   In your chosen integration platform, start a new automation scenario, flow, or workflow. This is where you will visually design the sequence of actions.

5. Step 5: Configure the Initial Trigger

   Determine how your workflow will start. Common triggers include:

   • A webhook receiving data (e.g., from a form submission).
   • A new item in a database or spreadsheet.
   • A new email arriving in your inbox.
   • A scheduled event (e.g., running every hour).

   Add the appropriate module as the first step in your scenario.

6. Step 6: Add and Configure the Claude Module

   Search for and add an "Anthropic Claude" or "HTTP Request" module to your scenario, depending on your platform's direct integration capabilities. Configure the module:

   • Connection: Create a new connection using your Claude API key.
   • Method: Usually POST for sending prompts.
   • URL: Use the appropriate Claude API endpoint (e.g., for completions or messages).
   • Headers: Include necessary headers like x-api-key (with your Claude API key) and Content-Type: application/json.
   • Body: Construct the JSON payload containing your prompt, desired model (e.g., claude-3-opus-20240229), and other parameters. Map data from your trigger step into the prompt.

7. Step 7: Add and Configure the Gemini Module

   After the Claude module, add a "Google Gemini" or "HTTP Request" module for Gemini. Configure it:
