What you’ll need
You don't need to be a developer to set up this integration. Follow this simple guide to get started:
- A Relevance AI account
- An Airtable account with access to the base and table you'd like to use
- Authorization (you'll connect securely using OAuth—no sensitive info stored manually)
Security & Reliability
The Countdown API integration provides secure OAuth authentication, ensuring that only authorized workflows can access real-time eBay product data. Relevance AI manages API operations (like fetching product information, reviews, and search results) in the background—eliminating the need for manual rule maintenance or web scraping.
With built-in validation and structured data retrieval, your workflows can seamlessly access product details across 20+ eBay marketplaces, ensuring smooth operation even when data formats vary.
No training on your data
Your data remains private and is never utilized for model training purposes.
Security first
We never store anything we don’t need to. The inputs or outputs of your tools are never stored.

To get the most out of the Countdown API + Relevance AI integration without writing code:
- Start with a clear configuration: Ensure your OAuth credentials and API settings are correctly set up before making requests.
- Utilize structured data: Leverage the structured product data and reviews returned by the Countdown API for better insights and analysis.
- Connect carefully: Verify that you are using the correct eBay domain and EPID when making API calls to avoid errors.
- Test before scaling: Conduct tests with sample data to ensure your integration works as expected before deploying it on a larger scale.
- Implement error handling: Use try-catch blocks to manage API errors gracefully and log issues for troubleshooting.
- Monitor rate limits: Keep an eye on API response headers for rate limit information and implement throttling to avoid hitting limits.
