POST /20180418/streams/<streamId>/messages Host: streaming-api.us-phoenix-1.oraclecloud.com <authorization and other headers> "value": "VGhlIHF1aWNrIGJyb3duIGZveCBqdW1wZWQgb3ZlciB0aGUgbGF6eSBkb2cu" }, "value": "UGFjayBteSBib3ggd2l0aCBmaXZlIGRvemVuIGxpcXVvciBqdWdzLg==" } https://docs.cloud.oracle.com/en-us/iaas/api/#/en/streaming/20180418/Message/PutMessages
