Terminal device, server, and method of providing messaging service

A server comprising:

• a communication circuitry;
• and
• a processor configured to:
• control the communication circuitry to receive a request for invitation information with respect to a messaging group corresponding to a first messaging service from a first electronic device that is external to the server,
• in response to receiving the request, generate the invitation information including a link to the messaging group, and
• when the invitation information including the link is generated, control the communication circuitry to transmit the invitation information including the link to the first electronic device such that at least part of the invitation information including the link is to be transmitted from the first electronic device to a second electronic device external to the server via a second messaging service established between the first electronic device and the second electronic device.

A non-transitory machine-readable storage device storing instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:

• presenting, at an electronic device, a user interface corresponding to a first messaging service;
• transmitting, to a server, a request for invitation information with respect to a messaging group corresponding to the first messaging service based at least in part on a user input received via the user interface;
• in response to transmitting the request, receiving the invitation information from the server;
• and
• when the invitation information is received from the server, transmitting at least part of the invitation information to an external electronic device via a second messaging service, the external electronic device being external to the non-transitory machine-readable storage device.
