The 2070 - Invalid Flow Version error occurs when the version of a flow you’re using is either invalid or expired. WhatsApp frequently updates flow versions, and older versions may no longer be supported. This guide explains the causes of this error and provides step-by-step solutions to resolve it.

What Causes the '2070 - Invalid Flow Version' Error?

  1. Using an Expired Flow Version: WhatsApp periodically deprecates older flow versions. If a flow version is outdated, it may no longer be compatible with the API.
