Getting started

 

 

Get started with receipt parsing in python.

 

1. Install the mindee python helper library

 

Install from PyPi using pip, a package manager for Python.

 

pip install mindee

 

Don't have pip installed? Try installing it, by running this from the command line:

 

$ curl https://bootstrap.pypa.io/get-pip.py | python

 

Getting started with the Mindee API couldn't be easier. Create a Client and you're ready to go.

 

 

 

2. Instantiate your Client

 

The mindee.Client needs your API credentials. You can either pass these directly to the constructor (see the code below) or via environment variables.

 

Depending on what type of document you want to parse, you need to add specifics auth token for each endpoint.

 

from mindee import Client

mindee_client = Client(
    expense_receipt_token="your_expense_receipts_api_token_here",
    raise_on_error=True
)

 

  • expense_receipt_token: (string) API key for expense_receipts endpoint
  • raise_on_error: (boolean, default True) Specify wheter or not raising an Exception when HTTP errors occur. If set to False, when calling the parse_receipt method, the Response.receipt object returned will have be set to None and the  Response.receipts list will be empty.

 

 

We suggest storing your credentials as environment variables. Why? You'll never have to worry about committing your credentials and accidentally posting them somewhere public.

 

 

 

3. Parse a receipt

 

Using the parse_receipt method from your client object, you can pass any image or pdf file to get the receipt data.

 

from mindee import Client

mindee_client = Client(
    expense_receipt_token="your_expense_receipts_api_token_here",
    raise_on_error=True
)

parsed_data = mindee_client.parse_receipt("/path/to/file")

 

 

Input types

 

You can pass your input file in three ways:

 

From file path

receipt_data = mindee_client.parse_receipt('/path/to/file', input_type="path")

 

 From a file object

with open('/path/to/file', 'rb') as fp:
     receipt_data = mindee_client.parse_receipt(fp, input_type="file")

 

From a base64

receipt_data = mindee_client.parse_receipt(base64_string, input_type="base64")

 

 

receipt_data structure

 

The receipt_data object returned by the parse_receipt method contains the following elements:

 

receipt_data.receipt

 

The receipt attribute is the Receipt object constructed by gathering all the pages into a single document. The method used for creating a single receipt object with multiple pages relies on fields confidence scores. Basically, we iterate over each page and for each field, we keep the one that has the highest probability.

 

receipt_data.receipt # returns a unique object from class Receipt

 

 

receipt_data.receipts

 

For multi pages pdf, the receipts attribute contains one receipt object per input. For a single-page pdf or an image, the list will only contain 1 item, and for multi-page pdf, it will contain one item per page.

 

receipt_data.receipts # [Receipt, Receipt ...]

 

 

receipt_data.http_response

 

Contains the full Mindee API HTTP response object in JSON format

 

receipt_data.http_response # full HTTP request object

 

 

 

4. Display the results

 

You only have to print your receipt object to display the different extracted fields:

 

from mindee import Client

mindee_client = Client(
    expense_receipt_token="your_expense_receipts_api_token_here",
    raise_on_error=True
)

receipt_data = mindee_client.parse_receipt("/path/to/receipt")

print(receipt_data.receipt)
