### This week on the X Developer Platform

A quick recap of what shipped this week across the X Ads API.

**New features**

- **[Lead Generation API](/x-ads-api/lead-generation)** — Create and manage native lead forms, attach a form to a card with the `LEAD_FORM` destination, and export submitted leads as JSON, CSV, or XLSX. Requires the Campaign user permission; lead exports are limited to account administrators.
- **[Conversion API server-side template for Google Tag Manager](/x-ads-api/measurement/gtm-server-side)** — Send website conversions through the official **X Ads Conversion API (Official)** tag in a Google Tag Manager server container, with no Conversion API request code to write. The template is published in the [GTM Community Template Gallery](https://tagmanager.google.com/gallery/#/owners/twitter/templates/x-ads-conversion-api-gtm-template).

**Updates**

- **`REGIONS` segmentation for asynchronous analytics** — Async analytics jobs now accept `REGIONS` as a `segmentation_type` for regional breakdowns. The `country` parameter is required when requesting this segmentation. See [Metrics and Segmentation](/x-ads-api/analytics#metrics-and-segmentation) for the full list of supported types.
