Step-by-step guides for the most common problems.
Free to start. No card. No surprises.
Tell us what you need in your own words. It takes a minute.
Meet a verified developer on video and talk it through. Free, no commitment.
The developer proposes a fixed price for the result, never an hourly rate. You can always say no.
Yes. A developer will go through what Codex changed, find what broke and get it working again. Post a task describing what happened and they will call you to look at it live.
Often, yes. An error such as token_exchange_failed usually comes from a network, proxy or settings problem on your computer, and a developer can find the cause on a call. Our step-by-step guide on that error lists the common causes.
Yes. A review is a task like any other: a developer reads what Codex built and tells you what to fix before real users arrive, such as exposed keys, missing checks on who can see what, and fragile spots.
Yes. The 15-minute call is free, with no card and no catch. If the developer solves it on the call, you pay nothing.
The developer proposes one fixed price for the result, never an hourly rate, and you can say no at no cost. You are charged only after you approve the finished work.
A verified developer usually claims your call within hours. Most things get sorted on the call itself, and for bigger work the developer has 3 days to deliver it.
Tell the developer in the chat, or report a problem and an admin decides. You aren't charged while it is open. If the developer misses the 3-day deadline, the task is reopened and nothing is charged.
Every developer is manually reviewed and approved by the platform before they can take a task.
Only what you choose to, on the call or in the chat. Nobody here will ever ask for your passwords.
Yes. Apply with your GitHub account. We review every application by hand, and once you are approved you can claim tasks from clients, set a fixed price for the work and get paid through Stripe. Join as a developer →
