Hi, you can do it in this way

```auto
resources:
....
  Outputs:
    UserPoolId:
      Value:
        Ref: CognitoUserPool
      Export:
        Name: ${self:provider.stage}-UserPoolId

    UserPoolClientId:
      Value:
        Ref: CognitoUserPoolClient
      Export:
        Name: ${self:provider.stage}-UserPoolClientId

```

```auto
functions:
   your-function:
     ....
     environment:
       USER_POOL_ID: !ImportValue ${self:provider.stage}-UserPoolId
       USER_POOL_CLIENT_ID: !ImportValue ${self:provider.stage}-UserPoolClientId

```

your-function.js

```auto
   const { USER_POOL_ID, USER_POOL_CLIENT_ID } = process.env;
   ...

```

p.s.  
If your functions + resources are in the same stack - you can just use `USER_POOL_ID: !Ref CognitoUserPool` and `USER_POOL_CLIENT_ID: !Ref CognitoUserPoolClient`
