Schema, data formats and cache

This document provides foundational information that you might need to know if you want to call the Trustpilot API.

Schema

An API schema defines the types, constraints and structure of any data passed between a client and a server.

Trustpilot’s API schema supports the HTTPS protocol. Other protocols, such as RPC are not supported.

Data formats

The Trustpilot API supports JSON as the request and response format. The Cross-Origin Resource Sharing (CORS) policy is enabled for Get requests. All date/time responses are returned using ISO 8601 format using UTC.

Cache

Trustpilot caches some results on API servers. Cached results will include HTTP header information about client cacheability.
