Authentication

Unlike Web applications, RESTful APIs are usually stateless, which means sessions or cookies should not be used. Therefore, each request should come with some sort of authentication credentials. A common practice is to send a secret access token with each request to authenticate the user. Since an access token can be used to uniquely identify and authenticate a user, API requests should always be sent via HTTPS to prevent man-in-the-middle (MitM) attacks.

There are different ways to send an access token:

• HTTP Basic Auth: the access token is sent as the username.
• Query parameter: the access token is sent as a query parameter in the API URL, e.g. https://gorest.co.in/public-api/users?access-token=xxxxxxxx.
• OAuth 2: the access token is obtained by the consumer from an authorization server and sent to the API server via HTTP Bearer Tokens, according to the OAuth2 protocol.
• NOTE: To prevent abuse all API calls requires a access-token, which can be obtained by a free registration.

cUrl Examples

                    
1. Create new user
curl -i -H "Accept:application/json" -H "Content-Type:application/json" -H "Authorization: Bearer YOUR-ACCESS-TOKEN" -XPOST "https://gorest.co.in/public-api/users" -d '{"first_name":"Brian","last_name":"Ratke","gender":"male","email":"lew19@roberts.com","status":"active"}'

2. Update existing user with id 123
curl -i -H "Accept:application/json" -H "Content-Type:application/json" -H "Authorization: Bearer YOUR-ACCESS-TOKEN" -XPATCH "https://gorest.co.in/public-api/users/123" -d '{"first_name":"Brian","last_name":"Ratke","email":"lew19@roberts.com","status":"active"}'

3. Delete user with id 123
curl -i -H "Accept:application/json" -H "Content-Type:application/json" -H "Authorization: Bearer YOUR-ACCESS-TOKEN" -XDELETE "https://gorest.co.in/public-api/users/123"
                

Guzzle Http Examples

                    
1. GET request with query parameter authentication:
new GuzzleHttp\Client()->request('GET', 'https://gorest.co.in/public-api/posts?access-token=YOUR-ACCESS-TOKEN', ['verify' => false]);

2. PATCH request with HTTP Bearer Tokens
new GuzzleHttp\Client()->request('PATCH', 'https://gorest.co.in/public-api/users/1', ['verify' => false, 'headers' => ['Authorization' => 'Bearer YOUR-ACCESS-TOKEN'], 'json' => ['first_name' => 'Reynolds', 'last_name' => 'Lockman', 'gender' => 'female']]);

2. DELETE request with HTTP Bearer Tokens
new GuzzleHttp\Client()->request('DELETE', 'https://gorest.co.in/public-api/users/1', ['verify' => false, 'headers' => ['Authorization' => 'Bearer YOUR-ACCESS-TOKEN']]);


                

Response Codes

The following list summarizes the HTTP status codes that are used.

• 200: OK. Everything worked as expected.
• 201: A resource was successfully created in response to a POST request. The Location header contains the URL pointing to the newly created resource.
• 204: The request was handled successfully and the response contains no body content (like a DELETE request).
• 304: The resource was not modified. You can use the cached version.
• 400: Bad request. This could be caused by various actions by the user, such as providing invalid JSON data in the request body, providing invalid action parameters, etc.
• 401: Authentication failed.

• 403: The authenticated user is not allowed to access the specified API endpoint.
• 404: The requested resource does not exist.
• 405: Method not allowed. Please check the Allow header for the allowed HTTP methods.
• 415: Unsupported media type. The requested content type or version number is invalid.
• 422: Data validation failed (in response to a POST request, for example). Please check the response body for detailed error messages.
• 429: Too many requests. The request was rejected due to rate limiting.
• 500: Internal server error. This could be caused by internal program errors.
