@meagharty sorry for the late review here. Just to clarify, this is going to generate a new token just for the gtfs_creator CI process? How do we get that token out of Arrow so we can add it to the secrets in the gtfs_creator repo?

@bklebe The tokens are committed to the database. Once the code is deployed and the migration runs, I was going to submit an infra request to query the database to fetch the token via the email and add it to the secrets.
