What method is used to associate a Social Studio account with Marketing Cloud?

The method to associate a Social Studio account with Marketing Cloud is to log into Social Studio from the Marketing Cloud tab. This process involves leveraging the seamless integration built between the two platforms, allowing users to manage social media marketing efforts directly within the Marketing Cloud interface. By using this method, marketers can access the functionalities of Social Studio easily without the need for complex configurations or additional steps.

The other options involve different contexts that do not specifically facilitate the direct association of the accounts. Submitting an integration request is typically a process for setting up connections between different systems but does not apply directly to the straightforward integration of Social Studio with Marketing Cloud. Utilizing API keys for integration pertains more to custom integrations and programming, which is not necessary for standard account linking. Accessing through Facebook settings refers to managing Facebook pages or ads but does not address the integration process needed to link Social Studio with Marketing Cloud.
