# List WhatsApp numbers

GET https://%7BYour_Space_Name%7D.signalwire.com/api/messaging/whatsapp/numbers

Lists the WhatsApp numbers connected to the project. These numbers act as WhatsApp senders and can route inbound communication to SignalWire resources. Prefix a number with `whatsapp:` when [sending messages](/docs/platform/messaging/whatsapp/send-messages). Standard SMS and MMS long codes use the [Phone Numbers API](/docs/apis/rest/phone-numbers/list-phone-numbers).

#### Permissions

The API token used to authenticate must have the following scope(s) enabled to make a successful request: _Numbers_.

[Learn more about API scopes](/docs/platform/your-signalwire-api-space).

Reference: https://signalwire.com/docs/apis/rest/whatsapp/list-whatsapp-numbers

## Authentication

- `Authorization` header (basic auth, required) — SignalWire Basic Authentication using Project ID and API Token. The client sends HTTP requests with the Authorization header containing the word Basic followed by a space and a base64-encoded string of project_id:token. The project ID will be used as the username and the API token as the password. Example: ``` Authorization: Basic base64(project_id:token) ```
