Overview

This node checks if a contact exists based on a provided phone number within a specified session. It is useful for verifying the presence of a contact in a system before performing further actions, such as sending messages or updating contact details. For example, it can be used in customer support workflows to confirm if a customer's phone number is registered.

Use Case Examples

1. Check if a phone number exists in the contact list before sending a promotional message.
2. Verify contact existence during onboarding to avoid duplicate entries.
