Before you write
A good ticket is answered in one reply. Include these and support gets everything it needs up front:
What to include
Your account email or username, the checkout or payment URL, the coin and amount, and the transaction hash if a payment is involved. For integration questions, the request you sent and the response you got.
Self-serve first
Many answers live in the troubleshooting guide and the webhook docs. The REST API reference documents every endpoint, and two-factor login issues have their own page.
Bugs pay bounties
U.CASH Pay + AI is in public beta: open a support ticket for a suggestion or a bug and it can earn a bounty. Concrete reproduction steps (what you did, what you expected, what happened) make it actionable immediately.
