# WhatsApp Specific Variables

As part of FlowBridge Connect functionality, we will populate your flow with specific variable that you can use at your own will. All you need to do is create the variable name in Voiceflow and FlowBridge Connect will automatically populate them with information

Here are the WhatsApp specific variables you can create:

| Variable Name     | Value   | Description                                                                                                                                                                          |

| user\_name        | String  | The name of the user messaging you                                                                                                                                                   |
| phone\_number     | Integer | The phone number of the user, without the "+" added before it.                                                                                                                       |
| Channel           | String  | the channel the user is communicating on. It will be "whatsapp" for WhatsApp conversations                                                                                           |
| user\_id          | Integer | This is the same as phone\_number but exists to unify the variable naming across channels                                                                                            |
| channel\_user\_id | Integer | This is the same as phone\_number but exists to unify the variable naming across channels                                                                                            |
| phone\_number\_id | Integer | This is the Phone Number ID for the WhatsApp user. This can be used to send additional messages outside of the FlowBridge Connect platform and differs from the phone\_number itself |
