# Find your Client ID, table IDs, and field IDs

Formulas, batch arguments, and settings for Quickbase Extensions refer to your account, tables, and fields by ID rather than by name. This article shows where to find your **Client ID**, a **table ID** (also called a DBID), a **table alias**, and a **field ID** (also called a FID).

You often don't need to look anything up. The buttons and fields the [installation wizard](https://help.quickbase.com/quickbase-extensions/docs/en/juiced-add-on-installation-wizard-overview) creates already contain the right IDs. Use this article when you change one of those formulas or build your own.

## Client ID

Your Client ID identifies your company's Quickbase Extensions account. It's the letter *Q* followed by a number, for example *Q1234*.

The installation wizard writes your Client ID into every button and batch arguments field it creates, usually as *clientid=Q…*. A few buttons use a different parameter name for the same value; for example, the XL Docs Configurator buttons use *qspclientid=Q…*.

To find your Client ID:

1. Open a table that has a button the installation wizard created.
2. Select **Settings** from the table card in the page bar, then select **Fields**.
3. Open the button field and look at its formula.
4. Copy the *Q…* value that follows *clientid=*.

The same formula also starts with your extension's server URL, created by the installation wizard. Keep that address unchanged when you edit the formula.

## Table ID (DBID)

A table ID identifies one table in Quickbase. Parameters that take a table usually end in *dbid*, such as *dbid=*.

- **From the address bar**—open the table and look at its address in the browser. The table ID is the part after *table/*, for example *.../nav/app/bxxxxxxxx/table/bxxxxxxxx/...*. In older addresses, it's the part after *db/*. See [URL changes in new navigation](https://help.quickbase.com/docs/url-changes-in-new-navigation).
- **In a formula on the same table**—use *Dbid()* instead of typing the ID.
- **In a formula that refers to another table**—use the table's alias. See [Table alias](https://help.quickbase.com/quickbase-extensions/docs/en/find-client-id-table-ids-field-ids#table-alias).

The app ID is the part of the address after *app/*. In a formula, use *AppID()* instead of typing it.

## Table alias ([_DBID_…])

A table alias is a name Quickbase gives each table for use in formulas. It starts with *_DBID_* and continues with the table name in capital letters, for example *_DBID_LINE_ITEMS*. In a formula, write it in square brackets, like a field: *[_DBID_LINE_ITEMS]*. Quickbase replaces it with the table's ID. The installation wizard uses table aliases in the formulas it creates.

To find a table's alias:

1. Open the table and select **Settings** from the table card in the page bar.
2. Select **Advanced settings**. The table alias appears in capital letters at the end of the **Advanced Table Settings** section.

See [Find field, record IDs, and table aliases](https://help.quickbase.com/docs/find-field-record-ids-and-table-aliases).

## Field ID (FID)

A field ID is the number that identifies a field within its table. Most extension parameters that take a field use its field ID, not its name.

1. Open the table and select **Settings** from the table card in the page bar.
2. Select **Fields**. The list shows each field's **Field ID**.

The Record ID# field is always field ID *3*, even if it has been renamed. See [Find field, record IDs, and table aliases](https://help.quickbase.com/docs/find-field-record-ids-and-table-aliases).
