Question 1

What is USSD Playground?

Accepted Answer

USSD Playground is a professional testing platform for developers building USSD applications. It simulates real-world USSD sessions with support for multiple providers (Africa's Talking, Arkesel, Nalo, and custom implementations), allowing you to test your endpoints without needing physical devices or live network connections.

Question 2

How do I get started?

Accepted Answer

Simply sign up for a free account, create a new project with your USSD endpoint URL and code, then use our phone emulator to test your USSD flow. You can view detailed logs of each session to debug and optimize your application.

Question 3

What are the different session modes?

Accepted Answer

USSD Playground supports three session modes:

• Implicit Mode - The server manages session state internally. Each request is independent.

• Explicit Mode - Session ID is passed with each request. The client manages session continuity.

• Hybrid Mode - Combines both approaches for maximum flexibility.

Question 4

Which USSD providers are supported?

Accepted Answer

We support Africa's Talking, Arkesel, Nalo Solutions, and custom/standard USSD implementations. Each provider has its own request/response format, and our platform handles the differences automatically.

Question 5

How do I test my USSD endpoint?

Accepted Answer

1. Create a project and enter your endpoint URL
2. Set your USSD code (e.g., *123#)
3. Choose your session mode
4. Use the phone emulator to dial your code
5. Interact with your USSD flow
6. View detailed logs for debugging

Question 6

Can I test without a live endpoint?

Accepted Answer

Yes! You can use USSD Playground for offline development. Simply point to your local development server (e.g., http://localhost:3000/ussd) or use ngrok/similar tools to expose your local endpoint.

Question 7

What information is logged?

Accepted Answer

Each USSD session logs: request payload, response data, timestamp, session ID, step number, and any errors. This helps you debug issues and understand the flow of your USSD application.

Question 8

Is my data secure?

Accepted Answer

Yes! All data is securely stored using Firebase Authentication and Firestore. Your projects and logs are private and only accessible to you. We use industry-standard encryption and security practices.

Question 9

Are there any usage limits?

Accepted Answer

Free accounts have reasonable limits: 10 steps per session, 30-minute session timeout, and 30 requests per minute rate limiting. These limits ensure fair usage and prevent abuse while being generous for development needs.
