Send OTP codes and SMS campaigns via Twilio

How it works

Twilio is one of two natively supported SMS gateways in Powerlynx, the other being SMSPortal. To connect, create a Twilio account and obtain three values from the Twilio Console: Account SID, Auth Token, and a Twilio phone number (From number). In Powerlynx under Config → SMS, add a new gateway and select Twilio as the type.

The Powerlynx fields map to Twilio values as follows: Account SID → both the “Account SID” and “API key” fields; Auth Token → “API secret”; Twilio phone number → “From”. For more secure authentication, Twilio also supports creating a dedicated API key of type Standard — this can be used in the API key field instead of the Account SID.

Once connected, Powerlynx routes all outbound SMS through Twilio — OTP codes, mass campaigns, voucher delivery, and 1:1 messages. All messages are logged under Logs / SMS Logs.

Fallback configuration

Multiple SMS gateways can be active simultaneously. The top gateway in the list is primary — any other enabled gateway is fallback. If Twilio fails to send, Powerlynx automatically routes through the fallback gateway. Order is changed by drag and drop.

What this integration provides

• OTP SMS delivery for phone number verification at the captive portal.
• Mass SMS campaigns — service announcements, promotions, bulk notifications.
• Voucher code delivery via SMS for offline redemption.
• 1:1 SMS from customer profiles in Powerlynx.
• Primary or fallback gateway.
• Full delivery status and audit trail under Logs / SMS Logs.
• Balance monitoring with email and dashboard alerts.

Credentials required

Account SID, Auth Token, and From number from the Twilio Console at console.twilio.com. Alternatively: Account SID as API key + Auth Token as API secret + dedicated Standard API key for more secure auth.

Requirements

• Twilio account.
• Account SID, Auth Token, and an active Twilio phone number with SMS capability.
• OTP verification for the splash page is optional — enabled or disabled per splash page.
