Your existing CodeIgniter REST API needs a focused setup, testing, and troubleshooting pass, and I can handle this end to end. I have 10+ years of PHP experience and have delivered 249+ projects involving CodeIgniter, MySQL, REST APIs, integrations, and automated testing. I’ll first review the current CodeIgniter structure, environment configuration, routes, controllers, models, database connection, authentication, and existing API responses. I’ll then test each available endpoint using realistic requests, checking HTTP status codes, validation, error handling, authentication, SQL queries, and response consistency. Any configuration or code issues will be corrected, followed by regression testing to ensure existing functionality remains stable. I’ll also document the tested endpoints and clearly summarize any remaining concerns so the API is easier to maintain and extend. I can start immediately and provide a concise troubleshooting report along with the fixes. If the initial work goes well, I’m also available for the longer-term API maintenance and integration support you mentioned. Is the existing API built with CodeIgniter 3 or CodeIgniter 4?

❤️❤️❤️ Greetings ❤️❤️❤️ I have carefully reviewed your CodeIgniter REST API setup project and understand that you already have an existing API that needs proper setup, endpoint testing, troubleshooting, and stabilization. I am Ozgur Ozbas, a Full-Stack Developer with 10+ years of experience in PHP, Laravel, CodeIgniter, Node.js, MySQL, REST APIs, API integrations, authentication, and backend troubleshooting. I can review the existing CodeIgniter application, configure the environment, verify database connectivity, inspect routes/controllers/models, and test the available REST endpoints using realistic requests. I will specifically check authentication, request validation, HTTP status codes, response structures, MySQL queries, error handling, headers, and endpoint-to-database communication. If there are configuration, routing, framework, or code-level problems, I will identify the root cause and fix them rather than applying temporary workarounds. I can also use Postman or an equivalent API testing workflow to reproduce the existing issues and perform regression testing after the fixes. If the initial task goes well, I am also interested in providing ongoing API maintenance, integrations, debugging, and feature development. Q1. Is the existing project running on CodeIgniter 3 or CodeIgniter 4? Q2. What is the main API issue currently—setup/configuration, authentication, database responses, or specific failing endpoints?

Jumping into CI API fixes is pretty straightforward, especially if the project already has controllers and routes in place. I’ve debugged CI REST setups before — token handling, routing quirks, and MySQL queries that don’t return what the API expects. I’d start by running your existing endpoints, checking headers and auth flow, then tracing any failing controllers to clean up the logic. Quick questions: are the issues mostly auth or data output? which CI version are you on? and do you have Postman tests I can replicate? Juan Pablo

Hi, It looks like the main thing here is getting the existing REST API stable and reliable before scaling further. Most of the time these APIs start simple but get messy when real traffic or integrations come in. I’ve worked on similar REST backends before, and the part that usually needs the most care is how the routes, controllers, and database queries handle edge cases like malformed requests or timeouts. One example was setting up proper error responses and logging for an API that later handled a few thousand daily calls without issues. I’d start by mapping the current endpoints, checking the database schema, and adding basic validation and error handling. Then I’d set up a simple test suite to catch regressions. The biggest unknown is usually how the API interacts with the rest of the system—whether there are hidden dependencies on specific server configurations or third-party services. If you have any existing Postman collections or endpoint docs, that would help speed things up. Thanks, Denis
