Developer Guides

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.
