• Rate limits How many requests you can make, and what to do when we ask you to slow down.
• Idempotency Retry a write without creating a contact twice.
• Creating and changing contacts How a created contact is matched and synced, and what a change does.
• Errors Every error code the API returns.
• Triggers Poll for new contacts, changes, merges, duplicates and accounts that need attention.
• Webhooks Get an event posted to your URL when a contact is created, instead of polling.
