Custom APIs in API Maker

Introduction

Custom APIs in API Maker are designed to let you focus only on the logic that matters.
You don’t need to deal with boilerplate code, configs, scaling rules, or deployment pipelines, the platform takes care of all of that for you.

Instead of setting up validation, caching, error handling, or logging from scratch, you just write your function, hit Save, and your API goes live instantly.

Think of Custom APIs as writing a simple Node.js or TypeScript function, while API Maker quietly handles the DevOps side, scaling, performance, and security included.

While API Maker can already auto-generate APIs from your database, Custom APIs go a step further. They let you add complex business logic, connect to external services, or build features that aren’t covered by auto-generated endpoints.

Use case of Custom APIs?

They’re especially useful when:

• Auto-generated APIs don’t provide enough flexibility
• You need to connect with third-party services
• Your business rules require custom logic
• You’re building real-time features like notifications, file uploads, or data processing

With Custom APIs, you get the freedom of custom coding combined with the reliability of a fully managed backend.

Why Choose Custom APIs?

Building APIs the traditional way often means spending more time on setup than on actual logic. With API Maker’s Custom APIs, all that overhead disappears, letting you move from idea to production much faster.

Why developers prefer Custom APIs:

• Zero boilerplate: validation, error formatting, and caching are built in, no extra libraries needed
• Instant deploys: write your function, hit save, and it’s live
• Smarter debugging: structured logs and stack traces show up right in the platform
• Easy versioning: test and roll back API versions with a click
• Built for collaboration: share APIs securely with teammates using access controls

You focus on the logic. API Maker takes care of the plumbing, scaling, and delivery, like having a DevOps team built into the platform.

Custom APIs features for developers

Custom APIs in API Maker aren’t just endpoints, they come with a full toolkit that makes building, testing, and maintaining APIs seamless.

• One-click deployment

• No servers, containers, or pipelines to set up. The moment you save your code, it’s live. API Maker quietly takes care of the DevOps in the background.

• Real-time logs and error tracing Every request comes with structured logs and stack traces, pointing you straight to the line of code causing issues. Debugging feels effortless. See how logging works in API Maker.

• Secure secrets management Safely store API keys, OAuth tokens, and database credentials. Secrets are injected at runtime and never exposed in code or repos. Learn more about secrets management.

• Built-in testing panel Each API has an interactive testing console right inside the dashboard. You can send requests, validate inputs, and check responses instantly, no need for Postman. See the API testing panel.

• Versioning and rollbacks Publish new versions, run tests in isolation, and roll back instantly if something breaks, without affecting production traffic.

• Team collaboration Invite teammates, assign roles, and share APIs securely. Built-in access control keeps collaboration safe. More on access management.

• Code utilities and shortcuts Skip the boilerplate with helpers for file handling, validation, caching, and more. Explore the utility classes.

FAQ's

1. Do I need to set up servers or configs?

No. With API Maker, you don’t touch servers, YAML files, or Docker configs. Deployment, scaling, monitoring, and networking are handled automatically. You just write your function logic and hit save, everything else runs on autopilot.

2. Can I use environment variables or secrets?

Yes. API Maker has a Secrets Manager where you can securely store environment variables, API keys, OAuth tokens, or database credentials. They’re encrypted and injected at runtime, so you never have to hardcode sensitive data.

3. How do I test a Custom API?

Every Custom API comes with a built-in testing panel. You can send requests, add headers, validate inputs, and see structured JSON responses instantly. The panel also understands your API versions, schema validations, and authentication rules, so what you see is exactly what runs in production.

4. Can I roll back changes?

Yes. Version control is built in, so you can roll back instantly. If a new release breaks something, you can restore the previous version with a single click, no downtime, no redeployment headaches.

5. Can Custom APIs replace AWS Lambda or Azure Functions?

Often, yes. Custom APIs can be a simpler and more cost-effective alternative to AWS Lambda, Azure Functions, or Edge Functions. You don’t have to worry about memory quotas, cold starts, YAML configs, or deployment pipelines. Scaling, caching, and logging are all baked in.

6. Can I integrate with external APIs and services?

Absolutely. Custom APIs can call third-party APIs, trigger webhooks, or connect to external services just like any Node.js app. With Secrets Manager, you can safely use API keys and credentials for those calls.
