Interface
The types of data are:
HTTP Methods
HTTP Client Header
URI
Body
HTTP methods, URIs, and HTTP versions are called request lines.
The maximum allowable request line length is 1,280 bytes.
If you send a request whose line length exceeds the upper limit, the API fails with HTTP status code 413.
Note
The character set used for RESTful API is UTF-8. For more information about the possible characters, see RFC3986.
In the command reference, the upper limit of each query parameter is listed. However, when the total line length of the request exceeds 1,280 bytes, the API fails even if the number of values for the query parameter does not reach the upper limit.
