# Incremental Authorizations

You may wish to configure your PayForm to collect an Initial *Authorization Only*.

This Authorization can be Reversed or Incrementally increased during your workflow and eventually finalized and sent for settlement.  In order to Specify *Authorization Only* adjust your [request](/api-reference/rest-api/payform.md) as follows

{% code overflow="wrap" %}

```jsonc
"eFeatures": "0008",
```

{% endcode %}

This tells the PayForm that any dollar amount authorized will stay in a PENDING state awaiting any changes or Incremental increases you specify using our API.

{% hint style="warning" %}
Be VERY CAREFUL when setting this feature value; transactions collected here will rely on you to FINALIZE them using the API. If you do an Authorization Only for a dollar value, the merchant WILL NOT collect the funds until you FINALIZE the transaction.
{% endhint %}

Use this REST API call to execute incremental authorizations or finalize the transaction:

{% content-ref url="/pages/mIUOkLIdbQGmBaUi7xmi" %}
[Incremental Auth](/api-reference/rest-api/card-operations/authentication.md)
{% endcontent-ref %}

## 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.number.tech/documentation/getting-started/integration-options/payform/incremental-authorizations.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.
