These are the v2 docs. For the current version, look here.

signed_off_by

A pro plan is required to use this feature on private repos.

Require that all commits in the PR are signed-off-by their git author (i.e. commit message contains Signed-off-by: Dave Gaeddert <dave.gaeddert@pullapprove.com>, with an email address that matches the author).

Typically used to help manage compliance with http://developercertificate.org/.

Note: This currently only checks the latest 250 commits on a PR, if you have PR's larger than that, please let us know.

Example usage:

requirements:
        signed_off_by:
            required: true
