Segment

Probo reads your Segment workspace’s members through the Segment Public API so you can review who has access.

Caution

Create a Public API token, not a Config API token. Segment runs both, and only the Public API token authenticates against the endpoints Probo reads. The Public API is available to Team and Business tier workspaces only, and only a Workspace Owner can create a token, so a Free workspace has none to create.

Prerequisites

• Probo organization administrator access
• A Segment workspace on the Team or Business tier
• The Workspace Owner role in Segment (only a Workspace Owner can create a Public API token)
• The workspace’s Region, which the Connect dialog asks for alongside the token. Segment calls it the data processing region and sets it when the workspace is created; you cannot change it afterwards. New workspaces default to US, and EU data residency is a Business tier feature that a Segment account executive enables, so a Team workspace is always US

Collected Fields

Probo field	Segment field	Notes
Name	name	Falls back to the email address
Email	email
Role	permissions[].roleName	Deduplicated and sorted. A pending invitation carries no role
Admin	permissions[].roleName	Flagged as an administrator when one of the roles is Workspace Owner
Status	invites	Pending invitations are listed as inactive. The users endpoint carries no status for members who have accepted, so theirs is left unknown
MFA	Not supported
Last login	Not supported
External ID	id	Stable identifier used to track the account across reviews. A pending invitation is keyed by its email address
Created at	Not supported

Members who have been invited but have not yet accepted appear alongside accepted members, marked inactive.

Step 1: Create a Public API Token

1. In the Segment app, signed in as a Workspace Owner, go to Settings > Workspace settings > Access Management > Tokens.
2. Click + Create Token, choose a Public API token, write a description (e.g. Probo Access Review), and assign it Workspace Owner access.
3. Click Create, copy the token somewhere secure, and click Done.

Step 2: Connect in Probo

1. In Probo, go to Access Reviews > Sources > Add Source.
2. Find Segment, click API Key, paste the token, choose your Region, and click Connect.

Probo names the source after your workspace and pulls its members into your campaigns.

Troubleshooting

• Token creation is unavailable. The Public API is a Team and Business tier feature, and only a Workspace Owner can create a token. On a Free workspace, upgrade the plan first.
• Token rejected. Confirm it is a Public API token rather than a Config API token, that a Workspace Owner created it, and that the Region matches the workspace. Each region has its own host, and a token authenticates against its own workspace’s host.
• Region unknown. Segment does not document a settings screen that shows an existing workspace’s region, but the URL you sign in with is a practical indicator: app.segment.com is the US app and eu1.app.segment.com the EU one.
• No members appear. A token with only Workspace Member access may not be able to read the workspace’s users. Create one with Workspace Owner access instead.
