A package of classes to support payment, financial, securities & accounting message generation (for ISO 20022 messages).
These are the type of payments messages used in payment schemes such as FedNow, FedWire, TARGET2, CHAPS, CBPR+, MEPS+ and other SWIFT/Wire Transfer style payments etc. You may hear them refered to as PACS messages (but there are others types as well, like CAMT.056 or PAIN.001 or ADMI.004 etc).
You might use these messages if you intitate payments from your company into a larger financial institution, in this scenario you will be generating PAIN (thats Payment Initiation) messages.
See a full list of types and versions here.
(Raise an issue in github if find a version or msg type is missing! We are constantly expanding the scope of messages we support.)
Install this package and some others...
pip install pyiso20022
pip install xsdata[cli,lxml,soap]Then use this code to parse a PAIN message, like this one.:
from xsdata.formats.dataclass.parsers import XmlParser
from pyiso20022.pain.pain_001_001_08 import *
import sys
parser = XmlParser()
# Read in a file, you can get an example PAIN (Payment Initiation) message from:
# https://developer.gs.com/docs/services/transaction-banking/pain001sample/
with open("example_files/gs_pain/pain001_001_08.xml", "rb") as xml_file:
doc: Document = parser.parse(xml_file, Document, )
# Print out the Post Code.
print(doc.cstmr_cdt_trf_initn.pmt_inf[0].dbtr.pstl_adr.pst_cd)or...
Use this code to create a PAyment INitiation message. We've used pain.001.001.08 but other versions are available.
It will create a file called: my_pain_001_001_08_from_code.xml

This is an example of how to create a realistic PACS.008 MX payment message.
(it should write out a file called: my_pacs_008_from_code.xml)
Depending on your setup you may need a different or even no wrapper element (We've used <MSGRoot> here, but yours might be called something different etc)

Currently this will extract the Ntry list and take all details and place them into seperate columns. It will also translate the element names into their more meaningful English versions.
Use it like this:
import pyiso20022.tools as isotools
isotools.camt053_to_excel("my_camt053_file.xml",
"my_camt053_excel_file.xlsx")And you'll get something like this when you open your Excel file:
Currently pyiso20022 supports PACS, PAIN, ADMI and CAMT messages as well as HEAD (header documents for the messages).
