# Configuring Your Payload

## Metafield Namespaces

By default, Shopify trigger data excludes metafield information. Use MESA’s Metafield Namespaces feature to add metafield data to your workflow’s trigger data.

For example, to include global metafields, you will need to include the "global" namespace.

## Limit Trigger Payload at Execution

This feature lets you reduce the data included in the trigger payload. Selecting fields from the dropdown limits the payload to only those values from Shopify. This helps minimize unnecessary activity and optimize queries for efficiency. To filter for specific data, use a [Filter](/tools/filter.md) step after the trigger step instead.

Using the Limit Trigger Payload at Execution feature won’t limit what you see in MESA’s Testing and Variables features. All data and variables will still appear.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.getmesa.com/connect/shopify/technical-notes/configuring-your-payload.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
