Draft funding-based cold email openers with Datahyena and OpenAI GPT-4o

Description

Quick overview
This workflow runs daily at 9am to fetch recent $1M+ funding events from Datahyena, uses OpenAI Chat Completions to generate a two-sentence cold email opener referencing each raise, and outputs a structured draft record with company and funding details.

How it works
Runs every morning at 9am on a schedule.
Requests up to 15 funding events from the last day from the Datahyena Funding Events API, filtered to rounds with at least $1M raised.
Splits the API response so each funding event is processed individually.
Sends the company and funding details to the OpenAI Chat Completions API to generate a concise, funding-aware cold email opener.
Outputs a cleaned draft object containing the company name, domain, round, amount, announcement date, and generated opener text.

Setup
Add an HTTP Header Auth credential for Datahyena (header X-API-Key) and select it in the Datahyena request step.
Add an HTTP Header Auth credential for OpenAI (header Authorization: Bearer ) and select it in the OpenAI request step.
Update the prompt text in the OpenAI request to replace “EDIT THIS WITH WHAT YOU SELL” with your actual offer.
Optionally connect a destination after the final output to store or send drafts (for example Google Sheets, Gmail, or a CRM).
