Resolve OpenAI API Payment Failure

I keep running into a transaction failure each time I try to make a one-time purchase of credits through the OpenAI dashboard. The payment never even leaves the “Pay now” screen—nothing is charged, and no confirmation email arrives—so the problem seems to stop right at payment initiation.

I’m looking for someone who already knows the ins and outs of OpenAI’s billing flow (Stripe console, webhooks, card verification rules, 3-D Secure, etc.) and can walk me through what’s going wrong and how to fix it. Whether the solution involves correcting account settings, providing the right payment metadata, or liaising with OpenAI support, I’d like clear, actionable guidance so I can complete the purchase without errors.

Deliverables
• A concise diagnosis of why the payment is blocked
• Step-by-step instructions or screen-share assistance to resolve the issue
• Proof that the transaction goes through (screenshot or dashboard confirmation)

Acceptance will be based on my ability to buy credits successfully after following your guidance.
