Kaleyra bulk SMS setup for Ultra SMS
An enterprise CPaaS (now part of Tata Communications) for SMS in India and abroad.
What Ultra SMS asks for
| API key | Kaleyra.io, Developers, API Keys. |
|---|---|
| SID | Same page (your account SID). |
| Region and type | The region your account lives in (India accounts: api.in.kaleyra.io), and Transactional, Promotional or OTP. |
| Sender ID and Template ID | Your approved DLT header and template IDs. Your DLT Entity ID is linked to the Kaleyra account itself. |
Steps
- Sign in to Kaleyra.io and create an API key.
- Add your DLT details and approved sender IDs.
- In Ultra SMS add a gateway, choose Kaleyra, and paste the API key, SID and sender details.
- Send a test message with an approved template.
Good to know
- Sending to Indian numbers needs DLT registration: your Entity ID, an approved sender ID (header) and the Template ID of an approved content template. Ultra SMS has fields for all three. See the India DLT chapter of the manual.
Before you send through Kaleyra
Sending to Indian numbers needs DLT registration whichever gateway you use: your entity, approved sender IDs and approved templates, added to Ultra SMS so each message carries them. Kaleyra charges per message segment at its own rates, so check the segment counter and the cost estimate before you start. 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.
