### Request Configuration

The `RequestConfig` object allows you to set request configuration option properties:

Key

Value

`retnb`

`[bool]` Return Non-Billable Taxes  

Flag indicating if non-billable taxes should be returned. Defaults to the account-level setting if not provided.

-   `true`: Return non-billable taxes. Setting `retnb` to `true` overrides the account-level setting
-   `false`: Don't return non-billable taxes

`retext`

`[bool]` Return Extended Data  

Flag indicating if extended tax information should be returned in the response.

-   `true`: Return the extended tax information
-   `false`: Don't return extended tax information

Forces Return Detail (`dtl`) to `true` on the [invoice](/communications/dev-guide_rest_v2/reference/invoice/). The return list resulting from this configuration option may change over time as additional data elements are added.  

`incrf`

`[bool]` Return Reporting Information  

Flag indicating if reporting information should be returned in the [response](/communications/dev-guide_rest_v2/reference/calc-taxes-response/).

-   `true`: Return the reporting information
-   `false`: Don't return the reporting information

The return list resulting from this configuration option may change over time as additional data elements are added.
