What happens if a company is not found in the database?
If a company is not found, Harmonic will return a 201 Enrichment Triggered status. This means a background update has been queued. You can check the status later using the get_enrichment_status tool.
Can I search for companies based on specific criteria?
Yes! Use the search_startups tool. You can provide a JSON string with filters like headcount, location, or industry to find companies that match your investment or sales criteria.
Is the integration secure?
Absolutely. The integration only accesses your data through your unique API key. Your credentials are encrypted and stored securely within the Vinkius Cloud infrastructure.
