### Understanding the main screen

In the fields list you will see the columns:

* **First name**: the label that appears to the user.
* **Type**: defines the data format (Text, Email, Phone, CPF, State, Country etc.).
* **Alias**: technical name, automatically generated from the “Name”, used internally in integrations and APIs.
* **Group**: category to which the field belongs (for example, “Personal Data”, “Primary” etc.).
* **Required**: indicates (with a *asterisk*) that the user **must** fill in this field when creating or editing a lead.
* **Unique Identifier**: when checked, indicates that the value of this field will be used to detect lead duplicates and allow merging or ignoring repeated records.
* **Actions**: edit/delete buttons.

***

### What each setting is for

* **Required**\
  Required fields ensure that essential information (such as Email or CPF) is always filled in before creating a lead.
* **Unique Identifier**\
  Prevents duplicate leads: when importing or creating new records, Sprinthub checks this field and, if the value already exists, suggests merging with the previous lead or discarding the creation.
* **Alias**\
  It is the field’s “code name” within the system and in automations via API. You do not need to edit it manually: it is automatically generated from the readable name.
* **Group**\
  Groups fields by area of interest. Besides visually organizing the lead form, each group can have its own color and icon to facilitate identification.

### How to create a new custom field

<figure><img src="/files/686fb1b69ec3f625606ebf00d4c7d0a13c7506cb" alt=""><figcaption></figcaption></figure>

* **First name**: text that the user will see when filling out the lead.
* **Type**: choose the desired data format (free text, number, date, email, phone, CPF etc.).
* **Group**: select the existing category. If you want, click the pencil icon next to the group to **change color and emoji** that will identify this set of fields.
* **Alias**: will be filled automatically; no need to edit.
* **Default Value**: optional option to pre-load a value when the lead is created (useful for status or fixed source fields).

In **Modifiers** (on the left), enable:

* **Required?** to force completion.
* **Unique Identifier?** to use this field in deduplication logic.
