Sharing (and Un-Sharing) Notes
How to start and stop sharing a single note, as well as how to retrieve a list all of the shared notes in an Evernote account.

Single Note Sharing
Single notes can be shared in one of two ways: publicly (using a public note URL) or via email. The latter isn’t exactly sharing as much as it is emailing a copy of a note, so we’re going to focus on the former: sharing via a public shared URL. Note that there isn’t a way to share a single note with only one other person; anybody who knows the URL for a shared note will be able to view it.
In order to share a single note, you’ll need the following information:
- The GUID of the note you’d like to share.
- The ID of the Shard that houses the note to be shared.
- A valid authentication token or developer token.
- Initialized instances of
NoteStore.ClientandUserStore.Client
The Shard ID can be determined at runtime by querying the UserStore:
main.py def getUserShardId(authToken, userStore): """ Get the User from userStore and return the user's shard ID """ try: user = userStore.getUser(authToken) except (Errors.EDAMUserException, Errors.EDAMSystemException), e: print "Exception while getting user's shardID:" print type(e), e return None if hasattr(user, 'shardId'): return user.shardId return Nonegistfile1.m - (void)getUserShardId { //Get the User from userStore and return the user's shard ID [[EvernoteUserStore userStore] getUserWithSuccess:^(EDAMUser *user) { NSString* shardId = user.shardId; NSLog(@"Shard id : %@",shardId); } failure:^(NSError *error) { NSLog(@"Error : %@",error); }]; }example.rb def get_user_shard_id(user_store) # Get the User from userStore and return the user's shard ID begin user = user_store.getUser return user.shardId rescue Evernote::EDAM::Error::EDAMUserException, Evernote::EDAM::Error::EDAMSystemException => e puts "Exception while getting user's shardID:" puts e.inspect end endexample.php <?php function getUserShardId($userStore) { // Get the User from userStore and return the user's shard ID try { $user = $userStore->getUser(); return $user->shardId; } catch (EDAMUserException $e) { print "Exception while getting user's shardID:"; print var_dump($e); } catch (EDAMSystemException $e) { print "Exception while getting user's shardID:"; print var_dump($e); } return null; } ?>example.java public String getUserShardId(UserStoreClient userStore) { // Get the User from userStore and return the user's shard ID try { user = userStore.getUser(); return user.getShardId(); } catch (EDAMUserException e) { System.out.println("Exception while getting user's shardID:"); System.out.println(e); } catch (EDAMSystemException e) { System.out.println("Exception while getting user's shardID:"); System.out.println(e); } catch (TException e) { System.out.println("Exception while getting user's shardID:"); System.out.println(e); } return null; }example.js function getUserShardId(userStore, callback) { // Get the User from userStore and return the user's shard ID userStore.getUser(function(user) { if (user.errorCode) { console.log("Exception while getting user's shardID:"); console.log(user); } else { callback(user.shardId); } }); }Assuming all of that is in place, sharing a note is actually quite simple. By calling
NoteStore.shareNoteand passing a valid authentication token and the GUID of the note you’d like to share. In return, you’ll get a Share Key from the Evernote Cloud API that can be used in conjunction with the note GUID to view a read-only version of the note.Here’s a snippet of code that illustrates how the whole process works:
main.py def shareSingleNote(authToken, noteStore, userStore, noteGuid, shardId=None): """ Share a single note and return the public URL for the note """ if not shardId: shardId = getUserShardId(authToken, userStore) if not shardId: raise SystemExit try: shareKey = noteStore.shareNote(authToken, noteGuid) except (EDAMNotFoundException, EDAMSystemException, EDAMUserException), e: print "Error sharing note:" print type(e), e return None return "%s/shard/%s/sh/%s/%s" % \ (EN_URL, shardId, noteGuid, shareKey)gistfile1.m - (void)shareSingleNoteWithNoteGUID:(NSString*)noteGUID withShardId:(NSString*)shardId { // Share a single note and return the public URL for the note [[EvernoteNoteStore noteStore] shareNoteWithGuid:noteGUID success:^(NSString *noteKey) { NSString* shareURL = [NSString stringWithFormat:@"%@/shard/%@/sh/%@/%@",[[EvernoteSession sharedSession] host] ,shardId,noteGUID, noteKey]; NSLog(@"Share URL : %@",shareURL); } failure:^(NSError *error) { NSLog(@"Error : %@",error); }]; }example.rb def share_single_note(note_store, user_store, note_guid, shard_id=nil) # Share a single note and return the public URL for the note shard_id ||= get_user_shard_id(user_store) raise "Couldn't get shard_id" unless shard_id begin share_key = note_store.shareNote(note_guid) return "#{EN_URL}/shard/#{shard_id}/sh/#{note_guid}/#{share_key}" rescue Evernote::EDAM::Error::EDAMNotFoundException, Evernote::EDAM::Error::EDAMSystemException, Evernote::EDAM::Error::EDAMUserException => e puts "Error sharing note:" puts e.inspect end endexample.php <?php function shareSingleNote($noteStore, $userStore, $noteGuid, $shardId = null) { // Share a single note and return the public URL for the note if (!isset($shardId)) { $shardId = getUserShardId($userStore); if (!isset($shardId)) { throw new Exception(); } } try { $shareKey = $noteStore->shareNote($noteGuid); return EN_URL . "/shard/" . $shardId . "/sh/" . $noteGuid . "/" . $shareKey; } catch (EDAMNotFoundException $e) { print "Error sharing note:"; print var_dump(e); } catch (EDAMSystemException $e) { print "Error sharing note:"; print var_dump(e); } catch (EDAMUserExceptipon $e) { print "Error sharing note:"; print var_dump(e); } return null; } ?>example.java public String shareSingleNote(NoteStoreClient noteStore, UserStoreClient userStore, String noteGuid, String shardId) { // Share a single note and return the public URL for the note if (shardId == null) { shardId = getUserShardId(userStore); } try { String shareKey = noteStore.shareNote(noteGuid); return EN_URL + "/shard/" + shardId + "/sh/" + noteGuid + "/" + shareKey; } catch (EDAMNotFoundException e) { System.out.println("Error sharing note:"); System.out.println(e); } catch (EDAMSystemException e) { System.out.println("Error sharing note:"); System.out.println(e); } catch (EDAMUserException e) { System.out.println("Error sharing note:"); System.out.println(e); } catch (TException e) { System.out.println("Error sharing note:"); System.out.println(e); } return null; }example.js function shareSingleNote(noteStore, userStore, noteGuid, shardId, callback) { // Share a single note and return the public URL for the note noteStore.shareNote(noteGuid, function(shareKey) { if (shareKey.errorCode) { console.log("Error sharing note:"); console.log(shareKey); } else { callback(EN_URL + "/shard/" + shardId + "/sh/" + noteGuid + "/" + shareKey); } }); }Assuming nothing broke, the above function will return a public note URL that looks something like this:
https://www.evernote.com/shard/s1/sh/36dd7123-12c0-457a-a6d0-75555fcc7770/3afc29de3493d0d333b54cf1822be92cThe last two pieces of data in the URL are the note GUID and the share key.

Stop Sharing a Note
This is about as close to a one-liner as you can get.
You’ll need an initialized
NoteStore.Clientinstance, a good authentication token and the GUID of the note in question. With those things in place, it’s as simple as callingNoteStore.stopSharingNote:main.py def stopSharingSingleNote(authToken, noteStore, noteGuid): try: noteStore.stopSharingNote(authToken, noteGuid) except (EDAMNotFoundException, EDAMSystemException, EDAMUserException), e: print "Error stopping sharing note:" print type(e), e return None return noteGuidgistfile1.m - (void)stopSharingSingleNoteWithNoteGUID:(NSString*)noteGUID { // Share a single note and return the public URL for the note [[EvernoteNoteStore noteStore] stopSharingNoteWithGuid:noteGUID success:^{ NSLog(@"Stopped sharing note"); } failure:^(NSError *error) { NSLog(@"Error : %@",error); }]; }example.rb def stop_sharing_single_note(note_store, note_guid) begin note_store.stopSharingNote(note_guid) return note_guid rescue Evernote::EDAM::Error::EDAMNotFoundException, Evernote::EDAM::Error::EDAMSystemException, Evernote::EDAM::Error::EDAMUserException => e puts "Error stopping sharing note:" puts e.inspect end endexample.php <?php function stopSharingSingleNote($noteStore, $noteGuid) { try { $noteStore->stopSharingNote($noteGuid); return $noteGuid; } catch (EDAMNotFoundException $e) { print "Error stopping sharing note:"; print var_dump($e); } catch (EDAMSystemException $e) { print "Error stopping sharing note:"; print var_dump($e); } catch (EDAMUserException $e) { print "Error stopping sharing note:"; print var_dump($e); } return null; } ?>example.java public String stopSharingSingleNote(NoteStoreClient noteStore, String noteGuid) { try { noteStore.stopSharingNote(noteGuid); return noteGuid; } catch (EDAMNotFoundException e) { System.out.println("Error stopping sharing note:"); System.out.println(e); } catch (EDAMSystemException e) { System.out.println("Error stopping sharing note:"); System.out.println(e); } catch (EDAMUserException e) { System.out.println("Error stopping sharing note:"); System.out.println(e); } catch (TException e) { System.out.println("Error stopping sharing note:"); System.out.println(e); } return null; }example.js function stopSharingSingleNote(noteStore, noteGuid, callback) { noteStore.stopSharingNote(noteGuid, function(obj) { if (obj && obj.errorCode) { console.log(obj); } else { callback(noteGuid); } }); } -
Listing All Shared Notes in an Account
To search for all of the shared notes in a user’s account, we need to create a
NoteFilterobject and set itswordsmember tosharedate:*(indicating that the note is shared and we don’t care when). Here’s a function that retrieves all of the shared notes in a user’s account (up to an arbitrary maximum of 500 notes):main.py def getAllSharedNotes(authToken, noteStore, maxCount=None): noteFilter = NoteStore.NoteFilter() noteFilter.words = "sharedate:*" sharedNotes = [] offset = 0 if not maxCount: maxCount = 500 while len(sharedNotes) < maxCount: try: noteList = noteStore.findNotes(authToken, noteFilter, offset, 50) sharedNotes += noteList.notes except (EDAMNotFoundException, EDAMSystemException, EDAMUserException), e: print "Error getting shared notes:" print type(e), e return None if len(sharedNotes) % 50 != 0: ## We've retrieved all of the notes break else: offset += 50 return sharedNotes[:maxCount]gistfile1.m - (void) getAllSharedNotes { EDAMNoteFilter *noteFilter = [[EDAMNoteFilter alloc] initWithOrder:0 ascending:YES words:@"sharedate:*" notebookGuid:nil tagGuids:nil timeZone:nil inactive:NO emphasized:nil]; EDAMNotesMetadataResultSpec* metaDataResultSpec = [[EDAMNotesMetadataResultSpec alloc] initWithIncludeTitle:YES includeContentLength:YES includeCreated:NO includeUpdated:NO includeDeleted:NO includeUpdateSequenceNum:NO includeNotebookGuid:YES includeTagGuids:YES includeAttributes:YES includeLargestResourceMime:NO includeLargestResourceSize:NO]; __block NSInteger i = 0; __block NSInteger totalNoteCount = 0; do { [[EvernoteNoteStore noteStore] findNotesMetadataWithFilter:noteFilter offset:i maxNotes:10 resultSpec:metaDataResultSpec success:^(EDAMNotesMetadataList *metadata) { NSLog(@"Shared notes metadata : %@",metadata); i += metadata.notes.count; totalNoteCount = metadata.totalNotes; } failure:^(NSError *error) { NSLog(@"Error : %@",error); }]; } while (i<totalNoteCount); }example.rb def get_all_shared_notes(note_store, max_count=nil) note_filter = Evernote::EDAM::NoteStore::NoteFilter.new note_filter.words = "sharedate:*" shared_notes = [] offset = 0 max_count ||= 500 while shared_notes.length < max_count begin note_list = note_store.findNotes(note_filter, offset, 50) shared_notes += note_list.notes rescue Evernote::EDAM::Error::EDAMNotFoundException, Evernote::EDAM::Error::EDAMSystemException, Evernote::EDAM::Error::EDAMUserException => e puts "Error getting shared notes:" puts e.inspect return nil end if shared_notes.length % 50 != 0 ## We've retrieved all of the notes break else offset += 50 end end shared_notes[0..max_count-1] endexample.php <?php function getAllSharedNotes($noteStore, $maxCount = null) { $noteFilter = new NoteFilter(); $noteFilter->words = "sharedate:*"; $sharedNotes = array(); $offset = 0; if ($maxCount == null) { $maxCount = 500; } while (count($sharedNotes) < $maxCount) { try { $noteList = $noteStore->findNotes($noteFilter, $offset, 50); $sharedNotes += $noteList->notes; } catch (EDAMNotFoundException $e) { print "Error getting shared notes:"; var_dump($e); return null; } catch (EDAMSystemException $e) { print "Error getting shared notes:"; var_dump($e); return null; } catch (EDAMUserException $e) { print "Error getting shared notes:"; var_dump($e); return null; } if (count($sharedNotes) % 50 != 0) { // We've retrieved all of the notes break; } else { $offset += 50; } } return array_slice($sharedNotes, 0, $maxCount); } ?>example.java public List<Note> getAllSharedNotes(NoteStoreClient noteStore, int maxCount) { NoteFilter noteFilter = new NoteFilter(); noteFilter.setWords("sharedate:*"); List<Note> sharedNotes = new ArrayList<Note>(); int offset = 0; while (sharedNotes.size() < maxCount) { try { NoteList noteList = noteStore.findNotes(noteFilter, offset, 50); sharedNotes.addAll(noteList.getNotes()); } catch (EDAMNotFoundException e) { System.out.println("Error getting shared notes:"); System.out.println(e); return null; } catch (EDAMSystemException e) { System.out.println("Error getting shared notes:"); System.out.println(e); return null; } catch (EDAMUserException e) { System.out.println("Error getting shared notes:"); System.out.println(e); return null; } catch (TException e) { System.out.println("Error getting shared notes:"); System.out.println(e); return null; } if (sharedNotes.size() % 50 != 0) { // We've retrieved all of the notes break; } else { offset += 50; } } return sharedNotes.subList(0, Math.min(sharedNotes.size(), maxCount)); }example.js function getAllSharedNotes(noteStore, maxCount, callback) { var noteFilter = new Evernote.NoteFilter(); noteFilter.words = "sharedate:*"; var sharedNotes = []; var offset = 0; if (!maxCount) { maxCount = 500; } (function _getAllSharedNotes(sharedNotes, offset, maxCount) { if (sharedNotes.length < maxCount) { noteStore.findNotes(noteFilter, offset, 50, function(noteList) { if (noteList.errorCode) { console.log("Error getting shared notes:"); console.log(noteList); return; } sharedNotes = sharedNotes.concat(noteList.notes); if (sharedNotes.length % 50 != 0) { // We've retrieved all of the notes callback(sharedNotes.slice(0, maxCount)); return; } else { offset += 50; _getAllSharedNotes(sharedNotes, offset, maxCount); } }); } else { callback(sharedNotes.slice(0, maxCount)); } })(sharedNotes, offset, maxCount); }After creating and populating our
NoteFilterinstance, we repeatedly callNoteStore.findNotes, asking for 50 notes each time, collecting the responses into asharedNotescollection. Once we hit our maximum number of notes or oursharedNotescollection is no longer evenly divisible by 50 (indicating that we received less than 50 notes during the most recent call toNoteStore.findNotes), we returnsharedNotes.
