60407: Authentication Token Error

This error occurs when Verify cannot generate an AccessToken for a Verify Push enrollment request. Use the Verify AccessToken resource only for Verify Push enrollment and registration flows. This resource supports only the push factor type.

• You sent a factorType value that Verify Push does not support. The Verify AccessToken resource accepts only push.
• You tried to use the Verify Push AccessToken flow for a non-push verification flow. The AccessToken resource is for creating or registering a Verify Push Entity or Factor, not for starting SMS, voice, WhatsApp, email, or other Verify channel verifications.
• You attempted to reuse an access token pattern from another Twilio SDK product. Verify Push AccessToken values cannot be reused between Voice, Chat, or Video style token flows.

• Set factorType to push when you create the AccessToken.
• Generate the token from your backend for the correct Verify Service and return the token, identity, and Verify Service SID to your client application as part of your Verify Push enrollment flow.
• If you need SMS, voice, WhatsApp, email, or another non-push Verify channel, start a Verification with the appropriate channel instead of creating an AccessToken.
• Use an immutable identity value from your own system when you create the token, such as a UUID, GUID, or SID.
