Summary	0005873: design document and implement "legacy" banking API for libeufin and implement wirewatch plugin
Description	Some banking APIs do not offer us nice, monotonically increasing transaction identifiers. Instead, we can only query a time range of transaction data. Even worse, new transaction might appear in a time range that we've already queried, so we need to re-query older time ranges, preferably with a lower frequency than querying the newer ones. With libeufin, we will have a unified interface to query these "legacy" bank interfaces. However, this still doesn't give us a "nice" transaction history like the Taler demo bank gives us. To allow integration with legacy APIs, we need to 1. Define a HTTP/JSON API between the wirewatch plugin and libeufin for "legacy bank interfaces" 2. Implement a wirewatch plugin for this 3. Implement a "legacy bank interface" for our own demo bank, so we can test the wirewatch plugin.

Marcello Stanisci 2019-09-04 09:55 reporter ~0014853	Point number 3 was implemented a while ago (but of course never tested due to the lack of a wire-plugin)! https://docs.taler.net/core/api-bank.html#get--history-range

Florian Dold 2020-01-07 16:39 manager ~0015237	This bug report still refers to the old design of libeufin. In the new design, the libeufin nexus service provides a cleaned up transaction history to the exchange.
