I will troubleshoot rest API errors and webhook integration issues
Marlon M
About this gig
Is an API returning an error, a webhook failing, or JSON arriving in the wrong format? I will investigate one specific integration problem and explain the next step.
I bring 20 years of software development, architecture and DevOps experience.
BASIC: Review one failed request or webhook, a sanitized response and the relevant API documentation. Receive findings and a corrected request example where the documentation supports one. Code implementation is not included.
STANDARD: Fix one agreed request or webhook issue in an existing integration. Includes changed source files and test notes.
PREMIUM: Integrate one documented REST endpoint into one existing application, using an existing authentication setup, with basic error handling and handover notes.
Message me on Fiverr with the stack, API docs and error before ordering so I can confirm compatibility. Use test credentials through an agreed secure method; never paste live secrets into the brief.
Paid API fees, full backends, custom OAuth systems, new payment flows, bulk data migration and ongoing support are excluded. Revisions cover the agreed endpoint only.

FAQ
Does the Basic package include implementation?
No. Basic covers the diagnosis and written deliverables stated in the package. Code implementation requires a separately agreed scope. You are not required to purchase more work.
What does a revision cover?
A revision corrects the delivery against the originally agreed issue. It does not add features, new issues, new environments or ongoing support.
Do you need production passwords?
Start with sanitized logs and a minimal reproduction. Use test data and limited, temporary access only when needed. Never put secrets in public files or the order brief.
Which APIs and languages do you support?
Send the API documentation, stack and error on Fiverr before ordering. I will confirm compatibility and scope. A public or documented REST API and a reproducible test case are needed.
