# Set up credentials

> Configure local credentials. The platform injects them when the job runs.

Copy the script from the **Local SDK setup** modal in Less. The top of the file sets credentials for local development:

```python theme={null}
# LOCAL ONLY — the os.environ block below is for running on your machine.
# When copying this script into Less, omit the os.environ section entirely.
# The platform sets LESS_API_URL, LESS_API_TOKEN, and LESS_ASSET_ID for you.

import os

os.environ["LESS_API_URL"] = "your-less-api-url"
os.environ["LESS_API_TOKEN"] = "your-script-api-token"
os.environ["LESS_ASSET_ID"] = "your-python-asset-id"

import less

less.reload_config()  # pick up env if less was already imported

# END LOCAL ONLY
```

Keep credentials out of the script you paste into Less. The platform injects `LESS_API_URL`, `LESS_API_TOKEN`, and `LESS_ASSET_ID` automatically when the job runs.

| Env              | Purpose                                               |
| ---------------- | ----------------------------------------------------- |
| `LESS_API_URL`   | e.g. `https://app.example.com/api`                    |
| `LESS_API_TOKEN` | script-api-token from the UI (expires after 24 hours) |
| `LESS_ASSET_ID`  | Python asset id                                       |
| `LESS_JOB_ID`    | set only on platform runs                             |
