Get Akamai SIEM logs to ELK

Hi,

We want to ingest SIEM logs from akamai to Logstash, then Elasticsearch.
To access SIEM logs, we have created akamai API credentials and have gotten SIEM connector details. They include:
client_secret =
host = xyz.luna.akamaiapis.net
access_token =
client_token =
userid =
password =

What input plugin will be suitable to pull those logs into Logstash?
Or it would be wise to make an API to get those logs onto a server?

Thanks,
Shubhangi.
