I will fix broken API integrations in PHP or laravel
Christian H
About this gig
Do you have a PHP or Laravel API integration that stopped working, returns errors, sends wrong data, or no longer connects to a third-party service?
I help fix existing API integrations in PHP and Laravel applications. This includes REST APIs, authentication issues, failed requests, broken webhooks, response handling, data mapping problems, and backend errors around external services.
I work on existing production systems with a practical focus: reproduce the issue, find the real cause, make a clean fix, and document what was changed.
Relevant experience: PHP backend development since 2012, Laravel, Symfony/Lumen, MySQL, REST APIs, reporting API integrations, backend maintenance, and stabilization of existing web applications.
Before ordering, I need a clear issue description, access to the relevant code, API documentation, logs or error messages, and test credentials if the API requires authentication.

FAQ
Can you fix any API integration?
Only if the issue is reproducible and I have enough access to inspect the code, logs, API documentation and credentials. If the API problem is unclear, I will first investigate the cause before changing code.
What do you need before starting?
I need a clear description of the issue, access to the relevant PHP or Laravel code, API documentation, error messages or logs, and test credentials if authentication is required.
Do you work on live production systems?
Yes, but changes should be tested safely before deployment. I prefer working with a staging environment, repository access and a clear way to verify that the API integration works again.
