Automated Donor Rank Integration

I already run a phpBB forum with a working rank structure. What I’m missing is a bridge between the site where people donate or vote and the forum itself.

Here’s what I need the new function to do:

• Donations
– As soon as a user donates, add the “Donor” rank to the matching phpBB account.
– Keep a running total; once that user reaches USD 25 in cumulative donations, swap or upgrade them to a “Special Donor” rank automatically.

• Voting
– Track vote counts per user on the website.
– After 10 successful votes, assign the “Voter” rank in phpBB.

Key points:
– The forum already handles ranks, so your work is purely the automation layer.
– You may hook into whatever CMS and payment gateway are in place; I can expose the needed endpoints or database tables.
– The code should run quietly in the background (cron or webhook is fine), log its actions, and gracefully handle failed look-ups or mismatched usernames.
– I’d like clear setup instructions so I can re-deploy the script on future updates.

If you’ve integrated phpBB with external systems before, this should be straightforward. Looking forward to a clean, lightweight solution that won’t require major changes to core files.

hope for a low budget as possible
