POST /v1/email-marketing/contacts/{contact_id}/messages
Send one SMS to one contact, paid from the Zinn® credit balance.
Authentication
Send an API key as a bearer token. The key must carry the email_marketing.manage permission; a key without it is refused with 403, not 404.
Where your organisation id goes
This endpoint takes org_id as a query parameter. Leave it out and the call covers your whole tenancy subtree; send it to narrow the call to one organisation.
Your organisation id is on the API keys screen in your dashboard, beside the key itself. It is the same id in every call you make.
Try it
Replace anything in angle brackets with your own values, and the key placeholder with a key from your dashboard.

Details
Gated on email_marketing.manage. Every guard runs before the provider is called: the line and SMS switches, the account's good standing, the contact's SMS consent, this organisation's spike pause, an open country, and the credit — the price (parts x the country's price per part) is debited BEFORE sending and returned if the network refuses the message. Refusals carry a refusal.campaigns.channel* key: CAMPAIGNS_NO_CREDIT (402), CAMPAIGNS_NO_CONSENT / CAMPAIGNS_SUPPRESSED / CAMPAIGNS_NO_PHONE / CAMPAIGNS_PAUSED (409), CAMPAIGNS_UNPRICED / CAMPAIGNS_COUNTRY_NOT_OPEN / CAMPAIGNS_VENDOR_REFUSED (422), CAMPAIGNS_TOO_LONG (400), CAMPAIGNS_NOT_OPEN / CAMPAIGNS_CHANNEL_OFF / CAMPAIGNS_ACCOUNT_ON_HOLD (403), and CAMPAIGNS_VENDOR_UNAVAILABLE / CAMPAIGNS_NOT_CONFIGURED (503). One message per call; audited (email_marketing.message.send).
