Endpoint
| Endpoint | Method |
|---|---|
/api/admin/carts/{cartId}/payment-methods | POST |
Sequence
Items + addresses + shipping method must be present. Otherwise the response is HTTP 409 with a precise message identifying the missing step.
Note on supported methods
For POST /api/admin/orders/place/{cartId} to succeed, the saved method must be one of cashondelivery or moneytransfer (matches the admin Create-Order screen). This endpoint will save any supported method, but place-order returns HTTP 422 for any other choice.
