Since 2013, I have been collaborating with TravelPayouts. Payments come regularly, overall, everything is quite good, but this affiliate program has both positive and negative sides. The pros include: • a modern interface • high conversion rates • good commissions • convenient search and various tools for webmasters • the ability to export data via API. As for the cons: • extremely slow statistics!!! • several times, hotel sales were not accounted for, even though I definitely made purchases myself! I contacted customer support, the issue was resolved, but my trust was slightly shaken(((
