ETC header
The POPBiLL API allows you to set additional headers to specify the language of the response message and the encoding method.
Accept-Encoding
When the client sets an Accept-Encoding value in the request header, the POPBiLL API returns an encoded response. An encoded response reduces network transfer size and helps improve response speed when retrieving large amounts of data.
Accept-Encoding: gzipIf the client does not send the Accept-Encoding header, the server generally returns a response without compression. To receive a compressed response such as gzip, the client must support the requested compression method and be able to correctly decompress the response body.
Accept-Language
Response messages from the POPBiLL API are provided in Korean by default. If an English response is required, you can set the Accept-Language value in the API request header to specify the response message language as English.
Accept-Language: en-US
