When making requests to the SalesLayer REST API, specific headers are required to authenticate and customize the response.
Below is a description of the headers used across all endpoints and their purpose.
X-API-KEY
- This header is mandatory for all API requests and must include your unique API key to authenticate the request.
X-API-KEY: your-api-key-here
Accept-Language
- This header specifies the language in which the API should return the response.
- If omitted, the API will default to the language configured for your account in SalesLayer.
- When your catalog items have multilanguage fields (including local languages), you can use this header to specify the desired language for those fields.
Accept-Language: en-us
