For partners using Gooru Search Index, this API allows for periodic update of the same by identifying content items deleted / dropped from Gooru Search index. Gooru maintains the deleted items index for a period of one year.

1. Authentication

All Gooru API calls must be authenticated using access tokens. To acquire an access token you need an Client Id and Client Secret key. Contact support@gooru.org for the necessary detail.

Authenticating with a Client Id and Client Key

Once you have a ClientId and Client Key, making API calls is very easy and simple. Please follow the below steps:

Call to obtain access token API with header “Authorization”.
Header name “Authorization” and header value “Basic [access_token]”
Header value is “Basic base64encode(username:password)” - meaning have to encode(base64) “username:password” string and pass it to header.
From the the response, extract the “access_token” field that will be needed for subsequent API

curl -i -H "Content-Type: application/json" -H "Authorization: Basic b2liZ2FuZzlAZ29vcnUub3JnOmRvbjEyMzQ=" -d '{ "client_key": "c2hlZWJhbkBnb29ydWxlYXJuaW5nLm9yZw==", "client_id": "ba956a97-ae15-11e5-a302-f8a963065976", "grant_type": "credential" }' -X POST http://gooru.org/api/nucleus-auth/v1/token
