**Table 1** Path Parameters
Parameter	Mandatory	Type	Description
project_id	Yes	String	Project ID. For details about how to obtain the project ID, see "Obtaining a Project ID".

**Table 2** Query Parameters
Parameter	Mandatory	Type	Description
flow_id	Yes	String	Flow ID
source_name	Yes	String	Flow source name

Request Parameters

**Table 3** Request header parameters
Parameter	Mandatory	Type	Description
X-Auth-Token	No	String	User token. This parameter is mandatory when token authentication is used. The token can be obtained by calling the IAM API used to obtain a user token. The value of X-Subject-Token in the response header is the user token.
Authorization	No	String	Authentication information. This parameter is mandatory for AK/SK authentication.
X-Sdk-Date	No	String	Request time. This parameter is mandatory for AK/SK authentication.
X-Project-Id	No	String	Project ID. This parameter is mandatory for AK/SK authentication.

**Table 4** Request body parameters
Parameter	Mandatory	Type	Description
source	Yes	FlowSource object	Source stream information

**Table 5** FlowSource
Parameter	Mandatory	Type	Description
source_listener_address	No	String	Ingest URL
source_listener_port	No	Integer	Port that pulls streams. 2077 and 2088 are not allowed.
stream_id	No	String	streamid of SRT stream pull
min_latency	No	Integer	Minimum latency, in millisecond.
cidr_whitelist	No	Array of strings	CIDR IP whitelist for stream push
description	No	String	Description
protocol	Yes	String	Protocol. The value can be srt-caller or srt-listener.
name	Yes	String	Input resource name
decryption	No	FlowSourceDecryption object	Flow decryption information in StreamConnect.
health_status	No	String	Indicates the stream push status. The options are as follows: CONNECTED: The stream is being pushed; DISCONNECTED: The stream push is interrupted.

**Table 6** FlowSourceDecryption
Parameter	Mandatory	Type	Description
algorithm	No	String	Encryption algorithm. The value can be aes128 (AES-128), aes192 (AES-192), or aes256 (AES-256).
key_type	Yes	String	Key type. The value can be speke (obtaining keys using the SPEKE protocol), static-key (static key), or srt-password (SRT key). Currently, only srt-password is supported.
passphrase	Yes	String	SRT decryption key, which is used by a flow to decrypt SRT streams.
