merchant.py is a daemon that manages payments for a web server. It
|
||||
creates Bitcoin addresses using a master public key (so you do not
|
||||
leave your private keys on the server), detects when payments are
|
||||
received and notifies your web application.
|
||||
|
||||
The workflow goes like this:
|
||||
|
||||
- the server sends a request to the daemon via POST. the request
|
||||
contains an amount to be paid, a number of confirmations, and an
|
||||
expiration period in hours.
|
||||
|
||||
- the daemon answers with a Bitcoin address, where the customer needs
|
||||
to send the coins.
|
||||
|
||||
- later, the daemon will send a POST to the webserver, to notify that
|
||||
the payment has been received OR that the request has expired
|
||||
|
||||
|
||||
Since addresses are generated using an Electrum master public key, it
|
||||
is possible to visualize payments in the Electrum client; you will,
|
||||
however, need to manually adjust your "gap limit".
|
||||
|
||||
In order to use this script, first edit and rename
|
||||
merchant.conf.template to merchant.conf
|
||||
|
||||
to launch it, type:
|
||||
> python merchant.py
|
||||
|
||||
In another terminal, you may send a request from the command line (it
|
||||
will send the request to the running daemon via http). For example,
|
||||
here is a request for 0.1 bitcoins, that requires two confirmations,
|
||||
and expires in 120 minutes:
|
||||
|
||||
> python merchant.py request 0.1 2 120
