Endpoint policy fields
You must assign a channel policy to enable content to flow into your channel from sources outside of your account.
Under Endpoint policy, choose an endpoint policy to enable content to flow into your channel from sources outside of your account. For more information about policies, see Resource-based policy examples.
Don't attach a policy - Restrict access to only those who have access to this account's credentials.
Attach a custom policy - Define your own policy and restrict access to as few or as many as you want. Enter a valid JSON object with the same structure as other IAM policies. The policy should follow the standard security advice of granting least privilege, or granting only the permissions required to perform a task.
Attach a public policy - Accept all incoming client requests to a channel's output. Enter a valid JSON object with the same structure as other IAM policies.
