Wise Statements Viewer

The Wise statements viewer is a streamlit app, which displays Wise account statements. The app is built using Wise's API. Its functionality is designed for a specific use case:

• Business accounts only.
• Both standard accounts and Jar accounts (if they exist).
• EUR currency only.
• The date output is formatted in the European standard: dd.mm.yyyy.

However, the code can easily be modified.

App Description

Authentication

In order to link the app with Wise, you must first create an API token with your account. Then you must create public and private keys and register them with your Wise account. Refer to the authentication instructions below if you are not familiar with this process.

Using the app

Once the app is running in your browser (see the Installation instructions below), you must link it to your account:

1. On the left sidebar, enter your API token.
2. Under "Upload private key file," click the "Browse files" button, and select your private key file.

• Note: if you set WISE_API_TOKEN as an environment variable, the app will automatically use this token. Only the 'Upload private key file' field will be displayed.

And that's it! Once you are linked to your account, the side panel will show four pages:

Statement Pages:

If one of the "statement" pages is selected, the main field will display a choice of start and end date (yyyy/mm/dd) for the statement you would like to view:

The default start and end dates are 30 days prior and the current date, respectively. While navigating the statement pages, your choice of date range will be preserved. If you navigate to the metadata page, the date range will reset.

For each statement page, a dataframe will be displayed for the selected date range, and two buttons are displayed to download the dataframe as either a CSV or an Excel file:

Some dataframe comments:

• For the standard and for the jar accounts, the page displays a full statement dataframe.
• For the cashback payment, a dataframe is displayed for all Wise cashback payments with jar and standard account transactions both included. Wise's cashback transactions are subject to a tax withholding, with a rate of 30% at the time of this writing. The full tax withheld amount for each transaction is displayed in the dataframe, along with a total tally in the last row.

Metadata Page

The fourth page displays the JSON-formatted metadata for the account:

• Profile metadata: account type, address, creation date, etc.
• Standard account balance metadata: currency, account number, balance, etc.
• Jar account balance metadata (same)
  • If a jar account does not exist, an empty {} will be displayed.

Comments:

• If you would like to test the app using a sandbox account, you must enable the sandbox API endpoints by clicking the "sandbox account" checkbox in the top left corner:

• If you have multiple business accounts with the EUR currency, only the first one listed in the metadata will be displayed.
• The API endpoints for the cashback information and the account metadata do not require Strong Customer Authentication (SCA). As a result, if you enter your account's API token, but an incorrect private key file, the get command running in the app will not throw an error. Hence the last two pages will be generated successfully.
• If you have a WISE_API_TOKEN set as an environment variable, you can run the app without entering the token each time.

Developer Note

For any developers who would like to make edits, note that all generations of the application's interface and main functionality are centralized within the app.py file. All interactions with the Wise API, including data retrieval and processing, are managed in the wise.py file. Developers interested in understanding or contributing to the application's core functionality or its API integration are encouraged to review these specific files for detailed insights into the implementation.

Authentication Instructions

The following are instructions you can follow for creating an API token and public/private keys for Wise.

1. Create an API token with Wise:

   • Go to Wise and log in to your account.
   • Go to Settings > API tokens > Create a token.
   • Store the token in a secure location on your computer. Consider using a password manager or encrypted storage.

2. Create a public and private key. In a terminal (Linux/macOS) or Command Prompt/PowerShell (Windows), do the following:

   • All users: create the directory in a secure location on your computer:
     • mkdir YOUR_DIRECTORY
     • navigate to the directory: cd YOUR_DIRECTORY
   • Linux/macOS:
     • openssl genrsa -out YOUR_FILENAME-private.pem 2048
     • openssl rsa -pubout -in YOUR_FILENAME-private.pem -out YOUR_FILENAME-public.pem
   • Windows:
     • Ensure OpenSSL is installed on your computer. If not, you can download it from here, or a package manager.
     • Use the same commands as above in your PowerShell or Command Prompt. You might need to specify the full path to the OpenSSL executable if it's not added to your PATH environment variable.

3. Register public key with Wise

   • Log in to your Wise account, then navigate to Settings > API tokens > Manage public keys. Add the file YOUR_FILENAME-public.pem.
   • Follow any on-screen instructions to complete the registration.
