    **Important:** For security reasons, it is recommended to avoid hardcoding your API key directly in your code. Using environment variables is a more secure and flexible approach.

## 4. Create and Add SSH Key to GitLab

For detailed instructions, refer to the [official GitLab SSH documentation](https://docs.gitlab.com/user/ssh/#generate-an-ssh-key-pair).

To contribute code to GitLab repositories, you'll need to set up SSH authentication:

1. **Generate an SSH key pair** if you don't already have one:

   ```bash

   ssh-keygen -t ed25519 -C "your_email@example.com"

   ```

2. **Add your SSH key to the ssh-agent**:

   ```bash

   eval "$(ssh-agent -s)"

   ssh-add ~/.ssh/id_ed25519

   ```

3. **Add your public key to your GitLab account**:

   - Copy your public key to clipboard:

     ```bash

     cat ~/.ssh/id_ed25519.pub

     ```

   - Go to GitLab > Preferences > SSH Keys

   - Paste your key and add a descriptive title
