Logstash to push Filebeat logs to Datadog

I am currently working on configuring Logstash to push Filebeat logs to Datadog. I need some clarification regarding the necessity of deploying the Datadog Agent in our cluster for this purpose.

Specifically, I would like to know if it is required to deploy the Datadog Agent to facilitate the log pushing, or if Logstash can directly connect to Datadog using the API key provided in the configuration.
