Missing paypal account statements.

As per communication with PayPal this is apart from PDF and CSV reports prefered way of downloading e.x. monthly statements if you have too much and need to automate the process...

This gem provides you with simple access to specific subject account statement.

Requirements

• PayPal account of course
• Paypal credentials for NVP API can be found under:
  • Login on http://paypal.com/
  • Go to your Profile and settings (upper right corner menu)
  • Click on My selling tools
  • Under first part - Selling online - click on Update API access
  • At the bottom look up NVP/SOAP APIintegration (Classic)
  • Click Manage API credentials there
  • Finally after a while on this page is information needed for you to access NVP API data
• If you take care of multiple account data like we do, They need to give you access like this:
  • Login on http://paypal.com/
  • Click Profile“ → „Profile and settings“
  • In the menu choose „My selling tools“ and then „API access“ and click on Update
  • Choose the first option and click on „Grant API permission“
  • On the next page „Add a new third party“
  • In the new window fill in ID given to you (is the one from previous part) and click „Lookup“
  • When the ID was filled in correctly a new menu with permissions will appear („Available Permissions“).
  • Choose the following options:
    • Obtain your PayPal account balance.
    • Obtain information about a single transaction.
    • Search your transactions for items that match specific criteria and display the results.
  • Confirm the selection by clicking „Add“.

And after these couple days of setup you are all good to go :)

Important to note here is that in first part is your account and setup and stuff...

Second part is you customer (in our case) who wants you to lookup data for them and they use your id that you need to send them (is always in email like form without @ in it)

Then the subject used in search for statements is their email through which they granted API access to you...

Installation

Add this line to your application's Gemfile:

gem 'ruby_paypal_nvp'

And then execute:

$ bundle

Or install it yourself as:

$ gem install ruby_paypal_nvp

Usage

For the time being this gem provides you with Stamtement download for desired period.

The weird PayPal pagin and all things considered proven to be correct input for accountants to work with.

first step is configuration (either as initializer or if you have it in single script or so):

RubyPaypalNvp.configure do |config|
  config.user = 'YOUR_USER_HERE' # watch out may differ according to setup for sandbox
  config.password = 'YOUR_PWD_HERE'
  config.signature = 'YOUR_SIGNATURE_HERE'
  config.api_url = 'https://api-3t.paypal.com/nvp' # or put 'https://api-3t.andbox.aypal.com/nvp' for sandbox env
end

Then you are ready to query PayPal

We provide you with Statement class:

RubyPaypalNvp::Statement

Provides search method where:

RubyPaypalNvp::Statement.where(
  date_from: Time.zone.parse('1.9.2017'),
  date_to: Time.zone.parse('1.9.2017'),
  subject: '[e-mail]',
  currency: 'CZK',
  transaction_class: 'BalanceAffecting'
)

Where

• date_from beginning of interval to search for (beggining of the day - disregards time)
• date_to end of interval to search for (end of the day - disregards time)
  • Dates and times in particular are converted to utc
• subject is account email you are looking through (as per description in requirements)
• currency is as name says currency of desired account (defaults to CZK)
• transaction_class is per description found in docs (here)[https://developer.paypal.com/docs/classic/api/merchant/TransactionSearch_API_Operation_NVP/] defaults to BalanceAffecting
  • most problematic since multiple options you should be able to put the as All or Received result in 500 from PayPal which we are not able to identify (talking here about accounts with 1k+ transactions monthly)
  • default setup is provide to be stable and correct for accounting

Response you get from search is in form of Object containing:

#<RubyPaypalNvp::Model::Statement:0x007fe4360ac450
 @amount_sum=1000.00,
 @currency_code="CZK",
 @end_date="2017-09-01T21:59:59Z",
 @fee_amount_sum=10.00,
 @items=
  [#<RubyPaypalNvp::Model::Item:0x007fe43679bf90
    @amount=1000.00,
    @currency_code="CZK",
    @email="[e-mail]",
    @fee_amount=10.00,
    @name="Martin Tester",
    @net_amount=1010.00,
    @status="Completed",
    @timestamp="2017-09-01T12:48:08Z",
    @timezone="GMT",
    @transaction_id="9XXXXXXXXXXXXXXXH",
    @type="Refund">],
 @items_count=4,
 @net_amount_sum=1010.00,
 @start_date="2017-08-31T22:00:00Z",
 @subject="[e-mail]",
 @timestamp="2017-11-02T10:45:07Z">

You can see all the sums and all items which represent all movements on the account in given time period there.

Also RubyPaypalNvp::Model::Statemnt result class from query provides you method #generate_csv which will create CSV from the data for inspection:

result = RubyPaypalNvp::Statement.where(
  date_from: Time.zone.parse('1.9.2017'),
  date_to: Time.zone.parse('30.9.2017'),
  subject: '[e-mail]',
  currency: 'CZK',
  transaction_class: 'BalanceAffecting'
)
result.generate_csv('location_to_save.csv')

Another thing provided is Balance fetching, where you can ask for balance of given account at point in time when asking it... you cannot really ask for balance at given point in time, because they simply do not provide it...

For this purpose you have:

RubyPaypalNvp::Balance

it provides you again with simple .where method to ask for data:

result = RubyPaypalNvp::Balance
  .where(subject: '[e-mail]', currency: 'CZK')

Where

• subject is account email you are looking through (as per description in requirements)
• currency is as name says currency of desired account (defaults to CZK)

Result provides speak for itself:

#<RubyPaypalNvp::Model::Balance:0x007fd8f0a17f90
  @currency_code="CZK",
  @opening_balance=58221.0,
  @subject="[e-mail]",
  @timestamp="2017-12-06 10:00:14 +0100">
