Saving files from third-party systems directly to a cloud storage system

A system for saving a file stored on a third-party system directly to a cloud storage system, the system comprising:

• a computer processor;
• and
• a memory storing a plurality of processor-executable instructions, the processor-executable instructions being executed by the computer processor to:
• communicate with a plurality of client computers using a communication connection;
• provide a plurality of third-party systems with an embeddable user interface for saving a plurality of files stored on the plurality of third-party systems to the cloud storage server hosting the cloud storage system;
• receive at the cloud storage server a first save request from a user on a first client computer in the plurality of client computers using the embeddable user interface on a first third-party system in the plurality of the third-party systems to select a first file in the plurality of files to be stored on the cloud storage server, wherein the first save request comprises:
• information identifying the first file in the plurality of files, and
• information identifying the user including an authorization token associating the user with the third-party system, wherein the authorization token is granted by the user via the embeddable user interface and allows the third-party system to directly access the user's account on the cloud storage system without use of the client computer as intermediary service;
• authenticate the first save request;
• download the first file from the first third-party system directly to the cloud storage server using the information identifying the file without passing the first file to the client computer;
• limit a speed that the files are downloaded from the first third-party system by the user when the amount of data exceeds a threshold;
• save the first file on the cloud storage server;
• store a master copy of a second file in the plurality of files sent from a second third-party system in the plurality of third-party systems, wherein the master copy is associated with a document ID;
• receive at the server a second save request from the user on the first client computer using the embeddable user interface on the second third-party system to select the second file to be stored on the server, wherein the second save request comprises the document ID;
• authenticating the second save request;
• creating a copy of the master copy on the server;
• and
• associating the copy of the master copy with the user.
