@gauchy Well, it didn't work with 'select', I had to change it to 'status' for the script to work. What led me to the answer was the structure of the json files created by the script.

EDIT: I would be so glad if you managed to make two-way syncing! For me the best way would be to change the name of the new task to sync on both databases, adding your current N2H_ prefix. Then, if you detect one of the two is missing (either by keeping track of the tasks in a json or simply by checking if there is a lonely N2H_ task), you would ✅ the task on both DB.
I have no experience with web services yet, but I'm eager to learn so if you need any help with this little project just ask me :)

@elliotfontaine - did a few changes for two way sync, have a look if it works.
Why status is working for you instead of select is perhaps because the property type you have chosen is of 'status' type not 'select'. See here - https://developers.notion.com/reference/property-object

The following is machine translation, English is not my native language.

Great project 👍
two way sync is work, but if the task name is duplicated, there will be problems.

I made some small modifications 62 - 190

• Notion create new property "HabiticaID" type "text" => Two-way sync key
• syncNotionToHabitica function check "habitica.json" and "habitica_done.json" for absences

Hi there, I updated some steps of the tutorial like adding the integration and add few code inside like the difficulty of the task in Habitica depends on the priority in Notion or removing the prefix.

My bad I forgot to make a fork of your work
