Bad request - please check your parameters [item 0] 400 Bad Request Error: Bad Request Your client has issued a malformed or illegal request. I’m using n8n, calling the API with HTTP request node. I tried the community note with n8n integrated token authentication and API [https://api.track.toggl.com/api/v9/me/time\_entries](https://api.track.toggl.com/api/v9/me/time_entries) It worked Then I tried in the same way the HTTP Request note to call the same API, it worked putting start\_date and end\_date in the header. ![image](https://canada1.discourse-cdn.com/flex012/uploads/toggl1/original/2X/5/54949620a91fc606949aecbd5f5fd96550e1fcaf.png) This told me that the way n8n authenticates with Toggl Track API is OK. I’m also sure the time formatting is OK. The detailed report API [https://api.track.toggl.com/reports/api/v3/workspace/{workspace\_id}/search/time\_entries](https://api.track.toggl.com/reports/api/v3/workspace/%7Bworkspace_id%7D/search/time_entries) gives error 400 putting start\_date and end\_date in the body. gives erro 405 putting start\_date and end\_date in the header.
