Hello Nikki,

Using the DigitalOcean App Platform to trigger Functions and retrieve the results involves a few steps, including setting up your Functions, triggering them from your application, and handling the response. Here’s a general guide to help you get started:

  1. Setting Up Your Functions in DigitalOcean:

    • First, you need to create and deploy your Functions in the DigitalOcean App Platform.
    • Write your function code in your preferred language (e.g., Python, JavaScript) and define the actions it should perform.
    • Deploy these Functions to the DigitalOcean App Platform. This process typically involves creating a new app in the App Platform and uploading your function code.
  2. Triggering Functions from Your Application:

    • Once your Functions are deployed, you can trigger them using HTTP requests. This can be done from any part of your application that can make HTTP calls.
    • For example, if you’re using Python, you can use the requests library to send a request to the Function’s endpoint:
      import requests
      url = ''
      response =, data={'key': 'value'})
    • Replace with the actual URL of your deployed function. The method (GET, POST, etc.) and data format depend on how your Function is set up to receive requests.
  3. Retrieving and Handling the Results:

    • After triggering the Function, you’ll receive a response. You need to handle this response in your application.
    • Continuing with the Python example:
      if response.status_code == 200:
          result = response.json()  # or response.text if the response is not JSON
          print("Function result:", result)
          print("Error calling function:", response.status_code)
  4. Error Handling:

    • Always include error handling when making HTTP requests. This ensures your application can gracefully handle situations where the Function is unavailable, or an unexpected response is received.

As always, make sure to test your function calls extensively to ensure they work as expected. Debug any issues that arise, paying close attention to the response data and HTTP status codes.

Hope that this helps!
