Alter Product Public API 集成

身份验证与基础 URL

https://alterproduct.com/public-api/v1

在电商设置面板中创建 API 凭据。Access Token 仅显示一次，请立即将其存储到后端的密钥存储中。

将 Access Key 和 Access Token 保存在你的服务器上。需要身份验证的端点会拒绝包含 Origin 或 Referer 请求头的浏览器来源调用。

凭据可以设置权限范围。使用 GET /auth/check 验证当前店铺、套餐功能以及凭据返回的权限范围。

x-alter-access-key: YOUR_API_KEY
x-alter-access-token: YOUR_API_TOKEN

连接测试

在正式集成中启用同步或嵌入功能之前，请使用身份验证检查端点。

GET https://alterproduct.com/public-api/v1/auth/check

请求示例（fetch）

const response = await fetch('https://alterproduct.com/public-api/v1/auth/check', {
  method: 'GET',
  headers: {
    'x-alter-access-key': process.env.ALTER_ACCESS_KEY,
    'x-alter-access-token': process.env.ALTER_ACCESS_TOKEN
  }
});

const payload = await response.json();

if (!response.ok) {
  throw new Error(payload?.code || payload?.error || `Alter API ${response.status}`);
}

console.log(payload);

响应示例

{
  "ok": true,
  "message": "success",
  "storefrontId": 12,
  "userOwnerId": 34,
  "credentialId": 56,
  "scopes": ["orders:read", "orders:write", "products:read"],
  "plan": {

    }
  }
}

下面的辅助函数供后续示例使用。它基于原生 fetch，可在 Node.js 18+ 或任何提供 fetch 的服务器运行时中运行。

const ALTER_API_BASE = 'https://alterproduct.com/public-api/v1';

const authHeaders = {
  'x-alter-access-key': process.env.ALTER_ACCESS_KEY,
  'x-alter-access-token': process.env.ALTER_ACCESS_TOKEN
};

async function alterFetch(path, options = {}) {
  const response = await fetch(`${ALTER_API_BASE}${path}`, {
    ...options,
    headers: {
      ...authHeaders,
      ...(options.body ? { 'Content-Type': 'application/json' } : {}),
      ...options.headers
    }
  });

  const payload = await response.json().catch(() => null);

  if (!response.ok) {
    throw new Error(payload?.code || payload?.error || `Alter API ${response.status}`);
  }

  return payload;
}

嵌入会话与运行时初始化

在服务器上创建短期嵌入令牌，传递给 iframe／运行时，然后让运行时使用 Bearer 令牌调用 bootstrap。

请求示例（fetch）

const session = await alterFetch('/embed/session', {
  method: 'POST',
  headers: {
    'x-alter-client-fingerprint': '9f1b7a5e4b3c2d1f9f1b7a5e4b3c2d1f'
  },
  body: JSON.stringify({
    runtimeBindingId: 42,
    origin: 'https://yourstore.com'
  })
});

const bootstrapResponse = await fetch('https://alterproduct.com/public-api/v1/runtime/bootstrap', {
  method: 'GET',
  headers: {
    Authorization: `Bearer ${session.token}`
  }
});

const bootstrap = await bootstrapResponse.json();
console.log({ session, bootstrap });

说明

await alterFetch('/embed/session', {
  method: 'POST',
  body: JSON.stringify({
    tool: 'customizer',
    origin: 'https://yourstore.com',
    orderId: 123
  })
});

await alterFetch('/embed/session', {
  method: 'POST',
  body: JSON.stringify({
    tool: 'viewer',
    origin: 'https://yourstore.com',
    designId: 381
  })
});

  "expiresIn": 900,
  "kid": "1",
  "mode": "design",
  "runtimeBindingId": 42,
  "runtimeType": "customizer"
}

Runtime bootstrap

{
  "runtimeBindingId": 42,
  "designId": 381,
  "productId": "wc_123",
  "runtimeType": "customizer",
  "storageMode": "wordpress_local",
  "manifestUrl": "https://yourstore.com/wp-content/uploads/alter/381/manifest.json",
  "assetBaseUrl": "https://yourstore.com/wp-content/uploads/alter/381/",
  "manifestHash": "a3b1...",
  "planCapabilities": {
    "viewer": true,
    "configurator": true,
    "customizer": true
  },
  "cartKey": null,
  "cartMode": null,
  "orderId": null
}

3D 模型生成器

生成器导入端点接受只读的服务器间请求。这些请求需要标准 API 请求头、embed:session:create 权限范围以及有效的订阅方案。导入授权不会创建编辑器会话，也不会消耗该会话的月度配额。打开编辑器时使用的 monthlyEmbedTokenLimit 计数器与其他嵌入式工具共用。

查找并导入生成器模型

使用 /model-generator/models 列出可用的、附带生成器的模型。generator 描述符固定指定 projectId、revision、configurationId、templateRevision、productId 和 productModel3dId。按其 importPath 获取对应的确切源修订版本。商品资源清单也会提供 generators 以及各个模型的 generator 描述符。模板可按配置和修订版本单独导入。

目录筛选条件

项目导入包包含 document、revision、template 和 files 清单。每个文件都提供一个位于 /v1/model-generator/ 下的 path；从 Alter Product 下载时，在其前面加上 /public-api。将所需文件复制到自己的存储空间，并用本地引用替换源引用。通过各自的目录端点导入人体模型和纹理库；public-files 仅允许访问获准的资源路径，模板也必须通过相应配置和修订版本的访问权限检查。

请求示例（fetch）

// Server-side: uses the alterFetch helper and authHeaders defined above.
const catalog = await alterFetch('/model-generator/models?' + new URLSearchParams({
  scope: 'all', limit: '24', offset: '0'
}));

const selected = catalog.items[0];
if (!selected?.generator) throw new Error('Select an available generator model');

const importPath = selected.generator.importPath;
if (!importPath.startsWith('/v1/model-generator/projects/')) {
  throw new Error('Invalid generator import path');
}
const bundle = await alterFetch(importPath.slice('/v1'.length));

for (const file of bundle.files) {
  if (!file.path.startsWith('/v1/model-generator/')) {
    throw new Error('Invalid generator file path');
  }
  const response = await fetch('https://alterproduct.com/public-api' + file.path, {
    headers: authHeaders,
    redirect: 'error'
  });
  if (!response.ok) throw new Error(`File download failed: ${response.status}`);
  const bytes = new Uint8Array(await response.arrayBuffer());
  // Persist bytes in your local storage; record the mapping from
  // file.sourceHref / file.href to the resulting local file reference.
}
// Persist bundle.document, bundle.template and revision metadata locally.
// Import the related product asset and its textures/mockups as needed:
const product = await alterFetch('/assets/products/' + selected.generator.productId);
const mannequins = await alterFetch('/model-generator/mannequins');
console.log({ product, mannequins });

编辑器会话与本地存储

创建编辑器会话时，传入 tool: model-generator、标识本地生成器项目的正数 toolId（不是项目 UUID 或 WooCommerce 商品 ID），以及允许的店面 origin。此工具不应传入 designId、orderId、runtimeBindingId 或购物车字段。生成器项目的 UUID 是独立的标识符。通过 iframe 握手传递返回的 token；运行时初始化会返回包含 storageMode: wordpress_local 的生成器上下文。

// Server-side, after authorizing the merchant's access to this local project.
const localProjectId = 42; // Local generator project ID, not its UUID or WC product ID.
const session = await alterFetch('/embed/session', {
  method: 'POST',
  body: JSON.stringify({
    tool: 'model-generator',
    toolId: localProjectId,
    origin: 'https://yourstore.com'
  })
});

// The iframe receives session.token through ALTER_CUSTOMIZER_SESSION_READY.
// Do not put API credentials or the token in the iframe URL.
const bootstrapResponse = await fetch('https://alterproduct.com/public-api/v1/runtime/bootstrap', {
  headers: { Authorization: `Bearer ${session.token}` }
});
if (!bootstrapResponse.ok) throw new Error('Generator bootstrap failed');
const context = await bootstrapResponse.json();
console.log(context);

响应示例

{
  "runtimeBindingId": null,
  "designId": null,
  "productId": 42,
  "toolId": 42,
  "runtimeType": "model-generator",
  "storageMode": "wordpress_local",
  "parentOrigin": "https://yourstore.com"
}

// Host page: WordPress returns a numeric toolId and a UUID in id.
const url = new URL('https://alterproduct.com/app/model-generator');
url.search = new URLSearchParams({
  embedded: '1',
  lng: 'en',
  parentOrigin: window.location.origin,
  toolId: String(localProject.toolId),
  serverProjectId: localProject.id
}).toString();
// Optional: serverProjectRevision pins an existing saved revision.
iframe.src = url.toString();
// Install the authenticated handshake and storage bridge described below.
// Setting iframe.src alone does not authorize the editor or provide storage.

WordPress 桥接使用的 iframe 消息

WordPress 插件承载存储桥接功能，并检查管理员或 WooCommerce 店铺管理员权限。它会验证 iframe 的 origin、源窗口、nonce、请求 ID 以及允许的项目路径。桥接功能将本地读写请求发送到 /wp-json/alter-wc/v1/model-generator。API 凭据保留在服务器端。自定义集成必须实现同等的、经过身份验证的存储处理机制；公共生成器 API 不会将项目保存到 Alter Product。

// Messages after ALTER_CHILD_HELLO / ALTER_PARENT_ACK agree on the nonce.
// Iframe -> parent:
const sessionRequest = {
  type: 'ALTER_CUSTOMIZER_INIT_SESSION',
  nonce: handshakeNonce,
  payload: {
    tool: 'model-generator', alterProductId: localProject.toolId, mode: 'edit'
  }
};

// Parent -> iframe, after the server authorizes the merchant and issues a token:
const sessionReady = {
  type: 'ALTER_CUSTOMIZER_SESSION_READY',
  nonce: handshakeNonce,
  token: session.token,
  tool: 'model-generator',
  cartKey: `model-generator:${localProject.id}`,
  mode: 'edit',
  localSession: false,
  adminSession: true
};
// Send only to the validated iframe's exact origin and source window.
// An authorized token and successful bootstrap are still required.

保存时提供 expectedRevision、templateRevision、document 和产物引用。每次保存都会创建一个不可变的修订版本；如果 expectedRevision 已过期，则返回 HTTP 409。WordPress 将元数据存储在数据库中，将文件存储在 uploads 目录中。JSON 会经过精简，并且仅在压缩能够减小体积时使用 gzip 压缩。

// Example message from the iframe; savedSnapshot and artifact IDs come
// from the generator. The host checks origin/source/nonce/project permissions.
const message = {
  type: 'ALTER_MODEL_GENERATOR_REQUEST',
  requestId: crypto.randomUUID(),
  nonce: handshakeNonce,
  request: {
    method: 'POST',
    path: `/pattern-generator/projects/${projectUuid}/revisions`,
    data: {
      expectedRevision: loadedRevision,
      name: projectName,
      templateRevision,
      document: savedSnapshot,
      references: { artifactIds: savedArtifactIds }
    },
    responseType: 'json'
  }
};

“在设计中使用已保存的模型”会将完整的已保存修订版本发布到关联设计。之后，顾客可以通过现有的 Customizer、Configurator 或 Viewer 查看它，同时仍遵循常规的商品绑定和订阅检查。生成器编辑器仍仅供商家使用。订单关联会保留已保存的项目及其修订版本，因此后续编辑不会在无提示的情况下改变以往订单。

素材目录

素材目录提供产品源素材、背景、环境、图形库条目、设计模板和样机素材。列表端点返回精简的描述信息，详情端点包含文件清单。

请求示例（fetch）

const assets = await alterFetch('/assets?' + new URLSearchParams({
  type: 'products',

错误与请求频率限制

大多数控制器错误会标准化为 code 响应。身份验证中间件和请求频率限制器可能改为返回 error 响应。

// Controller error
{
  "code": "assetCatalog.invalidType"
}

// Auth middleware or rate limit
{
  "error": "Unauthorized"
}

{
  "error": "Too Many Requests"
}
