Why was my payment declined?

Most declines come from your card issuer or an unfinished bank verification step and the decline code shown on your billing page tells you which. The most common ones:

Decline code	What it means	What to do
`payment_intent_authentication_failure`	The 3D Secure / OTP step wasn't completed.	Finish the bank prompt and retry.
`card_velocity_exceeded`	Your card hit a transaction or spending limit.	Contact your issuer or use another card.
`stop_payment_order` / `revocation_of_all_authorizations`	Your bank was told to stop the charge.	Ask them to reverse it, or use a different card.
`generic_decline` / `do_not_honor` / `insufficient_funds`	Your bank declined it.	Contact them or try another card.
`processing_error`	A temporary glitch.	Just retry.

Make sure your billing details match what your bank has on file, and that the card allows online/international payments.
