This step updates a Splunk On-Call timeline with information from a Relay workflow. It will update the account timeline and optionally, if an entity_id for an existing incident is supplied to the step, will associate the update with that incident. It posts as INFO level messages. It requires that you enable the REST integration on your Splunk On-Call account; doing so will generate a unique URL that you should store as a Secret named endpointURL in Relay, associated with this workflow.
See the step.schema.json file for the formal specification of how to use this step.
See the examples section in step.yaml for examples of how to use this step in a workflow.
