Skill Rollback REST API Reference


Use the Skill Rollback REST API to revert your skill to a previous live version without having to submit the skill for recertification. For example, if your new skill version introduced a bug or any other unintended behaviors, you can roll back the skill to a previous version.

To roll back a skill, your skill must meet the rollback eligibility requirements. For more details, see Skill Rollback.

You can roll back a skill in the Alexa developer console also. For details, see Roll back your skill by using the console. Or, you can roll back a skill by using the Alexa Skills Kit (ASK) Command Line Interface rollback-skill command.
