# topup_in_progress (409)

A top-up for this asset is already open and part-paid.

## Cause

A crypto top-up quotes an amount at a price that is locked for the life of
that quote. Whatever the market does while the transaction confirms, the payment
is credited at the price shown when it was made.

A deposit address is permanent and belongs to the account. Two open quotes for
one asset would leave a payment arriving there with two locked prices claiming
it. While a quote has nothing against it, asking for a new one replaces it. Once
part of the payment has arrived, the open quote is carrying money settled at its
price, and it is not replaced.

## The message

```text
A top-up for this asset has already been paid in part; it is settled at the price it locked.
```

## The fix

Finish the open top-up, or wait for its window to close and then create a new
quote. Sending the rest of the quoted amount to the same address credits it at
the same price.

Money already sent is never lost by waiting: a payment that arrives late is
still credited, at the price the quote locked.

## event_id

`event_id` is always `null` on this code. It is a refusal the caller is meant
to handle, so nothing is recorded as a failure to look at. The service answers
and writes one log line.
