Adding OAuth 2.0 as an authentication method in workflows(specifically, Custom Webhooks) would make it much easier to connect with other platforms, like Lightspeed for e-commerce. Right now, we're limited to basic auth, bearer tokens, and API keys, but many modern platforms only use OAuth 2.0. This means without it, we can't directly send data from GHL to many services, like Lightspeed to push real-time inventory, for example. OAuth 2.0 would make these connections simple, secure, and remove the need for middleware(either custom or Zapier).
