card_verification_required

HTTP 402 A payment card must be linked before paid resources can be created

What happened

Creating a paid resource is refused because the owner of this project has no payment card linked. Reading, deleting, and any change that lowers your spend are unaffected.

What to do

Link a payment card in the Client Area, then send the same request again with a NEW Idempotency-Key. Reusing the earlier key replays the stored refusal for up to 24 hours instead of trying again; the request body itself does not need to change.

Retrying

Change the state this refers to, then repeat the same request with the same idempotency key.
