JWT OAuth 2.0 Bearer Token Flow || Salesforce Inbound

In this deep-dive session, I walk through a complete JWT OAuth 2.0 integration — where a Node.js backend securely authenticates to Salesforce using a signed JWT.

This is a real-world implementation, not just theory. You’ll see me:

  • Provide JWT Overview
  • Set up a Connected App in Salesforce
  • Generate private/public key pair
  • Sign the JWT using Node.js
  • Call Salesforce’s token endpoint
  • Handle access tokens and call APIs
  • Debug and troubleshoot live

If you’re building secure server-to-Salesforce integrations, this flow is critical. It’s passwordless, scalable, and ideal for headless automation.
