7 </ul><p>Today, we’re excited to announce Klaviyo’s API endpoint expansion enabling developers to build a wider array of personalized experiences.</p>

8 <p>We’re excited to release full CRUD functionality for our Tags API (in general availability), Data Privacy API (in general availability), and Campaigns API (open beta).</p>

9 <h3>Tags API</h3>

10 <ul><li><strong>Overview:</strong>Klaviyo’s tags can be used to group related Klaviyo components (e.g. group different types of campaigns such as product releases or announcements; group different lists together under a theme, such as holiday lists). Now you can integrate existing tags-based workflows into automations you build with our APIs by accessing tags, tag groups, and all related tagged items - like flows, campaigns, and more.</li>

11 <li><strong>Example:</strong>Brands can effectively access, organize, and update tags by using new CRUD operations to manage resources including campaigns and flows based on tags and tag groups.</li>

12 </ul><h3>Campaigns API</h3>

13 <ul><li><strong>Overview:</strong>Developers will soon be able to programmatically create, update, and send email campaigns as well as make updates and check deliverability of said campaign during launch.</li>

14 <li><strong>Example:</strong>As a partner working with a brand, you can now programmatically create, update, and send email campaigns, make updates and check deliverability of campaigns during launch ensuring it aligns with your launch plan.</li>

15 </ul><h3>Data Privacy API</h3>

16 <ul><li><strong>Overview:</strong>Begin deleting a brand’s subscriber data depending on their affiliated marketing channel and company.</li>

17 <li><strong>Example:</strong>To adhere to GDPR, you can now delete profile records for GDPR “right to be forgotten” requests to stay compliant with your marketing messaging.</li>
