A previously vaulted payment method can be deleted by calling the DELETE /payment-methods/{payment_method_id} API.
This API does not delete the stored payment method from any of the underlying payment services.
curl -i -X DELETE "https://api.example.gr4vy.app/payment-methods/77a76f7e-d2de-4bbc-ada9-d6a0015e6bd5" \
    -H "Authorization: Bearer [JWT_TOKEN]"
The API returns an empty response once the payment method was deleted.
