Introduction

Bubble is a no-code platform that allows you to build web applications without writing code. This guide will show you how to integrate Helicone with your Bubble application to get observability and logging for your LLM API calls.

​
Integration Steps

1

Create a Helicone account and generate an API Key

Log into Helicone or create an account. Once you have an account, generate an API key.
Make sure to generate a write-only API key.
2

Configure API settings in Bubble

In your Bubble application, go to the API section and set up your LLM provider (e.g., OpenAI, Anthropic).See Figure 1 below for an example configuration.
3

Add Helicone headers

In the API settings, add the following headers:
  1. Add a private header for your Helicone API key:
    • Name: Helicone-Auth
    • Value: Bearer your_helicone_api_key
  2. Add a private header for your LLM provider’s API key:
    • For OpenAI:
      • Name: Authorization
      • Value: Bearer your_openai_api_key
    • For Anthropic:
      • Name: X-API-Key
      • Value: your_anthropic_api_key
Read about how to connect other LLM providers here.
Make sure to mark the API key headers as private to keep them secure.
See Figure 2 below for an example header configuration.
4

Update the API endpoint

Change the API endpoint to use Helicone’s proxy. For example, if you’re using OpenAI:
https://oai.helicone.ai/v1/chat/completions
Make sure to use the appropriate Helicone endpoint for your LLM provider.
5

(Optional) Add user tracking

To track requests by user, add another header:
  • Name: Helicone-User-Id
  • Value: "current_user's_email" (or any unique identifier)
You can make this dynamic by using Bubble’s expression editor to insert the current user’s email or ID.

​
Verifying the Integration

After setting up the integration:
  1. Make a test API call from your Bubble application.
  2. Go to your Helicone dashboard.
  3. Check the “Requests” section to see if your test call appears.
  4. You can view detailed information about each request, including cost and performance metrics.

​
Troubleshooting

  • If you don’t see requests in your Helicone dashboard, double-check that you’ve updated the API endpoint to use Helicone’s proxy.
  • Ensure that all required headers are correctly set and that API keys are valid.
  • If using user tracking, make sure the Helicone-User-Id header is properly formatted and not marked as private.
