 The following Terraform variables are required:
 
-- `splunk_access_token`: Observability Cloud Access Token
-- `splunk_api_token`: Observability Cloud API Token
-- `splunk_rum_token`: Observability Cloud RUM Token
-- `splunk_realm`: Observability Cloud Realm e.g. `eu0`
-- `splunk_hec_url`: Splunk HEC URL. Do not use a `raw` endpoint, use the `event` endpoint so logs process correctly.
-- `splunk_hec_token`: Splunk HEC Token
+- `swipe_id`: [SWiPE ID](https://swipe.splunk.com/) for the instance
 - `splunk_index`: Splunk Index to send logs to. Defaults to `splunk4rookies-workshop`.
