To install the Postman Proxy certificate on an iOS device, follow these steps:
1. Download the Certificate:
- First, locate the `postman-proxy-ca.crt` certificate on your computer. It can typically be found in:
- macOS: `~/Library/Application Support/Postman/proxy`
- Windows: `C:\Users\
2. Transfer the Certificate to Your iOS Device:
- Use AirDrop, email, or any file-sharing method to send the `postman-proxy-ca.crt` file to your iPhone.
3. Install the Certificate on Your iPhone:
- On your iPhone, go to Settings > Profile Downloaded. If you don't see this option, you may need to go to Settings > General > About and look for the certificate installation prompt.
- Tap Install and follow the prompts. You may need to enter your device passcode.
4. Trust the Certificate:
- After installation, navigate to Settings > General > About > Certificate Trust Settings.
- Enable full trust for the Postman Proxy CA certificate by toggling the switch next to it. Confirm by selecting Continue.
5. Verify Installation:
- To ensure the certificate is correctly installed and trusted, you can revisit the Certificate Trust Settings and check that the Postman certificate is listed and trusted.
Once these steps are completed, your iPhone will be able to capture HTTPS traffic through the Postman proxy, enabling you to inspect API calls effectively[2][3][4].
