Developer on Next.js
Need to refine the service: set up proper login verification through Google, Facebook, TikTok. Currently, errors are being issued.
In fact, the integration exists but works only with the test accounts where the integration was created.
Only write if you have experience with login integrations through Google, Facebook, TikTok. I will describe in more detail the execution that interests me.
Be sure to indicate your rate.

I can take this on. My rate is 1500 UAH per hour, and for this task, I would estimate around 6-10 hours after a brief diagnosis. If the problem is only with the OAuth settings, redirect URI, scopes, application mode, or production access - this usually takes 1-3 days.
Look, there’s a nuance here... the fact that the login works only with test accounts is very similar to applications in Google, Meta, or TikTok that are not fully set up for production, or to different environments for local and production settings. We will need to check the Next.js code, callbacks, domains, environment variables, and application statuses in the providers' dashboards.
> Question 1 - is your authorization done through NextAuth/Auth.js, Firebase, Supabase, or a custom implementation?
> Question 2 - do the errors appear after selecting an account, on the callback page, or at the stage of opening the provider's window?
We have experience in services with authorization, integrations, and business logic, where stability is important, not just logging in somewhere once =)

> https://business.ingello.com/forma-crm - an example of a corporate system where access, rights, and process reliability are important
> https://systems-fl.ingello.com/ua - briefly about our approach to complex web systems
So here’s the thing - I would first conduct a technical diagnosis, then provide a precise list of causes and fixes. But we can keep it simple; if everything hinges on the providers' settings - we’ll close it quickly.

Hello, Website-Studio!
To understand the situation in detail, please clarify:
1. What specific errors occur during the login verification?
2. Is there access to the server logs to analyze the causes of the errors?
3. Will it be necessary to check/modify the existing backend in PHP?
4. Are there specific requirements for the user interface during login?
My approach to work:
… First, I analyze the current integration settings to identify the causes of the errors. Then, I check the correctness of the API configurations from Google, Facebook, and TikTok. After that, I optimize and test the verification on real accounts to ensure it works not only with test accounts.
As a result, you will receive a stable login integration without errors that works with any accounts.
Please provide your clarifications so I can offer an accurate estimate of the cost and timeline.

Hello, Arthur! The situation where authorization through Google, Facebook, and TikTok works only with test accounts, while in production it gives errors, is usually related not to the integration itself, but to the OAuth settings: redirect URI, application mode (test/live), access restrictions, or incorrect scopes. Because of this, login works only in the "allowed" test environment and fails for real users.
To better understand the cause, I need to clarify:
- What is the authorization implemented on — NextAuth or custom OAuth logic?
- When exactly did the problem arise — immediately after deployment or after connecting a specific provider?
- What specific errors do you see when logging in?
What I propose: I will audit all three OAuth integrations, check the application configurations and redirect URIs, align the behavior between dev and production, and resolve discrepancies that break the authorization. After that, I will test the login on real accounts to ensure that the problem is completely resolved and will not recur in the future. My rate starts at $20/hour, depending on the type of task.
…
I suggest we discuss the details!

I was setting up OAuth integrations (Google, Facebook) on Next.js — a typical reason for the issue: the app did not pass verification with Meta/Google, so it only works with test accounts. For TikTok, there is a separate app verification process as well.
I will fix the OAuth console settings, redirect URI, scopes, and will go through the verification of production apps. Rate — 600 UAH/hour, approximately 3-5 hours depending on the state of the current configurations.
What is the backend platform — Next.js API routes or a separate server?

Hello, I worked on integrating Google/Facebook login for an e-commerce platform with over 15,000 users, where I set up OAuth for the production environment and fixed similar issues with test accounts, achieving 95% successful authorizations.
Do I understand correctly that the problem is that the OAuth applications are not configured for the production domain, or are there restrictions in the App Review settings for Facebook/TikTok?
I suggest we connect; I will provide you with free technical consultation and we can create a development plan + I will tell you about my team! ✨

I already have a practically ready similar solution for logging in through OAuth providers, which can be quickly adapted to your Next.js service and discussed right here and now, I'm available =)
!! Rate - 900 UAH per hour !!
Estimated first stage - 12,000 UAH, 3 days.
So here’s the thing - I would simplify it, first checking the app settings in Google, Facebook, and TikTok, domains, redirect addresses, environment variables, and token verification logic in Next.js, and then I would get the login to work for non-test accounts.
It seems that the integration currently only works for test accounts due to the providers' development mode, incorrect permissions, or incorrect callback URLs.
The question is - what is the authorization currently built on - NextAuth/Auth.js, Firebase, or a custom scheme?
And also - do you have access to the dashboards of Google, Facebook, and TikTok where the apps were created?

Hello. The issue with test accounts for Google, Facebook, and TikTok usually indicates an incorrect redirect URI in the production environment or a non-public status of the OAuth application. Facebook and TikTok are particularly strict about this. Last year, I fixed something similar for a marketplace - there, TikTok rejected the login from a domain that was not added in "Valid OAuth Redirect URIs," even though it worked in dev. Google often complains about "Authorized domains" vs the actual host. What is your authorization stack - NextAuth.js, Clerk, or a custom implementation? And do you have access to the developer consoles of all three platforms?
