Sugar REST API
The Sugar REST API is hosted on each Sugar deployment at https:///rest/v{version}/ (v10 through v11.27). SugarCloud instances are hosted on Sugar's own sugarondemand.com domain, so a cloud tenant's base is https://{instance}.sugarondemand.com/rest/v11_27/; on-site deployments substitute the customer's own site URL. It authenticates with two-legged OAuth 2.0 (password + refresh_token grants, OAuth-Token header), returns JSON with ISO 8601 dates, uses offset pagination, and exposes CRM modules through /{module} and /{module}/filter routes. Each instance serves its own endpoint reference at /rest/v{version}/help; no public OpenAPI is published.
