I will integrate and fix PHP rest apis
Phuc Nguyen
About this gig
I focus on the full integration flow, not just the API request itself. I trace authentication, payloads, backend logic, database updates, webhooks, and failure cases so the integration works reliably inside your application.
This helps reduce repeated debugging, broken data flows, failed callbacks, and integration-related rework.
Please message me before ordering if the API is undocumented, requires multiple systems, or the scope is unclear.

FAQ
What do you need from me to start?
Please provide the API documentation, your integration goal, relevant source code or access, authentication method, and any current errors or failed requests.
Can you integrate third-party REST APIs into an existing PHP application?
Yes. I can integrate REST APIs into custom PHP, Laravel, CodeIgniter, Symfony, and other existing PHP applications.
Can you fix an API integration that is already implemented but not working?
Yes. I can trace authentication, requests, responses, webhooks, database updates, and application logic to identify and fix the root cause.
Do you work with OAuth, JWT, API keys, and webhooks?
Yes. I can work with common API authentication methods and webhook or callback workflows when supported by the provider.
Does one package include unlimited APIs or endpoints?
No. Each package covers the defined scope of one integration or workflow. Multiple APIs, large endpoint sets, or complex systems may require a custom offer.
Can you work with an API that has little or no documentation?
Sometimes. I can inspect existing requests, responses, SDKs, network behavior, sample payloads, or legacy integration code to understand the API. If the provider blocks access or exposes no usable interface, I will explain the limitation before proceeding.
