Connection
- Authentication: API key.
Apollo → Settings → Integrations → API Keys → Create new key. Name it, then tick only the endpoints matching what you grant this agent (contacts, accounts, deals, tasks, sequences, users…) — least privilege, and it is enough for most actions here. Depending on your Apollo plan, some endpoints may require the key to be a “master key” instead (Apollo’s docs single out the plain users-list endpoint); if a call fails with a 403, that specific endpoint likely needs it — a master key grants access to every endpoint on your Apollo account, so treat it like a password. Click Create API key, then copy the key.See Apollo.io’s documentation.
