# Update Contact Fields

This card can be used to Update the Contact fields that you ask from your customers like their name, contact number, email, their availability, or any instruction they have given.

After choosing the field that you would like to update and the value for the field, you have to select the operation in some cases:

-> Choose **Replace**, if you want to update the previous contact details with new details.

-> Choose **Add if Empty**, to add the contact details to a particular contact.

-> Choose **Append**, if you want to add more to the details.

You can see the updated contact fields in the **Contact** section of Gallabox.

To change the Marketing Opt-ins, follow the below GIF:

## 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.whatstool.business/bots/bot-actions/update-contact-fields.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.
