Method	`POST`
Operation	`post_notify_send_sms`
Auth	`Authorization: Bearer $HANZO_API_KEY`

Delivers one transactional SMS through the caller org's own provider credential.

It is the channel-pinned form of the generic send: identical in every respect except that the channel is fixed to sms, OVERRIDING whatever the body names — so a body that says email still goes out as a text message. The provider is the org's own SMS credential from KMS (Twilio, then Plivo), resolved for the validated principal's org; an unauthenticated caller gets 401.

Request

9 fields, body application/json (required).

Field	In	Type	Required	Description
`body`	body	string	—	Body is the message text, sent verbatim when present — the no-template path.
`channel`	body	string	—	Channel selects the delivery channel, sms or email.
`event`	body	string	—	Event is the event name, which doubles as the template id when TemplateID is empty — the IAM OTP path sends event=iam.otp_sent and nothing else.
`provider`	body	string	—	Provider pins a provider service name (twilio, plivo, twilio_email, mail).
`subject`	body	string	—	Subject is the message subject, carried on the email channel only.
`sync`	body	string	—	Sync must be exactly "true": delivery here is synchronous, and anything else answers 503 because the queue plane that would run an async dispatch is owned elsewhere.
`template_id`	body	string	—	TemplateID selects a built-in template when Body is empty.
`template_vars`	body	any	—	TemplateVars carries the values the selected template renders against, as a raw JSON object.
`to`	body	string[]	—	To is the destination address per recipient — a phone number for sms, an email address for email.

Response

Status	Body	Meaning
`200`		ok
`default`	problem-details	refused

200 body — 1 field.

Field	In	Type	Always	Description
`(body)`	body	any	yes

MCP reaches notify through the notify tool, which names its 4 operations with its own verbs — this one among them, under a name only MCP declares. describe explains any of them:

curl -X POST https://api.hanzo.ai/v1/mcp \
  -H "Content-Type: application/json" \
  -d '{
       "jsonrpc": "2.0",
       "id": 1,
       "method": "tools/call",
       "params": {
         "name": "describe",
         "arguments": {
           "op": "get_notify_health"
         }
       }
     }'
