Interaction of GPTs with field services

Is it possible for a GPT agent to communicate with external services? specifically in terms of exports. For example, connect to Teshegram or WhatsApp ? so that you can communicate with the GPTs agent. Tell me how this can be done, is it possible to use the API of specific GPTs agents?

Welcome to the forum.

Custom GPTs are only available in the ChatGPT ecosystem. You can replicate some of the functionality on your own with Assistants API, but it’s not exactly the same.
