I am currently working on exposing the SF data as an API so the external system can consume it. I created a account for the external system to access the data through the API. Salesforce provides the external system gets the Access/Bearer Token through OAuth to access the data from the instance. I am trying to understand how long the Access/Bearer token is valid. I tried looking in to the Session setting in my instance and found that Session time out is like below
Does this mean the Access/Bearer token is valid for 4 hours? Please help me understand this.
