Required Fields

The minimum information required to create a channel using the serverside.ai API is:

• sourceManifestUrl - URL that points to a valid HLS or DASH manifest. The serverside.ai API can automatically detect which.

• name - A human-readable name for your channel.

• adSource - e.g.

{
    "system": "spotx", 
    "url": "https://search.spotxchange.com/vast/3.0/123456", 
    "params": {}
 }

• adSlateManifestUrl – e.g. https://xyxyxyxyxyxyxyyx.blob.core.windows.net/ch1234id99/adslate.m3u8

Optional fields

The following optional fields can also be supplied:

• apiKey – this is the API Key that secures access to the output stream, i.e. outputUri – if any such key is required.

• profile - an AMS (Azure Media Services) encoding profile is automatically generated by analyzing the manifest if not provided.

• state - defaults to 'disabled'

Process

First, the manifest is checked.

A 500 - 'Manifest Invalid' error will be reported if:

• The manifest cannot be found

• It is not a valid HLS or DASH manifest

• Its content is not correctly formatted so that the serverside.ai system can understand it

A 400 - 'No URL for the external system defined' error will be reported if:

• The system that provides the ad server information is not defined

• The system that provides the ad server information is incorrectly defined

Assuming this first check succeeds, the manifest is then analyzed, and the corresponding (AMS) profile, adSlateManifestUrl and adSource are generated (if not provided). adConditioner and outputUri are always automatically generated. These additional parameters are required to actually create the channel.

The channel is initially persisted using a 2nd API (SSAI API) which is connected to a REDIS cluster. Only when this step succeeds is the channel then written to the serverside.ai data store.

A channel is created in a `disabled` state and must be deliberately enabled, either in the Serverside.ai app or by an update call.

Errors

Errors from the analysis stage contain a JSON representation of all errors found in the analysis, to help in troubleshooting (See Detailed channel analysis errors ).
