Calling endpoint within another endpoint

Hi, I need to get the result of one of my endpoints, but I can't just call the underlying function directly — because every endpoint is wrapped with security and middleware before being exposed through the tRPC appRouter. So instead of bypassing those layers, I need to trigger the full chain — essentially making a proper call to the endpoint itself (as if it were external), even from inside another tRPC procedure. What's the recommended way to do this?

Can I call tRPC procedure inside another procedure? - Theo's Typesa...

Something like this:

export const mainRouter = createTRPCRouter({
 create: privateProcedure   
    .mutation(async ({ ctx }) => {
     ...
     doSomething({someInput: ""}) // call doSomething here with inputs
    }),
 doSomething: privateProcedure
    .input(
      z.object({
        someInput: z.string(),
      })
    )
}

export const mainRouter = createTRPCRouter({
 create: privateProcedure   
    .mutation(async ({ ctx }) => {
     ...
     doSomething({someInput: ""}) // call doSomething here with inputs
    }),
 doSomething: privateProcedure
    .input(
      z.object({
        someInput: z.string(),
      })
    )
}
