Option 1: Client’s API Services (recommended)

What is it? Connects the creative directly to the client’s database. The client will hold the data.

What do we need from the client? Documentation on how to access and use their API. Each API is unique and we need a key on how to access it and which endpoints we’ll be referencing for our creative specifically.

Can PII information be used? Yes

Option 2: HTTP POST Method

What is it? Appends the form-data inside the body of the HTTP request and sends it to the client’s endpoint/server.

What do we need from the client? 1)The endpoint url 2) An example of the data that should be sent to that endpoint (i.e., a sample object). 3) Confirmation that this endpoint is able to accept data from client-side communication (no server-server authorization tokens)

Can PII information be used? Yes

Option 3: HTTP GET Method

What is it? Appends the form-data to the URL query string and sends it to the client’s server upon submission.

What do we need from the client? The parameters that go into the url and what their expected values should be.

Can PII information be used? No

NOTE: A disclaimer on all creative is required. Additionally, creative must be approved by Yahoo Ad Policy prior to launch.
