# Check WhatsApp Session This step allows you to verify if the 24-hour contactable session for the contact is valid. If the session is not found, you can dynamically route to another step where a template message can be initiated. Please note, this step is applicable only for WhatsApp Official & Cloud Channels. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
