SMS providers and delivery queue

Choose the provider

Select one default SMS provider for system functions or disable SMS explicitly. Available integrations can include ISP Billing, Clickatell, BeSMS, Skebby, SMS Hosting or SmsTools, SMSAPI, and GatewayAPI according to contract.

Disabling causes send requests to be skipped intentionally. Changing provider does not migrate credit, approved senders, whitelists, or provider history.

Provider-specific credentials

Keep credentials server-side, verify environment and balance, and never copy values between providers merely because field names look similar.

Sender, domains, and links

The sender name must be approved by the provider and comply with destination-country rules. When messages link to Customer Area, configure and verify the final custom domain; GatewayAPI may require that domain in an anti-fraud whitelist.

Test message

After saving the default provider, use Send test message with an authorized number in international format. This performs a real provider request and may consume credit.

A successful response proves provider acceptance, not handset delivery or reading. Verify balance, provider log, delivery state when available, and the destination phone.

Retry, remove, and clear

Clear queue removes all pending or failed messages in scope and can interrupt invoice, ticket, reminder, or marketing automation. Review filters, volume, business impact, and duplicate risk before confirmation.
