What it can do

Tool names and descriptions exactly as the server reported them on Nov 6, 2026. The maker wrote them, not us; we show them as plain text.

• api_key_check

  Returns the user the request acts for, the user's plan and the scopes of the API key or connected app that made it. Any live key or access token can call it, so call it to test one.

• contact_find

  Finds the user's contacts by email address, phone number or text. Give at most one of `email`, `phone` and `query`: - `email` finds the contacts with that address. Case does not matter. - `phone` finds the contacts with that number, however it is formatted. - `query` searches the

• contact_create

  Adds a contact. If the user already has this person, the values may go to that contact instead: - If the user's Auto-Merge level covers the match, the values are added to the existing contact: 200, `merged`. - Otherwise a new contact is created: 201, `created`. If it may be a dup

• contact_read

  Returns one contact. `id` is the contact's `id` or its `publicId`, such as `CS-0042`. A deleted or merged contact is a 404, and so is another user's contact.

• contact_change

  Changes a contact, as editing it in ContactZapp does. Only the fields you send change. A field you leave out keeps its value. The change goes to every two-way account the contact is in, never to a read-only one. History records it as the user's change and names the API key or the

• sync_start

  Starts a sync, the same as Sync now in ContactZapp. History shows it as a manual run. The answer is 202 with the sync's state, `queued` or `running`. If a sync is already going, you get that one back and no second one starts.

• event_list

  Lists the events of one type, newest first. Zapier, Make and n8n poll this to start an automation. Each item's `id` never changes. Poll again and the items you already have come back with the same ids, with new ones on top. Skip the ids you have seen. - `contact.created`, `contac
