Video Cloud SSAI Ad Tag Validation

In this topic, you will learn how to trace ad calls specified with Server-Side Ad Insertion (SSAI).

Overview

To help with debugging of server-side ads, Dynamic Delivery with SSAI provides API endpoints to track ad calls.

To debug server-side ads with your video content stored in Video Cloud, follow these steps:

  1. Review general information for API path and authorization
  2. Run a trace for an ad configuration
  3. Retrieve trace details

General information

The following information pertains to all SSAI API requests.

Base URL

The base URL for the SSAI API is:

  https://ssai.api.brightcove.com/v1

Account path

In all cases, requests will be made for a specific Video Cloud Account. So, you will always add the term accounts followed by your account id to the base URL:

  https://ssai.api.brightcove.com/v1/accounts/your account id

Authorization

API requests require an Authorization header:

  Authorization: Bearer your access token

The access_token is a temporary OAuth2 access token that must be obtained from the Brightcove OAuth service. For details on how to obtain client credentials and use them to retrieve access tokens, see the Brightcove OAuth Overview.

Operations

When you request client credentials, you will need to specify the type of account access or operations that you want. The following is a list of the currently supported operations for the SSAI API:

  • SSAI data:

    video-cloud/ssai/read
    video-cloud/ssai/all

Run a trace for an ad configuration

To run a trace for an ad configuration, follow these steps:

Gather information

Gather the following information for the body of your API request:

Parameter Type Description
account_id String User account id
playback_config Object Fields are defined in the Configuration field details section of the SSAI API document.
title_metadata Object Tells the system how long your content is in order to generate the correct ad response.

For example, the following tells the system that the content is 1 minute long. This is used to insert ads accordingly. 
  "title_metadata": {  "duration": "1m" }
videocloud_metadata Object Optional.
Needed only if you are using template variables that reference metadata fields. These are defined in the Ad variables section of the SSAI API document.

Request

Create a trace for an SSAI ad configuration.

Method POST

Retrieve trace details

Once you have run an ad trace as shown in the previous section, you can retrieve detailed information about the trace using the session Id.

The session_id specifies the caching session. Each session has its own length based on the video content length. You can get the id from the response for the API call in the previous step.

The Session id can be found in the VMAP responses from the previous section. Here is an example:

  <bc:BrightcoveDebug sessionID="your session id"></bc:BrightcoveDebug>

Request

To retrieve ad-call trace information by supplying a session id, use a GET request similar to the following:

Method GET
URL https://ssai.api.brightcove.com/v1/accounts/{account_id}/ssai_traces/{session_id}/ad_calls
Headers Authorization: Bearer access_token (see Getting Access Tokens)
