API Key

About Apollo.io API key

An Apollo.io API key grants programmatic access to Apollo's B2B database and engagement features, including contact and company search, email and phone enrichment, and CRM sync operations. API access is tiered by plan: basic API is available on the Professional plan ($79/user/month annual), while advanced API capabilities (custom reporting, international dialer, bulk operations) require the Organization plan ($119/user/month annual, 3-user minimum). API keys are created per-user in the Apollo dashboard and used to authenticate REST API calls.
