Creating segments

Learn more about segments in Reflag

What segments are

Segments are reusable audiences built from companies, users, or both together.

You build them from filters such as company lists, user lists, company attributes, user attributes, flag access, and flag metrics.

Use segments when you want to save an audience once and reuse it across multiple flags in access rules.

Create a segment

1. Open Segments in the sidebar.

2. Click Add filter +.

3. Add the conditions for the companies, users, or combined audience you want to include.

4. Save the segment.

Choose segment conditions

Each segment uses one or more conditions. Add as many conditions as you need.

Condition types

You can build a segment from these condition types:

• Company attribute — match company data such as plan IS 'pro'

• User attribute — match user data such as role CONTAINS 'admin'

• Company list — search by company name or paste company IDs

• User list — search by user name or paste user IDs

• Flag access

  • Is enabled

  • Is not enabled

• Flag metric

  • Track count

  • Exposure count

  • First track

  • Last track

• Segment

  • In segment

  • Not in segment

How conditions work

All conditions in a segment must match.

That means segment conditions work like AND.

You can combine company conditions and user conditions in the same segment.

Common examples

• Pro customers — Company attribute: plan IS 'pro'

• Admin users at beta companies — User attribute: role CONTAINS 'admin' and Segment: In segment 'Beta customers'

• Companies with access to a flag — Flag access: [Flag name] is enabled

Available operators

Operators depend on the condition type:

• Any

  • Is

  • Is not

  • Has any value

  • Has no value

• Text

  • Contains

  • Does not contain

• List

  • Is any of

  • Is not any of

• Number

  • Less than

  • Greater than

• Boolean

  • Is true

  • Is false

• Date

  • Less than X days ago

  • More than X days ago

  • Before date X

  • After date X

• Flag access

  • Is enabled

  • Is not enabled

• Segment

  • In segment

  • Not in segment

These attribute operators are also available when you create flag access rules.

Array attributes

Attributes can hold arrays such as roles: ["admin", "editor"]. Array operators compare whole items and are case-sensitive: admin does not match Admin or part of a value such as adm.

Operator	Matches an array when
Is	It has exactly one item, equal to the selected value.
Is not	It is empty, has more than one item, or its only item differs from the selected value.
Contains	It includes the selected value.
Does not contain	It does not include the selected value.
Is any of	It includes at least one selected value.
Is not any of	It includes none of the selected values.
Has any value	It has at least one item.
Has no value	It is empty.

For example, roles: ["admin", "editor"] matches Contains admin and Is any of [admin, owner], but it does not match Is admin.

Number, date, and boolean operators do not support arrays, and arrays cannot be used for percentage rollouts. If an access rule applies an unsupported operator to an array, that rule does not match.

Save and reuse the segment

After you save a segment, you can reuse it in flag access rules and rollout workflows.

You can create as many segments as you need.
