Editing Messaging flows (section)

=== Contact variables ===
Contact variables come from a contact’s information. By default, each contact comes with five variables:
* First name
* Last name
* Phone number
* Email
* URL

Additionally, you can have as many variables as needed as contact attributes. You can use these contact attributes in messaging flows, or the messaging flow can dynamically change them.

A contact always precedes the contact variable, followed by the variable name. For example, if you want to use the contact’s first name, you would use %contact.first_name%.
