All requests to the GanttPRO REST API require X-API-KEY HTTP header:
X-API-KEY: YOUR_TEAM_API_KEY_HERE
Example:
X-API-KEY: abc1234aacc640ba803908a9dd668cb2
Where can I get an API key?
You can create and manage your API Keys in the web interface.
You must be the owner of the GanttPRO team account to be able to generate API keys for your team.
Make sure to store your API keys somewhere secure and never share them publicly.
