I developed an API using FastAPI that accepts a Word document upload and extracts its contents, deploying it on Heroku. Below is the complete code for the API along with a client for testing it. The testing client successfully retrieves the desired output.

API Code:

import os
import uvicorn
from fastapi import FastAPI, UploadFile, File
import docx
from io import BytesIO

app = FastAPI()

@app.post("/extractdoc")
async def extractdoc(uploaded_file: UploadFile = File(...)):
    document = docx.Document(BytesIO(await uploaded_file.read()))
    text_content = []
    for paragraph in document.paragraphs:
        text_content.append(paragraph.text)
    return '\n'.join(text_content)

if __name__ == "__main__":
    uvicorn.run(app, host="0.0.0.0", port=int(os.environ.get("PORT", 8080)))

Test Client Code:

import requests

word_file = "path_to_your_word_file.docx"
files = {'uploaded_file': (word_file, open(word_file, 'rb'))}

res = requests.post('https://extractdoc.herokuapp.com/extractdoc', files=files)

print(res.json())

Now, I want to integrate this API with RapidAPI. However, I’m having difficulty linking the /extractdoc endpoint for file uploads, as the only options I see involve requests for JSON or data. Is there a way to incorporate file uploads in RapidAPI?

To integrate your FastAPI with RapidAPI to handle file uploads, you'll need to set up the endpoint for multipart/form-data. Here's a quick guide:

  1. Define the Endpoint:
    • Go to your RapidAPI Provider Dashboard.
    • Create an API and point the URL to /extractdoc.
    • Specify that it accepts POST requests.
  2. Set Up Parameters:
    • In the endpoint, add a parameter for file uploads.
    • Set the parameter type to Form Data.
    • Use the name uploaded_file to match your FastAPI input.
  3. Testing:
    • Use RapidAPI’s testing tools to ensure the setup works.

This configures your API to handle file uploads via RapidAPI using multipart/form-data.

To expose your API with file upload capabilities on RapidAPI, you can configure it to handle multipart form-data, which is essential for file uploads. Here’s how to achieve this:

  1. Set Up Your Endpoint in RapidAPI Dashboard:

    • Navigate to the RapidAPI Provider Dashboard.
    • Create a new API, and set up your endpoint URL to point to your existing FastAPI service, e.g., /extractdoc.
    • During the endpoint setup, explicitly specify that it will receive a POST request.

  2. Define the File Upload Parameter:

    • In the endpoint settings, under ‘Requests,’ add a new parameter for file uploads.
    • Choose ‘Form Data’ as the parameter type, as file uploads require the multipart/form-data content type.
    • Name this parameter the same as in your FastAPI method, uploaded_file, and ensure it matches precisely with your API’s expected input.

  3. Configure Testing and Additional Parameters:

    • RapidAPI allows you to include descriptions and testing fields for your parameters, so it’s a good idea to fill these out to guide users on how to use your API.
    • Test your API through the RapidAPI platform to ensure the file upload is correctly processed by your FastAPI application.

Example of Endpoint Configuration:

  • Endpoint: /extractdoc
  • Request Type: POST
  • Content Type: multipart/form-data
  • Parameter:
    • Name: uploaded_file
    • Type: File (or form data)
    • Required: Yes

By doing this, you enable your API to accept file uploads through RapidAPI’s platform, utilizing the correct multipart data encoding. Lastly, ensure that the server hosting your API is robust enough to handle these file operations securely and efficiently.

This setup should help you integrate your existing API with RapidAPI, enabling file uploads efficiently.

To expose your FastAPI on RapidAPI with file upload support, ensure it handles multipart/form-data. Here's how you can set this up efficiently:

  1. Configure Your RapidAPI Endpoint:
    • Log in to the RapidAPI Provider Dashboard.
    • Create a new API and configure the endpoint URL to /extractdoc.
    • Set it to accept POST requests.
  2. Define Parameters for File Upload:
    • In the endpoint settings, add a parameter for file uploads.
    • Select 'Form Data' as the type, required for multipart/form-data uploads.
    • Name the parameter uploaded_file to match your FastAPI function.
  3. Test the Endpoint:
    • Test using RapidAPI’s tools to verify the configuration.

This setup allows file uploads with multipart/form-data through RapidAPI, leveraging your existing FastAPI's file processing capabilities efficiently.
