## Connect Zoho CRM

:::steps
1. **Open the catalogue.** In the console, go to **Data · Connections** and press **New connection**.
2. **Choose Zoho CRM.** It is listed under crm and support; you can also search for it by name.
3. **Fill in the form.** Enter the fields below. Credentials go straight to sanda’s sync engine and are never stored in sanda’s database.
4. **Choose what to sync.** Pick the tables you want, and a sync mode for each. See [choose what to sync](https://docs.sanda-os.com.au/connections/choose-tables).
5. **Run the first sync.** sanda tests the connection, then lands each table you chose in your warehouse.

## Configuration fields

What the connection form asks for. Required fields are marked; the rest are optional.

| Field | Type | Required | Description |
| --- | --- | --- | --- |
| **Max Concurrent Requests** | integer | No | Maximum number of concurrent requests to the Zoho CRM API. When left empty, the connector detects your Zoho CRM edition via the organization API and uses that edition's limit (Free: 5, Standard: 10, Professional: 15, Enterprise: 20, Ultimate: 25), defaulting to 5 if detection fails. Set this to raise the limit without re-authenticating, or to throttle the connector when sharing API credits with other integrations. |
| **Client ID** | string, secret | Yes | OAuth2.0 Client ID. |
| **Client Secret** | string, secret | Yes | OAuth2.0 Client Secret. |
| **Data Center Location** | string | Yes | Please choose the region of your Data Center location. One of `US`, `AU`, `EU`, `IN`, `CN`, `JP`. |
| **Environment** | string | Yes | Please choose the environment. One of `Production`, `Developer`, `Sandbox`. |
| **Refresh Token** | string, secret | Yes | OAuth2.0 Refresh Token. |
| **Start Date** | string | No | ISO 8601, for instance: `YYYY-MM-DD`, `YYYY-MM-DD HH:MM:SS+HH:MM` |
