Yahoo Search in Apps

At Yahoo, we’re always looking for ways to streamline and simplify products for our customers. With this focus in mind, we will discontinue the BOSS JSON Search API on March 31, 2016.

Access to the BOSS APIs will continue until March 31, 2016. Moving forward, customers leveraging the BOSS JSON Search API can instead use YPA, a Javascript Solution that provides algorithmic web results with search ads for publishers who manage their own search engine results pages (SERPs). Click here to apply or learn more about YPA, or if you are working with a Yahoo Partner Manager, they can help you explore your options.

Sponsored Search Ads Program

Qualified developers can receive advertising in the same BOSS call as other content. In order to participate, you will need to provide some details about your product, including information about your traffic sources, UI framework, and implementation. Once your product is approved, you will be able to deploy Yahoo Sponsored Search ads to generate revenue.

Our partner DDC will work with you to help set your service up. Please note that in signing up for the Sponsored Search ad program, you will be entering into a contract with DDC, not Yahoo. DDC will handle all ad-related financial payments and support. To get started, (1) create an APP and then (2) fill out this form. You must provide your BOSS APP ID in the form or it will delay approval.

Get Started

Get your API Keys

Start by creating a project and adding billing information. This will give you a Consumer Key and Secret which are needed for using the API.

Copy Example Code

We have code examples in different languages to get you up and running as quickly as possible.

Build and Launch

Replace your Consumer Key and Secret in the code you copied and run the example code. When your app is ready to use, tell other developers what you have built in our Forums.
