In fact, the endpoint “/device/:deviceID/data“ not working at all.

Is this a bug?

Hey @julihermes.melo! We already reached out through your support ticket, but wanted to share the answer here too in case anyone else runs into this.

In this case, you’ll need to use an **Analysis Token**.

Here’s a quick example:

```auto
curl --location 'https://api.us-e1.tago.io/device/{deviceID}/data' \
--header 'token: YOUR_ANALYSIS_TOKEN' \
--header 'Content-Type: application/json' \
--data '[
  {
    "variable": "example",
    "value": "1"
  }
]'

```

Just make sure your Analysis has access to the device through the **Access Management** module.

Let us know if you have any questions! 🙌
