Digital messages overview
#

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

SMS
#

Use the Voiso Outbound SMS API to enable external applications to send SMS. For example, you can use it to enable agents to send an SMS from your CRM.

Limitation: The SMS API does not currently allow you to send bulk SMS.

Send an SMS
#

The SMS API enables agents to send SMS to contacts from your web application or CRM using a POST request. Request and response payloads are formatted as JSON, using UTF-8 encoding and URL-encoded values.

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.

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

Voiso provides two methods to send a message to one or more contacts: Post messages and Get messages. Both methods have the same request and response structure.

Tip: Voiso recommends using the POST method for most applications.
