\nThe example code will demonstrate how to build REST API and handle the user authentication (login and registration) with CodeIgniter.<\/p>\n
The following steps will be implemented to create REST API in CodeIgniter<\/b>.<\/p>\n Before getting started, take a look the files structure of CodeIgniter REST application.<\/p>\n To store user’s account information, a table needs to be created in the database. The following SQL creates a The following SQL creates a Import the API key data in the We will use REST Controller library<\/b> to build RESTful web services in CodeIgniter. Follow the below steps to integrate RESTful server in CodeIgniter using REST Controller library.<\/p>\n Note that:<\/span> All the required files are included in the source code, you don’t need to download these files separately.<\/p>\n The User model handles the database related operations (fetch, insert, update, and delete).<\/p>\n\n
