Setup Postman for local API testing

1. Start Your API Locally

Make sure your API is running. For example:

• ASP.NET Core: https://localhost:5001 or http://localhost:5000
• Docker: Check exposed ports and container IP
/ul>

2. Create a New Postman Collection

• Open Postman
• Click Collections > New Collection
• Name it something like Local API Testing
/ul>

3. Add Environment Variables (Optional but Recommended)

• Go to Environments > Add
• Add variables like:
  • baseUrl = https://localhost:5001
  • authToken = (if needed for authorization)
  /ul> /li>
  • Save and select this environment in the top-right dropdown
  /ul>

  4. Create Requests

  • Click New > Request
  • Set method (GET, POST, etc.)
  • Use {{baseUrl}}/api/your-endpoint in the URL
  • Add headers (e.g., Authorization: Bearer {{authToken}})
  • Add body (for POST/PUT) in JSON format
  /ul>

  5. Handle SSL Issues

  If you're using https://localhost, Postman might warn about self-signed certificates:

  • Go to Settings > General
  • Turn SSL certificate verification to OFF
  /ul>

  6. Test and Debug

  • Send requests and inspect responses
  • Use Postman Console (View > Show Postman Console) for debugging
  /ul>
