Salesforce Explorer

 I have done account sync between Salesforce (Source) to salesforce (Destination) using Lightning flow. Just visit Blog:  https://www.catchontosalesforce.com/p/http-post-via-lightning-flow.html

  We can authorize server to access data without  interactively logging  in each time and unable to share your client secrete. Just visit Blog:   https://www.catchontosalesforce.com/p/oauth-20-jwt-bearer-flow-for-server-to.html

I have created a sample javascript app with functionality of Authorization Code and Credentials Flow for Private Clients.  Just visit Blogshot:   https://www.catchontosalesforce.com/p /authorization-code-and-credentials-flow.html   Github : https://github.com/Priyananth-Salesforce/Headless-SF-Authenication--Login-Via-Javascript-App
