# Upload Tracking Inputs

> Upload tracking angle configuration for a shading scene

# POST /shadingscenes/{scene_id}/trackinginputs

Save single-axis tracker parameters and link them to the specified shading scene. These parameters control backtracking behavior and terrain-aware tracking adjustments used during shading simulation.

## Notes

* Content type is `application/x-www-form-urlencoded`.
* `gcr` (Ground Coverage Ratio) is the only required field. All other parameters have sensible defaults.
* Default parameter values:
  * `azimuth`: `0.0`
  * `axis_tilt`: `0.0`
  * `back_tracking`: `true`
  * `max_angle`: `60.0`
  * `terrain_aware`: `false`
* `terrain_aware_diode_threshold` and `terrain_aware_method` are only relevant when `terrain_aware` is `true`.
* On success, returns the new `trackingInputId` and the associated `shadingSceneId`.
* Returns `404` if the scene does not exist in the current workspace.
* Requires write-level workspace access.
* After uploading new tracking inputs, use [POST /shadingscenes/{scene_id}/refresh](/api-reference/endpoints/shading-scenes-refresh) to re-run shading with the updated tracker configuration.
