webhook_failover_urlstring url

The failover URL where webhooks related to this message will be sent if sending to the primary URL fails.

use_profile_webhooksboolean

If the profile this number is associated with has webhooks, use them for delivery notifications. If webhooks are also specified on the message itself, they will be attempted first, then those on the profile.

type'SMS' | 'MMS'

The protocol for sending the message, either SMS or MMS.

auto_detectboolean

Automatically detect if an SMS message is unusually long and exceeds a recommended limit of message parts.

encoding'auto' | 'gsm7' | 'ucs2'

Encoding to use for the message. auto (default) uses smart encoding to automatically select the most efficient encoding. gsm7 forces GSM-7 encoding (returns 400 if message contains characters that cannot be encoded). ucs2 forces UCS-2 encoding and disables smart encoding. When set, this overrides the messaging profile's smart_encoding setting.
