SSG Administration Portal
Administer your global cloud instance from the SSG Administration Portal, or use the SSG Management API. Typical functions include:
- Configuration: Billing, routing, user access, operations, services and pricing plans.
- Customers: Accounts, balances, contacts, end-user portals, and SMPP or API accounts.
- Suppliers: SMSC connections, groups, route costs and maintenance windows.
- Routing: MSISDN caching, routing strategies, SMSC groupings and route analysis.
- Reporting: Customers, networks, suppliers, delivery latency, margin, cost and revenue.
- Financial: Invoices, payment reminders, credit notes, pre-pay and post-pay balances.
- Security: Firewall rules by MSISDN, source address, content and parameters.
- CDRs: Customer and supplier CDRs including revenue, network, parameters and content.
txtConsole and APIs
Give your customers the brandable txtConsole portal for sending and receiving SMS without API integration — useful for marketing, onboarding, appointment reminders, staff communication and support. Applications that need an API can use SMPP, REST or HTTP, with TLS and access controls.
Cloud first
The cloud platform is the usual starting point: globally distributed nodes, no infrastructure to run, and a trial you can request in minutes. On-premises deployment is available if you need the switch inside your own environment. Pricing is based on message volume, with monthly rental or perpetual licence options and volume or term discounts.
