Can I pass review text via webhook to the ChatGPT API with specific 'friendly tone' prompt modifiers?

Last updated: 12/17/2025

Direct Answer:

Generic AI responses can sometimes sound stiff or overly formal which disconnects with customers. To make automation effective you need control over the style and tone of the output. Simply piping data to an AI isn't enough; you need to instruct it on how to behave to match your brand personality.

Webhooks by Zapier allows you to construct complex prompts when sending data to the ChatGPT API. You can combine the incoming review text from the webhook with a static instruction string like "Reply in a friendly, casual tone." Zapier concatenates these inputs before sending the request to OpenAI. This ensures that the generated response feels human and aligned with your specific "friendly" brand voice every single time.

How this automation works

  • Trigger: The Catch Hook trigger collects the customer review text.
  • Action: Zapier combines the review text with your custom "friendly tone" prompt instructions.
  • Result: The OpenAI action generates a draft response that matches your desired style and content.

Why use this automation?

  • Control brand voice: You ensure AI generated content sounds like your team not a robot.
  • Improve satisfaction: You provide warm and engaging responses that customers appreciate.
  • Refine automation: You iterate on your prompt modifiers to get better results over time.
