FRED Economic Series IDs
<p>I am trying to use the FRED API to get the economic data. The examples provided on the FRED website uses series Id to get the observations/values for a particular series. I am not able to find where I can find the series IDs. For example, in the below example it is asking for series id to get the data-</p>

<pre><code>https://api.stlouisfed.org/fred/series/observations?series_id=GNPCA&amp;api_key=*your_key*
</code></pre>

<p>Any help is appreciated.</p>
