## Setting up Intercom for ELT & CDC

### Overview

ELT & CDC uses the API provided by Intercom to sync the data. [Intercom API Reference](https://developers.intercom.com/docs/references/rest-api)

### Requirements

* You need to authenticate via OAuth2.
* Click the Authenticate button on the dashboard, sign in to Intercom, and grant access to Integrate.io.

### Sync modes

Streams that expose a server-side `updated_at` filter through the Intercom Search API run in Continuous Sync: `Contacts`, `Conversations`, `Tickets`, and `Conversation Parts` (which rides the incremental `Conversations` stream). `Companies` uses the Intercom Scroll API and the reference collections (`Admins`, `Teams`, `Tags`, `Segments`, `Data Attributes`, `Articles`) run as full-refresh on each sync because their list endpoints do not expose an `updated_at` filter.

### Notes

* `Data Attributes` uses a composite primary key of `(model, full_name)` because standard Intercom attributes have a null `id`.
