Creates a source for a MediaConnect flow.
Operation description
- When the specified flow ID is not available, an error code is returned.
- A flow can have only one source.
Source type
- RTMP-PUSH: An input that you can push to the returned URL over the RTMP protocol.
- RTMP-PULL: An input that the MediaConnect flow pulls from the specified server over the RTMP protocol.
- SRT-Listener: An input that you can push to the returned URL over the SRT protocol.
- SRT-Caller: An input that the MediaConnect flow pulls from the specified server over the SRT protocol.
- Flow: An input that uses the output of another upstream flow. You must specify an upstream flow and its output. The output type of the upstream flow must be SRT-Listener or RTMP-PULL. By default, a dedicated line is used when flows are cascaded. This allows for cross-region distribution among multiple flows.

Authorization information
The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:
- Operation: the value that you can use in the Action element to specify the operation on a resource.
- Access level: the access level of each operation. The levels are read, write, and list.
- Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- For mandatory resource types, indicate with a prefix of * .
- If the permissions cannot be granted at the resource level,
All Resourcesis used in the Resource type column of the operation.
- Condition Key: the condition key that is defined by the cloud service.
- Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
