API /api/permissions?type=device Not Available (405/404) on Official Traccar 6.7.3 – How to Retrieve User-Device Links?

Zero19 days ago

Hello Traccar community,
I am running the official Traccar 6.7.3 (downloaded from traccar.org) on a clean Ubuntu server with an admin user and a fresh database.
I am developing a plugin that needs to retrieve the mapping between users and devices via the API.
What works:
I can successfully call /api/users and /api/devices (status 200, correct data).
I can log in with an admin token and see all users and devices.
What does NOT work:
When I call /api/permissions?type=device (with GET and admin token), I get:
405 Method Not Allowed or sometimes 404 Not Found
When I call /api/users/{id}/devices, I get:
404 Not Found
The endpoint /api/permissions?type=device does not appear in /api/openapi.html either.
What I have tried:
Clean install of Ubuntu and Traccar 6.7.3 (official ZIP, not a package or custom build)
Using a verified admin token
No firewall or reverse proxy blocking
Devices are linked to users in the Traccar web interface and visible in the database (tc_user_device table)
Checked logs for errors (none found)
Tested on multiple servers and environments
My question:
Why is the /api/permissions?type=device endpoint not available or returning 405/404, even on a clean official install with an admin token?
How can I retrieve the user-device mapping via the API, as recommended in the documentation for Traccar 5.x and above?
Any help or suggestions would be greatly appreciated!
If you need more logs or details, let me know.
Thank you!

Where did you get /api/permissions?type=device from?

Hi Anton tanx for the reply
The API Reference describes a GET /api/permissions endpoint, with a type query parameter (e.g., type=device) to filter permission types.
Example from the docs: GET /api/permissions?type=device

Since Traccar 5.x, the permissions model was unified, and /api/permissions became the recommended way to get all user-device, user-group, and other permission links.
If this is not correct, or if the endpoint has changed, I would really appreciate clarification on the official way to retrieve all user-device links via the API in Traccar 6.x.
Thank you for your help!

The API Reference describes a GET /api/permissions endpoint, with a type query parameter

Please provide a link. I don't see anything like that in the API reference.

Thank you for your quick response.
I referred to the Traccar API Reference here:
https://www.traccar.org/api-reference/#operation/getPermissions
This page documents the GET /api/permissions endpoint.
It shows several query parameters, including type, which can be used to filter the permissions by type (such as device, group, etc.).
Direct quote from the documentation:

GET /api/permissions

Query parameters:

  • type (string) – Permission type (e.g. device, group, etc.)
  • userId (long) – User identifier
  • deviceId (long) – Device identifier
  • groupId (long) – Group identifier

if this is not the intended usage, I would appreciate your guidance on the correct way to retrieve all user-device links via the API in Traccar 6.x.
Thank you!

Please provide a screenshot.

I have seen /api/permissions?type=device referenced in forum posts and migration guides for Traccar 5.x and above, and I assumed it was the official way to retrieve user-device links. However, I now realize that the current API Reference at https://www.traccar.org/api-reference/ does not explicitly document this usage or provide an example with type=device.

I would appreciate your guidance on the correct way to retrieve all user-device links via the API in Traccar 6.x.
Thank you!

i know it's not nice that i let AI help me with my post i will check everything from now on and use google translate for translating here my english is not so good sorry for my behavior.

i don't know if i can still ask the question but is it possible to retrieve via the api user linked to the divece? otherwise this could be done via the database but this is less nice and safe i think

Anton Tananaev18 days ago

It's not possible to retrieve all links. You can only get devices by user id.
