You can provide either All, One or None of the parameters for enableGooglePay call.

* `amountField` specified - in this case Google Pay total amount will be automatically updated whenever amount has changed
* `amountField` *is not* specified - in this case it’s up to you to provide the correct amount for Google Pay. One of the ways to do it is to call `window.ckGooglePay.updateAmount` manually.
* `iframeField` specified - this value will be used to communicate with Google Pay button.\
  This option is especially helpful for Angular clients using shadow DOM.
* `iframeField` *is not* specified - it’s value will be calculated based on `data-ifields-id` attribute. In this case it must be set to “igp“: `data-ifields-id="igp"`.

## 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.solapayments.com/mobile-wallets/google-pay-hosted-checkout/google-pay-control-object.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.
