<p>The <strong>Data Operations</strong> component performs operations on <a class="" href="/data-types#data"><code>Data</code></a> objects, including extracting, filtering, and editing keys and values in the <code>Data</code>.
|
||
For all options, see <a href="#available-data-operations" class="">Available data operations</a>.
|
||
The output is a new <code>Data</code> object containing the modified data after running the selected operation.</p>

|
||
<p>The following example demonstrates how to use a <strong>Data Operations</strong> component in a flow using data from a webhook payload:</p>
|
||
<ol>
|
||
<li class="">
|
||
<p>Create a flow with a <strong>Webhook</strong> component and a <strong>Data Operations</strong> component, and then connect the <strong>Webhook</strong> component's output to the <strong>Data Operations</strong> component's <strong>Data</strong> input.</p>
|
||
<p>All operations in the <strong>Data Operations</strong> component require at least one <code>Data</code> input from another component.
|
||
If the preceding component doesn't produce <code>Data</code> output, you can use another component, such as the <a class="" href="/type-convert"><strong>Type Convert</strong> component</a>, to reformat the data before passing it to the <strong>Data Operations</strong> component.
|
||
Alternatively, you could consider using a component that is designed to process the original data type, such as the <a class="" href="/parser"><strong>Parser</strong> component</a> or <a class="" href="/dataframe-operations"><strong>DataFrame Operations</strong> component</a>.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>In the <strong>Operations</strong> field, select the operation you want to perform on the incoming <code>Data</code>.
|
||
For this example, select the <strong>Select Keys</strong> operation.</p>

|
||
If you need to perform multiple operations on the data, you can chain multiple <strong>Data Operations</strong> components together to execute each operation in sequence.
|
||
For more complex multi-step operations, consider using a component like the <a class="" href="/smart-transform"><strong>Smart Transform</strong> component</a>.</p></div></div>
|
||
</li>
|
||
<li class="">
|
||
<p>Under <strong>Select Keys</strong>, add keys for <code>name</code>, <code>username</code>, and <code>email</code>.
|
||
Click <svg xmlns="http://www.w3.org/2000/svg" width="24" height="24" viewBox="0 0 24 24" fill="none" stroke="currentColor" stroke-width="2" stroke-linecap="round" stroke-linejoin="round" class="lucide lucide-plus" aria-hidden="true"><path d="M5 12h14"></path><path d="M12 5v14"></path></svg> <strong>Add more</strong> to add a field for each key.</p>
|
||
<p>For this example, assume that the webhook will receive consistent payloads that always contain <code>name</code>, <code>username</code>, and <code>email</code> keys.
|
||
The <strong>Select Keys</strong> operation extracts the value of these keys from each incoming payload.</p>
|
||
</li>
|
||
<li class="">
|
||
<p>Optional: If you want to view the output in the <strong>Playground</strong>, connect the <strong>Data Operations</strong> component's output to a <strong>Chat Output</strong> component.</p>

|

</li>
|
||
<li class="">

||
<p>To test the flow, send the following request to your flow's webhook endpoint.
