Send SMS

Use this endpoint to send messages to your recipients, either as phone numbers or contacts from your contact list.

You can send messages both locally and globally, subject to the country restrictions. The cost of sending messages varies based on the type and length of the message.

Request
header Parameters
Content-Type
string
Example: application/json
Request Body schema: application/json
Array of objects (senders)

The senders property specifies sender IDs for each recipient country.

  • Want to leverage the default sender settings:

    • If the senders property is missing or left empty, the system uses the default sender settings configured for each recipient country.

  • Want to override the default sender settings:

    • When the senders property is provided, it should contain valid sender IDs for each recipient country listed under recipients. These IDs will override the default sender settings for the specified countries.
    • If an invalid sender ID is provided, or a sender ID for a specific recipient country is missing, the system will revert to using the default sender settings for that country.
The senders parameter is currently in beta and available only to beta testing users.
