It is necessary to complete three tasks in the OpenCart module.

Budget: 8000 UAH Deadline: 5 days

Hello.
I have practical experience working with the Facebook API (Graph API), Webhooks, and OpenCart (custom modules, PHP). I have worked with loading messages/comments, processing webhook events, saving data to the database, and fixing synchronization logic.

I have reviewed the task description in Google Docs — the scope and logic are clear.

1) Total cost for 3 tasks: 8,000 UAH
2) Implementation period: ~5 days
3) When I can start: I can begin immediately after agreeing on the terms

I work carefully with live integrations, with logging and checking webhook events, without "breaking" production.
I am ready to answer clarifying questions and quickly get to work. Expand

Hello. I have experience with Facebook API and OpenCart. I am ready to collaborate. Please contact me.

Hello.
I have reviewed the module description and all three task blocks.
To the point: in its current form, this is a custom integration of OpenCart with Facebook / Instagram (Graph API, Webhooks, OAuth, cron). Some issues may be caused by changes on the Facebook API side, while others may stem from the logic of the module itself. It is only through a preliminary technical analysis that we can correctly separate code errors from external limitations or API changes.
Therefore, I suggest starting with a separate stage 0 (technical analysis).
---
As part of the analysis, I will check:
1. Comments and Webhooks
— active Webhooks subscriptions (objects, fields, Graph API version);
— whether comment / mention events are actually reaching;
— whether the payload has changed and if it is being processed correctly by the module;
— why direct messages work while comments do not.
2. "Stuck" messages and button errors
— the logic of status changes in the database;
— requests to the Graph API during delete / close;
— actual API responses and errors (permissions, expired token, invalid object);
— the reason why the status does not change after actions in the interface.
3. OAuth and tokens (disruption after ~60 days)
— what types of tokens are used;
— whether the correct token exchange is performed;
— the binding of tokens to App ID / App Secret;
— what changes are needed in the account addition code to enable automatic updates.
4. Cron token updates
— analysis of the proposed script;
— what can be used without changes and what needs to be adapted for the module;
— risks of rate limits and blocks.
5. Indication of new messages (SSE)
— the feasibility of using SSE in the OpenCart admin panel;
— load and stability;
— correctness of the "unread" logic.
---
After the analysis, you will receive:
— a clear conclusion on each point (what broke and why);
— a list of what can realistically be fixed within the API;
— a confirmed plan for changes in the code;
— a realistic assessment of timelines and implementation costs;
— separately marked limitations that cannot be bypassed without changing the architecture.
Until the completion of stage 0, I will not fix final timelines and budget to avoid unexpected revisions during the process.
---
To start the analysis, I need:
— access to the module code;
— access to the OpenCart admin panel;
— data for the Facebook App (App ID, mode, permissions);
— if possible, logs of webhooks or errors.

If this format works for you, we can start with stage 0. Expand
