Automatic document field detection API

Import invoices provides a robust suite of APIs designed to handle all your document parsing requirements. Our aim is to simplify the complex process of document management, be it retrieval, parsing, or error handling. This includes effortless pagination, a plethora of supported document types, and meticulous error detail.

Versatility and Flexibility

Through our versatile APIs, you can not just retrieve uploaded documents but also queue documents for parsing either via a direct upload or through an external link. Our APIs are designed keeping in mind the dynamic nature of businesses and therefore, they seamlessly cater to varying business needs and configurations.

Swagger Configuration

The APIs are coded following the OpenAPI Specification (OAS), making the integration process hassle-free and straightforward. We provide complete Swagger UI-based documentation that details the potential responses and possible status and error codes.

Your Security, Our Priority

All API requests are authenticated via JWT headers for maximum security. This ensures that your sensitive document data remains protected at all times.

Let's Get Started

We are thrilled to have you onboard and can't wait to see how you integrate and maximize the utility of Import invoices in your document management operations!

Please make sure to replace "YourAuthTokenHere" with your actual bearer token.

}

In this code, we define a simple program with a single method `GetDocumentList`.

This method first sets up the authentication header by adding the bearer token to the HttpClient's default headers.

Then, it constructs the query parameters using a `System.Collections.Specialized.NameValueCollection` object.

It converts the query parameters to a `System.Net.Http.FormUrlEncodedContent` object and appends it to the request URL using a `System.Net.UriBuilder`.

If the request fails for any reason, an HttpRequestException will be thrown and the method will catch it and print the error message to the console.

If the request is successful, the method will read the response body as a string and print it to the console.

Query Parameters:

  • status (optional): Status filter conditions (0-2).
  • period (optional): Export filter conditions (0-16).
  • used (optional): Last used date (YYYY-MM-DD format).
  • confirmed (optional): Only filter confirmed documents (true/false).
  • page (optional): The page number for pagination.
Retrieve document details 
GET /v1/documents/{id}

A GET method that retrieves the details of a specific document from ParseDocuments.com using its primary key.

Example Request 
GET /v1/documents/1
Path Parameters
  • id: The primary key of the document.
Responses
  • 200 Success: Returns the details of the requested document.
  • 404 Not Found: The requested document is not found.
  • 400 Bad Request: The request was made incorrectly.

}

In this code, we define a simple program with a single method `GetDocumentDetails` that takes the document ID as an input parameter.

This method first sets up the authentication header by adding the bearer token to the HttpClient's default headers.

Then, it constructs the request URL by appending the document ID to the base URL.

If the request fails for any reason, an HttpRequestException will be thrown and the method will catch it and print the error message to the console.

If the request is successful, the method will read the response body as a string and print it to the console.

Path Parameters:

  • id: The primary key of the document.
Enqueue a document for parsing fields and tables using a base64 encoded binary representation 
POST /v1/documents/queue/base64

A POST method that enqueues a document for parsing fields and tables using a base64 encoded binary representation. The document is identified by its filename.

Example Request 
POST /v1/documents/queue/base64?filename=my_document.pdf
Query Parameters
  • filename (required): The identification of the file (filename).
Request Body 
{
    "type": "string",
    "format": "base64"
}
Responses
  • 201 Created: The document is successfully enqueued for parsing.
  • 404 Not Found: The requested document is not found.
  • 400 Bad Request: The request was made incorrectly.
