FTP

FTP (File Transfer Protocol) is a standard network protocol used to transfer files between a client and a server over a TCP-based network. FTP is a protocol specification rather than a vendor or HTTP API, and is documented primarily in IETF standards (RFC 959 and follow-ups) and in widely deployed server implementations such as vsftpd, ProFTPD, Pure-FTPd, and FileZilla Server. This index links to the canonical specifications and documentation for the protocol; no OpenAPI is generated because FTP is not an HTTP API.

FTP is profiled on the APIs.io network. Tagged areas include FTP, File Transfer, Network Protocol, IETF, and Standard.

FTP’s developer surface includes documentation and 9 more developer resources.
