🛠️ Overview
Bearer authentication is a method where the client includes a token in the request headers to authenticate with the server. This token is typically generated through an OAuth 2.0 flow and is valid for a specific scope or duration.
🔐 Key Concepts
- Token Type: Usually a
Bearer
token (e.g.,Authorization: Bearer <token>
). - Security: Tokens are sensitive and must be transmitted over HTTPS.
- Scope: Tokens may have restricted permissions (e.g.,
read
,write
).
📊 Example Request
GET /api/data HTTP/1.1
Host: example.com
Authorization: Bearer <your_token_here>
📋 Example Response
{
"status": "success",
"message": "Authenticated",
"token_info": {
"issued_at": "2023-10-05T12:00:00Z",
"expires_in": 3600
}
}
📚 Security Considerations
- Always validate the token's expiry and signature.
- Avoid exposing tokens in logs or client-side code.
- Rotate tokens periodically for security best practices.

⚠️ Note: Ensure your token is stored securely (e.g., in environment variables) and never shared publicly.
