    },
    async ({ channelId, name, description, type, applicationId }) => {
      try {
        const data = {
          name,

  );

• src/index.ts:22-52 (helper)

  Shared helper function makeApiRequest used by marketo_update_channel (and other tools) to make authenticated API calls to Marketo.

  async function makeApiRequest(
    endpoint: string,
    method: string,
    data?: any,
    contentType: string = 'application/json'
  ) {
    const token = await tokenManager.getToken();
    const headers: any = {
      Authorization: `Bearer ${token}`,
    };
  
    if (contentType) {
      headers['Content-Type'] = contentType;
    }
  
    try {
      const response = await axios({
        url: `${MARKETO_BASE_URL}${endpoint}`,
        method: method,
        data:
          contentType === 'application/x-www-form-urlencoded'
            ? new URLSearchParams(data).toString()
            : data,
        headers,
      });
      return response.data;
    } catch (error: any) {
      console.error('API request failed:', error.response?.data || error.message);
      throw error;
