Invalid Api key using RestServer

Invalid API Key using RESTServer

If you're encountering an "Invalid API key" error while using RESTServer, here's a comprehensive solution with step-by-step instructions:

1. Step 1: Correct URL Format

Ensure that your URL follows the correct format. Instead of:

http://localhost/projects/myapi/key/index_put.php

Use this:

http://localhost/projects/myapi/key/index.php

2. Step 2: Create a Valid API Key

Create an API key using sha1 (max 40 characters) in the keys table. Follow these steps:

1. Set is_private_key to 1.
2. Set ip_address to ::1.
3. Create the record and check it again.

Alternative Solution: API Key in PUT Header Variables

For the CodeIgniter RESTServer library, when using the PUT method, the API key should be included in the PUT header variables as an x-www-form-urlencoded type. Use Google Chrome Postman and fill in the fields as shown in the image below:

Additional Solution: Override Authentication Method

You can also override the authentication method in the application/config/rest.php file. Locate the auth_override_class_method section and add the following line:

$config['auth_override_class_method']['key']['*'] = 'basic';

Conclusion

By following the steps outlined above, you should be able to resolve the "Invalid API key" error and successfully use RESTServer with a valid API key.
