A business SMS service that uses your account reference, login email and an API password.
What Ultra SMS asks for
| Account reference | Your Esendex account: EX followed by digits. |

| API password | Generate it in your Esendex profile. |
| From (optional) | Up to 11 characters or a number. |
Steps
- Sign in to Esendex and generate an API password in your profile.
- Copy your account reference (EX followed by digits).

- Send a test message to your own phone before you start a campaign.
Good to know
Before you send through Esendex
Esendex 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.
