If your team has access to an API key, you'll be able to use its several functionalities including creating new Projects and Time off types.
The following are the fields used in the Create project API call:
Name of the new Project or Time off type
Author's Slack member ID. *
In case it is a Time off type,
Any custom Ref ID you use for your Projects or Time off types.
The name of the Project's Client.
The name of the Project or Time off type's Type.
The number of Total estimated hours of your Project.
Your Project or Time off type's description.
* The Slack member ID is alpha-numeric in this format: XXXXXXXXXXX.
You can find it by clicking on the user picture on Slack, click on "View full profile", then on the "More" button, and finally "Copy member ID". You can also get these IDs directly from the API with the Get Users calls.
** Time off types with Data range enabled will allow users that log this type, to set a date until when this type will be active.
Project or Time off type was successfully created.
