Dynamic Ad Insertion pod serving VOD API

  • The Dynamic Ad Insertion API is used to request and track DAI on-demand streams.

  • There are different methods available for working with streams, including creating a stream, registering a stream, retrieving ad pods, and accessing ad pods metadata.

  • The create stream method directly creates a stream and provides all necessary resources for playback and tracking, while register stream registers a stream for later ad pod decisioning in a separate call.

  • The retrieve ad pods method is used after stream registration to get playable ad manifests.

  • The ad pods metadata method provides detailed information about ads, ad breaks, and media ID tags for tracking and UI display.

The Dynamic Ad Insertion API lets you request and track DAI on-demand streams.

Service: dai.google.com

All URIs are relative to https://dai.google.com.

Method: create stream

This method creates a stream directly from the device, returning all resources needed for the client application to play and track ads, and display UI elements.

Methods
create stream POST: /ondemand/pods/api/v1/network/{network_code}/stream

Create a DAI pod serving VOD session.

HTTP request

POST https://dai.google.com/ondemand/pods/api/v1/network/{network_code}/stream

Path parameters

Parameters
network_code string

The publisher's Google Ad Manager network code.

Request body

The request body is of type application/json and must contain a CreateStreamRequest object.

Response body

If successful, the response body contains a new CreateStreamResponse object.

Method: register stream

This method registers a stream on the Google DAI backend from the device, returning all the resources needed for the client application to track ads and display UI elements. Unlike the create stream method, this method does not return a playable ads manifest. Instead, this action is achieved in a separate server call: decision ad pods.

Methods
register stream POST: /ondemand/pods/api/v1/network/{network_code}/stream_registration

Registers a DAI pod serving VOD session.

HTTP request

POST https://dai.google.com/ondemand/pods/api/v1/network/{network_code}/stream_registration

Path parameters

Parameters
network_code string

The publisher's Google Ad Manager network code.

Request body

The request body is of type application/json and must contain a StreamRegistrationRequest object.

Response body

If successful, the response body contains a new StreamRegistrationResponse object.

Method: retrieve ad pods

This method follows a register stream call from a device and is necessary to retrieve playable ad manifests to stitch in content manifests.

Methods
decision ad pods POST: /ondemand/pods/api/v1/network/{network_code}/streams/{stream_id}/adpods

Decision ad pods for a DAI pod serving VOD session.

HTTP request

POST https://dai.google.com/ondemand/pods/api/v1/network/{network_code}/streams/{stream_id}/adpods

Path parameters

Parameters
network_code string

The publisher's Google Ad Manager network code.

stream_id string

The stream_id received from a stream_registration call.

Request body

The request body is of type application/json and must contain a AdPodDecisionRequest object.

Response body

If successful, the response body contains a new AdPodDecisionResponse object.

Method: ad pods metadata

This method returns all the information needed for the client app to track ads and render appropriate UI elements accurately.

Methods
ad pods metadata GET: /ondemand/pods/api/v1/network/.../metadata

Retrieve ad pods metadata for a specific session. This URL is returned in the StreamRegistrationResponse metadata_url attribute.

HTTP request

GET: /ondemand/pods/api/v1/network/.../metadata

Response body
