Hi,

We've recently started exploring the migration from Auth0 to FusionAuth, and I was wondering if there's a way to read the body of a request using a Lambda. In Auth0, the equivalent would be an Action with the onExecuteCredentialsExchange, which includes the event parameter that allows us to access the request body.

I noticed that the client credentials Lambda structure in FusionAuth has four arguments: jwt, recipientEntity, targetEntities, and permissions. However, we need to augment the JWT claims with a value passed in the body of the client credentials grant request.

Is there a way to achieve this?

Thanks!
