# Logs

A great debugging resource is the ability to view your function logs. To do so, go to the left sidebar and select the **Logs** icon, as shown below, to view your function's execution history:

In the function logs, you can confirm that data was successfully posted to Ubidots with the **201** response code:

This is what your function returns. It must be in JSON dictionary format. In your code, make sure to use **return** to exit the function and return the dictionary.

{% tabs %}
{% tab title="NodeJS" %}

```javascript
return response.data;
```

{% endtab %}

{% tab title="Python" %}

```python
return {"status": "Ok", "result": req.json()}
```

{% endtab %}
{% endtabs %}

You can also use logs for debugging. Print any variables defined earlier, or print any message that needs to be displayed to the user.

```javascript
console.log("[INFO] Request result:");
console.log(response);
```

{% endtab %}

{% tab title="Python" %}

```python
print("[INFO] Request result:")
print(req.text)
```

{% endtab %}
{% endtabs %}
