The goal is to enhance our social media management process by enabling simultaneous posting across multiple platforms, thereby improving efficiency and maintaining consistency in engagement. The API should support multiple clinics, allowing each clinic to post once through our system, which will then distribute the post to all their social media accounts.

Additionally, during onboarding, I plan to ask users to link their Facebook page, TikTok account, Instagram account, and YouTube account, with each being optional to link. How can I achieve this?
