REDIS_TLS_URL and REDIS_TEMPORARY_URL are deprecated for Heroku Key-Value Store add-ons

Change effective on 04 December 2024

In July 2024, we announced the deprecation of REDIS_TLS_URL config var for all mini Heroku Key-Value Store add-ons. The REDIS_TLS_URL and REDIS_TEMPORARY_URL config vars previously available for these add-ons are now deprecated, and we’ll begin removing these config vars starting today.

All Key-Value Store add-ons now require secure TLS connections using the REDIS_URL config var. If your apps continue to use REDIS_TLS_URL or REDIS_TEMPORARY_URL to connect, you’ll see issues in your connections.

See Connecting to Heroku Key-Value Store for examples on the most popular Redis clients in all of Heroku’s supported languages.
