# IDX Broker agent subheaders and attribution

An agent-specific header should agree with the person who receives the inquiry. Check both results when agents share an office IDX website.

IDX Broker describes a feature that uses a browser cookie to show an agent's custom subheader on the office IDX site. It also attributes the lead to the referring agent. Its documented entry points are the agent's biography page and IDX links carrying the assigned agent tag. [IDX Broker's agent attribution feature](https://www.idxbroker.com/features/agent-lead-assignment-and-subheader). Checked: 2026.10.23.

Use the following acceptance brief to inspect your installation. The feature description does not establish how your account handles competing tags, missing cookies, or existing contacts.

## Map the referring agent to the receiving record

Prepare one row for each participating agent. Record their public name, approved biography address, vendor-assigned tag, and intended inquiry destination.

Have the provider supply the actual tagged links. Avoid guessing identifiers from a name, public profile address, or MLS number.

Keep these identifiers labeled according to the vendor's terminology. A marketing tag and an MLS identity serve different tasks. Ask the provider to explain any mapping between them in your installation.

Choose a default contact route for visitors who arrive without an agent reference. Make that destination explicit in the website brief.

## Inspect what the subheader says

Approve the visible name, role, brokerage identity, and contact wording before testing assignment. Review these details against your broker's applicable advertising requirements.

Use the [team and brokerage identity brief](/articles/team-brand-versus-brokerage-brand-hierarchy) to organize that review. Keep any state-specific sizing or placement question with the broker.

Write contact labels that describe the actual next step. If a coordinator receives the inquiry, have the approved wording explain the handoff.

Do not accept a correct-looking header as evidence that the corresponding contact record or destination is correct.

## Agree on the difficult cases before testing

Ask the provider to describe the expected outcome for each case. Leave an unanswered behavior marked UNRESOLVED until it is demonstrated.

| Visitor path | Question to settle | Evidence to inspect |
| --- | --- | --- |
| Agent biography to property search | Does the intended agent remain identified? | Visible header and received inquiry |
| Tagged link to a property detail | Is the referring agent carried through? | Entry link, detail page, and contact record |
| Untagged office homepage to search | Who receives a general inquiry? | Default identity and destination |
| One agent's link, then another's | Which reference takes precedence? | Vendor explanation and observed assignment |
| Return visit with prior browser state | Does the previous reference remain active? | Agreed repeat-visit result |
| Storage unavailable or consent declined | What fallback applies? | Visible wording and actual destination |
| Existing registered visitor | Does a new reference alter ownership? | Authorized account review and documented policy |

These are proposed checks. They describe no verified behavior of a particular account.

Keep visual attribution, inquiry assignment, and any later CRM distribution rule as separate observations. Record where each decision occurs.

## Request controlled delivery evidence

Arrange tests with the account owner and receiving agents. Use contact details you control and an unmistakable test label.

For a clean-session check, ask the tester to begin without prior site storage. For a return-visit check, retain the agreed prior state. Record which condition applies.

Open the supplied link, follow the search path, and inspect the identity shown beside the contact action. Submit the agreed test and compare the received record.

The acceptance record should include the entry address, expected agent, observed header, recipient, and date. Redact personal information and account secrets from shared screenshots.

For a wrong result, send support the smallest reproducible path. Include the expected behavior rather than changing multiple assignment settings at once.

## Include agent departures in the handoff

Agree what happens to an agent's old tagged links and biography after departure. Identify the person authorized to approve a replacement destination.

Repeat the default-path and old-link checks after that change. Keep general website inquiries under the brokerage's approved assignment policy.

For a wider distribution redesign, use the [multi-agent inquiry rules brief](/articles/multi-agent-website-lead-routing-rules). Keep its acceptance work distinct from this feature's referral attribution checks.

## Scope the repair around the failed path

Bring the agent mapping, failing entry links, expected outcomes, and received test records to the [website scope form](/work). Ask for a repair that closes the documented attribution fault.
