How to list all JPG images in a Dropbox directory using Zapier

Hi ​@pabloferre 

This might not be possible with the standard Dropbox actions, but it’s definitely doable with a custom action. Try creating one using the code below, then save and publish it. After that, you should be able to pick it from the Custom Action tab when you select the Dropbox app in an action step.

// Define an async function to list all .jpg files in a specified Dropbox directory
export async function listJpgFilesInDirectory(params: { path: string }): Promise<{ result: string[] }> {
  // Extract the path from the input object
  const { path } = params;

  // Define the API endpoint URL
  const url = 'https://api.dropboxapi.com/2/files/list_folder';

  // Prepare the request body with the required path and optional parameters
  // If the path is "/", replace it with an empty string to specify the root folder
  const requestBody = {
    path: path === '/' ? '' : path, // Correctly handle the root folder case
    recursive: false, // Not recursive, only list the specified folder
    include_deleted: false, // Do not include deleted files
    include_media_info: false, // Do not include media info
    include_mounted_folders: true, // Include mounted folders
    include_non_downloadable_files: false, // Do not include non-downloadable files
    include_has_explicit_shared_members: false // Do not include explicit shared members info
  };

  // Make the API request using fetchWithZapier
  const response = await fetchWithZapier(url, {
    method: 'POST',
    headers: {
      'Content-Type': 'application/json'
    },
    body: JSON.stringify(requestBody)
  });

  // Throw an error if the response is not ok
  await response.throwErrorIfNotOk();

  // Parse the JSON response
  const data = await response.json();

  // Filter the entries to only include files with a .jpg extension
  const jpgFiles = data.entries
    .filter((entry: { name: string }) => entry.name.toLowerCase().endsWith('.jpg'))
    .map((entry: { name: string }) => entry.name);

  // Return the list of .jpg files
  return { result: jpgFiles };
}

Hey ​@pabloferre,

Try using List Folder Contents action.
 

After that you can use a Loop and Filter to get just the JPG’s. Hope it helps!
