difference between oauth/v2/authorize & openid/connect/authorize
I am taking the example in context of Slack .
1. OAuth 2.0 (/oauth/v2/authorize):
Usage: When a third-party application needs to access a user's resources in Slack, it uses the /oauth/v2/authorize endpoint.
Process: The user is prompted to grant the application permission to access their resources. Upon consent, Slack returns an authorization code to the application. This code is then exchanged for an access token, which the application uses to access the user's resources on Slack.
Focus: Purely on granting access to resources (authorization).
2. OpenID Connect (/openid/connect/authorize):
Usage: When an application not only needs to access resources but also verify the identity of the Slack user, it uses the /openid/connect/authorize endpoint.
Process: Similar to OAuth 2.0, but in addition to granting access, this process authenticates the user and returns an ID token along with an authorization code. The ID token contains claims about the user's identity, which can be used by the application to verify who the user is.
Focus: On both verifying user identity (authentication) and granting access to resources (authorization).

export TF_LOG=DEBUG this sets the TF_LOG environment variable to DEBUG, instructing Terraform to output detailed debug logs during its execution( Terraform apply ).
unset TF_LOG this unsets (removes) the TF_LOG environment variable, effectively turning off debug logging for Terraform execution.

Related to Auth0 and react-auth0 sdk
To add a custom parameter to the authentication endpoint of which auth0 interacts we can pass it like this in the object

Code

authorizationParams: {
          screen_hint: "signup",
          ui_locales: "en",
          custom_param: "custom_param",
        },


authorizationParams object is used in methods loginWithRedirect, withAuthenticationRequired provided by @auth0/auth0-react

once the custom parameter is passed we can see it in /authorize endpoint when we open the Universal login or signup form from Auth0

If we want to take any custom actions based on this custom parameter we can access it in Auth0 post login custom actions

Your competitors are already using AI.
The question is how fast you want to unlock the value.

Don't know where to start?

AI is everywhere but it's unclear which investments will actually move your metrics and which are expensive experiments.

Your data isn't ready

Most AI projects fail at the data layer. Pipelines, quality, access all need work before LLMs can deliver value.

Internal teams are stretched

Your engineers are shipping product. They don't have capacity to also become AI specialists with production-grade experience.

Legacy systems block everything

Aging, undocumented codebases make AI integration slow, risky, and expensive. They need to move first.

Don't worry. We've got you covered.

Start with the audit.
