# Overview

Use the Voiso Digital Messages APIs to initiate digital interactions from third-party applications, such as CRMs.

## WhatsApp

Use the Voiso WhatsApp outbound messaging API to send messages to contacts.

### Send WhatsApp to one or more recipients

Add WhatsApp messaging capabilities to your application.

For example, you can use WhatsApp messaging for the following use cases:

- As part of an automation flow using a third-party tool.
- Marketing campaigns that target multiple WhatsApp users.
- Transactional traffic that sends confirmations to contacts, for example, to confirm an account update.

          Important

          

WhatsApp only supports pre-approved message templates when sending messages to WhatsApp users. Contact your Voiso representative about creating WhatsApp message templates.

Voiso provides the [Send messages](/v1-api/apidocs/send-messages) method for sending messages to one or more contacts.

          Limitations

          

- There is a throttling limit of 50 API calls per second.
- There is a maximum of 100 recipients per API call per second. Additional recipients are rejected.
