GatewayAPI bulk SMS setup for Ultra SMS

Steps

1. Sign in to the GatewayAPI Dashboard.
2. Create or copy an API key token.
3. Note which platform your account lives on: gatewayapi.com or gatewayapi.eu.
4. In Ultra SMS open the Gateways tab, click Add gateway, choose GatewayAPI, and paste the token and pick the platform. Click Test credentials (it sends nothing).
5. Send a test message to your own phone before you start a campaign.

Good to know

• GatewayAPI's statuses only arrive by webhook, which Ultra SMS does not receive.
• This gateway has no delivery look-up in Ultra SMS, so its messages show as Sent, not Delivered. Check the gateway's own dashboard or reports for final delivery.

Before you send through GatewayAPI

GatewayAPI charges per message segment at its own rates, which depend on the destination country. Check that your sender is allowed in each country you text. Business traffic to the USA normally needs A2P 10DLC registration or a verified toll-free number, and India needs DLT registration. Use Test credentials first, then send one real test to your own phone.

Dashboards change their menus from time to time; if a label differs, look for the API keys or developer section. Stuck? See the Ultra SMS troubleshooting table, the Ultra SMS user guide, or contact us.
