14.9.2. Synopsis

libeufin-nexus [-h | –help] [–version] COMMAND [ARGS…]

Subcommands: dbinit, ebics-setup, ebics-submit, ebics-fetch, serve, initiate-payment, manual, config

14.9.3. Description

libeufin-nexus is a program that provides a service to interface to various bank access APIs

Its options are as follows:

-h | –help

Print short help on options.

–version

Print version information.

The interaction model is as follows:

• Configure the database with commands dbinit.

• Setup EBICS access with commands ebics-setup. Setting the access means to share the client keys with the bank and downloading the bank keys

• After a successful setup, the subcommands ebics-submit and ebics-fetch can be run to respectively send payments and download the bank account history.

• Start the HTTP server with command serve. Let this run in a shell, writing logs to stderr.

The following sections describe each command in detail.

14.9.3.1. dbinit

This command defines the database schema for LibEuFin Nexus. It is mandatory to run this command before invoking the ebics-setup or serve commands.

Its options are as follows:

-c | –config config_file

Specifies the configuration file.

-L | –log LOGLEVEL

Configure logging to use LOGLEVEL.

-r | –reset

Reset database (DANGEROUS: All existing data is lost)

-h | –help

Print short help on options.

14.9.3.2. ebics-setup

This command creates the client keys, if they aren’t found already on the disk, and sends them to the bank if they were not sent yet. In case of sending, it ejects the PDF document that contains the keys fingerprints, so that the user can send it to the bank to confirm their keys. The process continues by checking if the bank keys exist already on disk, and proceeds with downloading them in case they are not. It checks then if the bank keys were accepted by the user; if yes, the setup terminates, otherwise it interactively asks the user to mark the keys as accepted. By accepting the bank keys, the setup terminates successfully.

It is mandatory to run this command before invoking the ebics-fetch or ebics-submit commands.

Its options are as follows:

-c | –config config_file

Specifies the configuration file.

-L | –log LOGLEVEL

Configure logging to use LOGLEVEL.
