International Lark tenant cannot access /open-apis/slides_ai/v1/xml_presentations endpoint (404 despite published app and granted scopes) #1033

Description

We are currently building an AI workflow system on top of Lark/Feishu for corporate training, project management, and document/presentation automation.

Our application has already been:

  • published successfully,
  • granted the required Slides/Docs scopes,
  • authorized within our tenant,
  • and can access other Open APIs normally.

However, requests to the following endpoint consistently return 404:

/open-apis/slides_ai/v1/xml_presentations

We suspect there may be a difference between:

  • International Lark tenants
  • and China-region Feishu tenants

regarding Slides AI / XML Presentation API availability.

This does not appear to be a normal permission configuration issue because:

  • the app is already published,
  • access tokens work correctly,
  • scopes are already granted,
  • and other APIs function normally.

Only this Slides AI endpoint returns 404.

What we are trying to build

We are building:

  • AI-assisted document workflows,
  • AI-generated presentation workflows,
  • corporate training/project-management automation,
  • and presentation generation pipelines integrated into Lark.

The intended workflow is:

  1. User submits structured content
  2. AI generates presentation structure/content
  3. System creates/editable Slides inside Lark/Feishu

Questions

We would appreciate clarification on the following:

  1. Is /open-apis/slides_ai/v1/xml_presentations supported for International Lark tenants?
  2. Does this endpoint require whitelist access?
  3. Is it currently China-region-only?
  4. Is there an application process to enable access?
  5. Are there recommended alternative APIs for AI-generated presentation workflows?

Current behavior

  • App published successfully
  • Required scopes granted
  • Access token generation works
  • Other APIs work normally
  • Only this endpoint returns 404

Expected behavior

One of the following:

  • endpoint works for International Lark tenants,
  • whitelist/application process is documented,
  • or an alternative API path is recommended.

Additional information available

We can provide:

  • App ID
  • Tenant info
  • Request IDs
  • Request logs
  • Postman/curl examples
  • permission screenshots
  • reproduction steps

标题

国际版 Lark 租户无法访问 /open-apis/slides_ai/v1/xml_presentations 接口(应用已发布且权限已授权,但持续返回 404)

问题描述

我们目前正在基于 Lark/飞书开发一个 AI 工作流系统,用于企业培训、项目管理以及文档/演示文稿自动化。

我们的应用目前已经:

  • 成功发布,
  • 已添加并授权相关 Slides / Docs 权限,
  • 已在租户中完成授权,
  • 并且其他 Open API 均可正常访问。

但以下接口持续返回 404:

/open-apis/slides_ai/v1/xml_presentations

我们怀疑国际版 Lark 与中国区飞书之间,在 Slides AI / XML Presentation API 的开放能力上存在差异。

目前看起来不像是普通权限配置问题,因为:

  • 应用已经发布,
  • Access Token 获取正常,
  • 权限范围已经授权,
  • 其他 API 均正常工作,
  • 只有该 Slides AI endpoint 返回 404。

我们想实现的功能

我们正在构建:

  • AI 辅助文档工作流,
  • AI 自动生成演示文稿工作流,
  • 企业培训 / 项目管理自动化,
  • 与 Lark 集成的演示文稿生成能力。

预期流程:

  1. 用户提交结构化内容
  2. AI 生成演示文稿结构与内容
  3. 系统在飞书/Lark 内生成可编辑 Slides

希望确认的问题

希望协助确认以下事项:

  1. /open-apis/slides_ai/v1/xml_presentations 是否支持国际版 Lark 租户?
  2. 当前接口是否需要白名单?
  3. 是否目前仅对中国区飞书开放?
  4. 是否有正式申请开通流程?
  5. 是否有推荐的替代 API 方案用于 AI Slides 工作流?

当前现象

  • 应用已成功发布
  • 权限已授权
  • Access Token 获取正常
  • 其他 API 正常
  • 仅该 endpoint 返回 404

期望结果

以下任一结果均可:

  • 国际版 Lark 可正常调用该接口;
  • 提供白名单/申请流程;
  • 或提供替代 API 方案。

可提供的额外信息

我们可以进一步提供:

  • App ID
  • Tenant 信息
  • Request ID
  • 请求日志
  • Postman/curl 示例
  • 权限截图
  • 复现步骤
