This article lists every Zoho CRM API endpoint the integration calls, grouped by data type. Use it to confirm which endpoints the integration depends on — for firewall allow-listing, OAuth scope configuration, troubleshooting, and checking whether a Zoho CRM API change affects the integration.

Sign in to Zoho CRM at https://accounts.zoho.com/signin?servicename=ZohoCRM. Subscribers in another data-center region sign in at the matching regional accounts host — see Base URL below.

The integration uses the Zoho CRM REST API, version v2. All endpoint paths below are shown with a [Base URL] prefix; the actual base URL is the Zoho API domain for your organization's data-center region, with /crm appended.

The region is chosen with the Region subscription setting. The US example is https://www.zohoapis.com/crm; other regions use the matching www.zohoapis.<region> domain, which Zoho returns to the integration when the connection is authorized. The OAuth accounts host used to obtain tokens is region-specific in the same way:

A single production Zoho CRM organization is used per subscription; the integration does not call a separate sandbox host.

Retrieves products a page at a time.

Used when matching an order line's SKU to a Zoho CRM product.

Customers are held in the Zoho CRM Contacts module.

Reads contacts a page at a time during a scheduled poll.

The integration reads a module's field definitions to match mapped custom fields to Zoho CRM fields, and can create custom fields in a module.

{Module} is Contacts, Products, or Sales_Orders.

Exchanges the authorization code for an access token and refresh token, and later refreshes the access token. The host is the region-specific accounts host shown in the Base URL table above (for example https://accounts.zoho.com/oauth/v2/token for the US region).
