EUID Integration Overview for JavaScript
This guide is an overview of integration options for publishers who want to integrate with EUID and generate EUID tokens (advertising tokens) using the SDK for JavaScript.
For a summary of all web options, including Prebid.js and additional SDK options, see Web Integration Overview.
Introduction
EUID provides an SDK for JavaScript that supports the following:
For additional flexibility, EUID also provides alternative methods for some of the features and complementary products, such as a Prebid integration.
Client-Side or Client-Server Integration
The options for integrating with EUID using the SDK for JavaScript are summarized in the following table. Choose the option that's best for you.
| Scenario | Option | Integration Guide |
|---|---|---|
| You have access to personal data on the client side and want to do front-end development only. | Client-side integration | Client-Side Integration Guide for JavaScript |
| You have access to personal data on the server side and can do server-side development, or you are using a Private Operator. | Server-side integration | Client-Server Integration Guide for JavaScript |
Generating the EUID Token
Depending on access to personal data, there are two methods to generate EUID tokens using the SDK for JavaScript: client-side or server-side.
From the table in Client-Side or Client-Server Integration, determine which option is best for you, and then follow the applicable integration guide.
Refreshing the EUID Token
The SDK for JavaScript includes automated token refresh.
Storing the EUID Token in the Browser
The client-side option stores data using local storage. The client-server option uses local storage by default, but you can also choose to use a cookie instead. For details, see EUID Storage Format in the SDK for JavaScript Reference Guide.
The cookie size can be significant, which could be a problem. However, if local storage is not an option, this is one possible approach.
Passing the EUID Token to the Bidstream
The JavaScript SDK manages generating, refreshing, and storing the EUID token, but it does not manage passing the token to the bidstream.
You can pass the token into the bidstream using any option you choose—for example, Prebid.js. For some suggestions, see Pass the Token Into the Bidstream in the Web Integration Overview.
