ensure no event is lost.
5 steps
Why Long-Running API Calls Fail in Serverless Environments
Understand why serverless functions time out on long-running tasks and learn patterns to work around execution limits on Vercel, Netlify, and AWS Lambda.
5 steps
What Happens When Your Webhook Endpoint Is Down During a Critical Event
Understand the consequences of webhook endpoint downtime and learn strategies to ensure no events are lost during deployments, outages, or server crashes.
5 steps
Race Conditions in Async Workflows and How to Prevent Them
Learn how race conditions occur in background job processing and async task queues, and apply practical patterns to prevent data corruption and duplicate work.
5 steps
How to Chain Multiple API Calls
Build reliable multi-step API workflows with AsyncQueue. Chain dependent API calls so each step retries independently and your endpoint responds instantly.
5 steps
How API Orchestration Works
Learn how API orchestration coordinates multiple services into reliable workflows using task queues, webhooks, and async patterns.
5 steps
Handling Failures in API Chains
Build resilient multi-step API workflows with retry strategies, compensation logic, dead letter queues, and graceful degradation patterns.
5 steps
Managing State in API Workflows
Learn how to track, persist, and recover workflow state across multi-step API workflows using a task queue and simple database patterns.
5 steps
How to Set Up Webhook Retries
Configure automatic webhook retries with exponential backoff in AsyncQueue to ensure reliable delivery even when endpoints are temporarily unavailable.
5 steps
How to Run Background Tasks on Vercel
Bypass Vercel's serverless function timeout limits by offloading long-running tasks to AsyncQueue. Your function returns in milliseconds.
5 steps
How to Schedule Recurring Tasks with Cron
Set up recurring background jobs using cron expressions in AsyncQueue — no cron servers to manage, with built-in retries and monitoring.
5 steps
How to Process File Uploads in the Background
Offload file processing tasks like image resizing, video transcoding, and PDF generation to AsyncQueue so your upload endpoint responds instantly.
5 steps
How to Handle Long-Running API Calls
Offload slow API calls like AI inference, report generation, and third-party integrations to a background queue so your app stays fast.
5 steps
Async Processing Patterns
Learn common async processing patterns like fire-and-forget, request-reply, fan-out/fan-in, and chaining with a task queue.
5 steps
API Timeout Troubleshooting Guide
Diagnose and fix common API timeout issues, from gateway timeouts to slow upstream services, with practical solutions using task queues.
5 steps
How to Wait for API Responses Asynchronously
Learn how to offload long-running API calls to a background task queue so your application responds instantly while AsyncQueue handles the waiting.
