Methods and systems for integrating computer applications

A computer-implemented method for associating a first object maintained by a first computer application with a second object maintained by a second computer application, the first and second computer applications being independent computer applications, the computer-implemented method comprising:

• installing an auxiliary module provided by the first computer application in a second client associated with the second computer application;
• displaying, by the auxiliary module, an interactive element in a user interface generated by the second client, the user interface displaying the second object, the interactive element including a control to associate the second object with the first object;
• in response to detecting a selection of the control, generating by the auxiliary module, an association request, the association request including a first identifier of the first object and a second identifier of the second object;
• communicating, by the auxiliary module, the association request to the first computer application to cause the first computer application to create a correspondence record in a correspondence table, the correspondence record associating the first object with the second object and including the first and second identifiers;
• receiving, by the auxiliary module, object data associated with the first object from the first computer application;
• and
• displaying the object data associated with the first object in the interactive element.
