How to configure Really Simple SSL Pro for headless WordPress

1. Install and Activate the Plugin:
- Install the Really Simple SSL Pro plugin from the WordPress repository or manually upload the plugin files to the `wp-content/plugins` directory.
- Activate the plugin from the WordPress dashboard[1][2][4].

2. Configure the Plugin:
- Go to the WordPress dashboard and navigate to the Really Simple SSL Pro settings page.
- Configure the plugin settings as needed, such as enabling the 301 .htaccess redirect and setting the redirect method[1][2][4].

3. Enable SSL Certificate:
- Ensure you have installed a free or paid SSL certificate. You can test this by visiting `https://youdomain.com` in your web browser[4].

4. Activate SSL:
- Log into your WordPress dashboard and navigate to the Really Simple SSL Pro settings page.
- Click on the "Activate SSL" button to enable SSL for your website[1][2][4].

5. Configure Redirects:
- Enable the 301 .htaccess redirect option by selecting "Enable" in the settings tab.
- Save any changes made at the bottom of the page[1][2][4].

6. Test Redirects:
- Test your website's new 301 redirect by opening a private browser session and navigating to your website without HTTPS – e.g., `domain.com`. It should automatically redirect to HTTPS[4].

7. Enable HTTP Strict Transport Security (HSTS):
- Enable HSTS to force the redirect from the browser application. This can be done in the Really Simple SSL Pro settings page[1][2][4].

8. Configure Additional Settings:
- Configure additional settings as needed, such as enabling basic authentication or OAuth2 authentication for the REST API[5].

By following these steps, you can configure Really Simple SSL Pro for headless WordPress and ensure a secure and efficient setup for your website.
