# Chat with Vendor/Delivery Boy

Customer can now chat with delivery boy or vendor. 

To use the feature, you will need to make a small change/configuration to some files in the Customer flutter app.

You need to set your **firebase server key** to be able to allow message to be sent to vendor/delivery boy.

Go to **\[PROJECT\_FOLDER] > lib > constants > app\_strings.dart,** you will see a variable called **firebaseServerToken**.

Change the value for that variable to your the server key gotten from your firebase project.

static String **firebaseServerToken** = **"YOUR\_FIREBASE\_PROJECT\_SERVER\_KEY"**;
