Hi there,

Changing the configuration for a managed Redis cluster can be achieved via the DigitalOcean API as described here in the docs:

https://docs.digitalocean.com/reference/api/api-reference/#operation/databases_patch_config

The request will look as follows:

curl -X PATCH \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $DIGITALOCEAN_TOKEN" \
  -d '{"config": {"redis_notify_keyspace_events": "YOUR_VALUE_HERE"}}' \
  "https://api.digitalocean.com/v2/databases/YOUR_DB_ID_HERE/config"

The redis_notify_keyspace_events value should be a string <= 32 characters.

Hope that this helps!

Best,

Bobby
