Python Visma Administration

API for Visma Administration 200/500/1000/2000.

Visma has added support for a 64-bit API in version 2023.1. Therefore, this package aims to be compatible with both 32-bit and 64-bit versions to maintain backward compatibility. The AdkNet4Wrapper is loaded on 32-bit Python installations, and AdkNet6Wrapper is loaded on 64-bit Python installations.

Writing integrations for Visma's API often involves extensive boilerplate code. This package aims to present the API with a user-friendly, Pythonic interface, and make it more accessible. It's not feature complete, but it covers most basic needs, and you can tap into the underlying C# API if needed.

Installation

pip install visma-administration  

Usage

Add companies that you would like to access data from

from visma_administration import Visma
Visma.add_company(name="FTG10", common_path="Z:\\Gemensamma filer", company_path="Z:\\Företag\\FTG10")

# You can then access specific companies with a context manager
with Visma.get_company_api("FTG10") as api:
	pass

CRUD Operations

Read a single record

with Visma.get_company_api("FTG10") as api:
    record = api.supplier_invoice_head.get(adk_sup_inv_head_invoice_number="number")
    print(record.adk_sup_inv_head_invoice_number)

Update a record

with Visma.get_company_api("FTG10") as api:
    record = api.supplier_invoice_head.get(adk_sup_inv_head_invoice_number="number")
    record.adk_sup_inv_head_invoice_date = datetime.now()
    record.adk_sup_inv_head_vat_amount = 5000
    record.adk_sup_inv_head_paymstop = True
    record.adk_sup_inv_head_supplier_name = "Name"
    record.save()

Create a record

with Visma.get_company_api("FTG10") as api:
    new_record = api.supplier.new() # new method is called
    new_record.adk_supplier_name = "Nvidia"
    new_record.save()

Delete a record

with Visma.get_company_api("FTG10") as api:
    john = api.supplier.get(adk_supplier_name="John")
    john.delete()

Get multiple records

with Visma.get_company_api("FTG10") as api:
	invoices = api.supplier_invoice_head.filter(adk_sup_inv_head_invoice_number="f03*")
	total_sum = sum(invoice.adk_sup_inv_head_total for invoice in invoices)
	print(f"Total for all invoices with invoice_number starting as 'f03' is: {total_sum}")

	# filter returns a generator, so you can limit how many items to return
	import itertools  
	suppliers = api.supplier.filter(adk_supplier_name="*N*")  
	suppliers = itertools.islice(suppliers, 5)  
	for supplier in suppliers:  
		print(supplier.adk_supplier_name)  

Working with rows Existing rows can be accessed with: .rows() and creating new ones by calling .create_rows()

with Visma.get_company_api("FTG10") as api:
	# lets create a new invoice and add rows
	invoice = api.supplier_invoice_head.new()
	invoice.adk_sup_inv_head_invoice_number = "50294785"
	
	# Creates 3 row objects
	rows = invoice.create_rows(quantity=3)
	rows[0].adk_ooi_row_account_number = "5010"
	rows[1].adk_ooi_row_account_number = "4050"
	rows[2].adk_ooi_row_account_number = "3020"
	invoice.save()
	# We now have a new invoice with 3 rows.

	# Here we can access existing rows
	for row in invoice.rows():
		print(row.adk_ooi_row_account_number)
	
	# Delete last row
	# If you would like to delete more than one row,
	# Check the Deleting multiple rows section of the README
	invoice.rows()[-1].delete()
	
	
	

Deleting multiple rows

After .delete() is called on a row, Visma automatically reassigns new indexes to every row, therefore according to their documentation, you have to request all rows again to continue working with them.

# If you would like to delete all custom rows, use the code snippet below.
# You have to start deleting them by negative index, since templates
# will automatically readd rows depending on your configurations
nrows = invoice.adk_sup_inv_head_nrows  
for i in range(int(nrows)):  
  invoice.rows()[-1].delete()

Other info

In Visma's documentation you can find a list of DB_fields that you may access through their API.
For instance

ADK_DB_PROJECT  
ADK_DB_ACCOUNT  
ADK_DB_SUPPLIER 

You can access these fields directly from your instantiated Visma API object,
ADK_DB_ is removed and the name is lowercased.

For example:

with visma.get_company_api("company") as api:
    api.supplier  
    api.account  
    api.project  

These DB_Field attributes returns an object from which you can request data

api.supplier.get()  # returns a single object or returns an error  
api.supplier.filter()  # returns multiple objects  
api.supplier.new()  # Gives you a new record  

Both get and filter accepts filtering on a field as argument. You pass the field name which you want to filter upon, and a valid filter expression ( Visma have documentation for this. You can filter on multiple fields by just passing multiple filter expressions

"""
This filters on the ADK_SUPPLIER_NAME field of ADK_DB_SUPPLIER
*text* is a valid filter expression which returns a result with inc anywhere inside of the name
Refer to Visma documentation for further information on how to form different types of filter expressions.
"""
result = api.supplier.get(adk_supplier_name="*inc*")

Consider whatever get, filter and new returns to be database record(s). These records have fields associated with them, if you check documentation for ADK_DB_SUPPLIER, you can find a whole bunch of fields associated with it.

ADK_SUPPLIER_FIRST
ADK_SUPPLIER_NUMBER
ADK_SUPPLIER_NAME
ADK_SUPPLIER_SHORT_NAME
... And a lot more

These fields are mainly used in two ways,

test = api.supplier.get(adk_supplier_name="test")  # Used when filtering
test.adk_supplier_name = "test1"  # Or used when interacting with a supplier record

Visma has to be installed on the PC you import the package on. Either full client or integration client is fine.
