The Gelato API is organized around REST. Our API has predictable, resource-oriented URLs, and uses HTTP response codes to indicate API errors. We use built-in HTTP features, like HTTP authentication and HTTP verbs, which are understood by off-the-shelf HTTP clients. JSON is returned by all API responses, including errors.

Before you can use the Gelato API you will need to generate an API key via our API Portal. Read more here.
You authenticate your account by including your secret key in all API requests. Your API key carries privileges to create and manage your orders, so be sure to keep them secure! Do not share your secret API keys in publicly accessible areas such as GitHub, client-side code, and so forth.
To use your API key, you need to provide it in an
X-API-KEY header with each call.
All API requests must be made over HTTPS. Calls made over plain HTTP will fail. API requests without a valid API key will also fail.
The Gelato API uses conventional HTTP response codes to indicate the success or failure of an API request. In general: Codes in the 2xx range indicate success. Codes in the 4xx range indicate an structural or data error in the request (e.g., a required parameter was omitted, shipment prices are not found, etc.). Codes in the 5xx range indicate an error with Gelato's API servers (these are rare).
Error Code Meaning 200 OK -- Everything worked as expected. 400 Bad Request -- The request was unacceptable, often due to missing a required parameter. 401 Unauthorized -- No valid API key provided. 404 Not Found -- The requested resource doesn't exist. 429 Too Many Requests -- Too many requests hit the API too quickly. We recommend an exponential backoff of your requests. 500 Internal Server Error -- We had a problem with our server. Try again later. 502, 503, 504 Server Errors -- Something went wrong on Gelato's API end. (These are rare.).
