Template Management
Create a Template
On the Message Center -> Template Management page, click the [Create Template] button to open the template creation page:
Follow the prompts in the image to enter the template name, template ID, brand name, one-time password length, one-time password expiration time, and other information required for EngageLab OTP configuration.
The template ID must not exceed 30 characters, supports only English letters, numbers, and underscores, and must be unique within the application. This value must be provided in the OTP sending API.
The one-time password length supports 4 to 10 characters, with three possible combinations: numbers, uppercase English letters, or numbers and uppercase English letters.
The validity period of the one-time password can be configured as one of the following options: 1 minute, 5 minutes, or 10 minutes. If you need a longer validity period, please contact sales or online customer service, or send an email to support@engagelab.com to apply.
Sending Policy Configuration
If you use the SMS channel to send OTP verification codes, select SMS for the sending policy:
There are two optional template style settings: Add security advice and Add one-time password validity period, which you can configure as needed.
The configuration for other channels is similar to the SMS channel configuration.
In addition, EngageLab OTP also supports an intelligent channel fallback strategy. For example, when the WhatsApp channel is not delivered or delivery times out, the system automatically resends through the SMS channel. If the SMS channel still encounters non-delivery or a delivery timeout, the Voice channel is used for resending.
When the Automatically resend on failure WhatsApp->SMS->Voice policy is selected, you need to review the template content for the three channels in the following order: WhatsApp -> SMS -> Voice.
