Authentication nodes

Twilio Verify Sender node

Initiates a Twilio Verify request to send a one-time passcode to the user’s device as an additional authentication factor.

If you do not enable the Request Identifier property, make sure the shared node state has a userIdentifier field set with a valid phone number or an email ID when the flow reaches this node.

Follow this node with the Twilio Verify Collector Decision node in the authentication flow.

Phone numbers must contain the country code and can optionally contain special characters. The node removes all special characters before making the Twilio Verify request.

Valid identifiers include +15553231234 or 1(555)323-1234. Invalid identifiers include (555) 323-1234 as the country code is missing.

Call

The same rules apply for phone numbers.

Email

To use this channel, first integrate the Twilio Verify with SendGrid services, as described in Send Email Verifications with Verify and Twilio SendGrid.

WHATSAPP

The same rules apply for phone numbers.

Request Identifier

Whether to prompt the user for their identifier.

Optionally, this node can prompt the user for their identifier. By default, the authentication flow shared node state must contain a userIdentifier field that holds a valid phone number or email address.

Default: disabled
