  }

  async request(path, { method = "GET", body } = {}) {
    const response = await fetch(`${this.baseUrl}${path}`, {
      method,
      headers: {
        Authorization: `Bearer ${this.apiKey}`,
        ...(body ? { "Content-Type": "application/json" } : {}),
      },
      body: body ? JSON.stringify(body) : undefined,
    });

    if (!response.ok) {
      throw new Error(`PostShiba ${method} ${path}: ${response.status} ${await response.text()}`);
    }

    if (response.status === 204) return null;
    return response.json();
  }

  async provisionCustomer({ name, slug, domain }) {
    const tenant = await this.request(
      `/api/v1/teams/${this.teamId}/tenants`,
      {
        method: "POST",
