Whether you're sharing APIs with internal teams, partners, or public developers, an API Portal ensures they can understand and use your APIs with confidence. And with Syncloop, managing and using an API Portal becomes effortless, even for beginners.

In this step-by-step tutorial, we’ll guide you through how to use Syncloop’s API Portal from setup to testing, so you can maximize productivity and deliver a smooth developer experience.

Step 1: Login to Syncloop and Navigate to Service Builder

Start by logging into your Syncloop dashboard. From the main interface:

  • Go to Service Builder
  • This is your visual workspace where you’ll define the logic and flow of your API services
Why This Matters: Everything you build here is automatically synced to the API Portal, keeping documentation and logic aligned.
Step 2: Create a New API Service
  • Click on Create New Service
  • Enter a service name and description (e.g., getCustomerDetails)
  • Add required input parameters like customer_id

This defines your API’s interface.

Step 3: Design the API Logic Flow

Drag and drop Syncloop’s built-in components to define your API behavior:

  • Transformer: To manipulate or format incoming/outgoing data
  • HTTP Connector: To call external APIs or databases
  • Ifelse: To add conditional logic
  • Log: To record output for debugging
  • Await/Redo: For async behavior and retries

Once your logic is complete, save and deploy the service.

Step 4: Access the API Portal

After deployment:

  • Navigate to API Portal from your Syncloop dashboard
  • You’ll see all your live API services listed

Each service entry includes:

  • Auto-generated documentation
  • Sample request/response formats
  • Parameter descriptions
  • Authorization settings
Step 5: Use the Built-In API Console

Within the API Portal:

  • Click on any API service
  • Scroll down to the Test Console
  • Input test values for parameters
  • Hit Execute

You’ll receive a real-time response from the API, including:

  • Output data
  • Response time
  • Status code

This helps validate service behavior without using third-party tools like Postman.

Step 6: Manage Versions and Visibility

As you update your services:

  • You can create new versions of your API without affecting current consumers
  • Use visibility controls to:
    • Keep APIs private for internal use
    • Share APIs with partners
    • Make APIs public for broader adoption

Syncloop handles version tracking and access management behind the scenes.

Step 7: Configure Authentication and Access Control

In the Portal settings:

  • Define API keys or use OAuth tokens for access
  • Set rate limits and quotas per user or app
  • Restrict access to specific environments (dev/test/prod)
Security First: Syncloop ensures secure and manageable API access at scale.
Step 8: Collaborate and Share

Once your API is published:

  • Share the API Portal link with developers, partners, or stakeholders
  • Let them explore the documentation and try endpoints themselves
  • Collect feedback based on their usage or questions

This streamlines communication and speeds up integration cycles.

Step 9: Monitor Usage and Logs

From your Syncloop dashboard:

  • View service execution logs
  • Track errors and exceptions
  • Analyze usage patterns

These insights help you:

  • Optimize APIs for performance
  • Identify popular endpoints
  • Troubleshoot faster
Step 10: Maintain and Iterate

Keep your API Portal healthy by:

  • Updating documentation when services change
  • Deprecating old versions gracefully
  • Regularly reviewing access and security policies

Syncloop automates many of these tasks, but proactive maintenance ensures a better developer experience.

Conclusion

The API Portal is more than a technical interface—it’s a strategic asset. With Syncloop, you don’t just manage APIs—you elevate them. From visual design to interactive documentation, from testing to monitoring, everything is built to support seamless development and integration.

Whether you're just getting started or scaling a full developer ecosystem, this tutorial gives you the blueprint to create, expose, and evolve APIs using the power of Syncloop’s API Portal.
