Completely new to .bubble here. Trying to build a two-sided marketplace where people can hire freelancers for services. Some of the services would be of a consultative nature (e.g. one hour advisory phone call where the buyer can ask the freelancer specific questions relating to their expertise). We’d like for the calls to happen within the platform, and for the process to be as pain-free as possible for the user. Wondering if anyone knows of any APIs for audio or video calls that play well with .bubble that may work for our purposes?
