Heroku API Certificate Change


On March 8, 2023 at 17:00 UTC, Heroku will change the certificate for api.heroku.com from a DigiCert provided certificate to a Let's Encrypt provided certificate. This may affect your Heroku apps if they satisfy any of the following conditions:

  1. Pins custom ICA/Root certificates
  2. Hard-codes the acceptance of ICA/Root certificates
  3. Bundles their own trust store

If your app does any of the above, you'll likely have issues interacting with the Heroku API (api.heroku.com).
