# Test a LinkedIn Lead Gen Form

By HeyMark · Updated November 4, 2026

Before launching a campaign with a LinkedIn form, check that you can receive the details someone submits. Send a test lead from Campaign Manager and find it in the CSV. If you use a CRM, also check that the contact and its fields arrive there.

## Before you start

You need access to the correct ad account in Campaign Manager and a Lead Gen Form associated with it. To download the test, you need **Viewer** access or higher on the ad account and **super admin**, **content admin**, **analyst**, or **Lead Gen Forms Manager** access on its Page. If a Business Manager owns the ad account, the Page must belong to that same Business Manager. See [LinkedIn’s download permissions](https://www.linkedin.com/help/lms/answer/a425750). Prepare test details for every required field. LinkedIn lists first name, last name, and email address.

## Send the test lead

1. Open the correct ad account in Campaign Manager.
2. Select **Content & Assets**, then **Lead generation forms**.
3. Find the form. Open **More** in its row and select **Send Test Lead**.
4. Complete all fields marked as required and select **Send**.

LinkedIn also documents a route through the preview of an ad creative that uses the form. If the form is attached to a specific creative, you can open its preview and submit your details there. The **More** route is the direct way to find the form.

## Check the download

In **Lead generation forms**, select the form’s checkbox, choose a date range that includes your test, then select **Download leads → Download**. Open the downloaded CSV. LinkedIn says the download can be disabled when the form has generated neither real nor test leads. If you sent only a test, the count can still show zero while the download is available.

Open the report and check the **Test Lead** column. **TRUE** identifies a test lead; **FALSE** identifies a real lead. If you repeat the process, remember that sending a new test lead overwrites the existing test lead.

If you use a CRM, check that the contact arrived there and each field matches what you submitted.

## If the test does not appear

- Confirm that you opened the right ad account and form.
- Check whether **Download leads** is enabled. LinkedIn says it can be disabled when there are no real or test leads.
- If you downloaded the report, find **Test Lead** and confirm it says `TRUE`.
- Consider that a new test submission replaces the previous one.

See [LinkedIn’s instructions for sending a test lead](https://www.linkedin.com/help/lms/answer/a420737) for access requirements and the alternative Ads preview route.

If the ad still needs its form attached, follow the steps to [attach a Lead Gen Form to your LinkedIn ad](https://heymark.ai/en/solutions/attach-lead-gen-form-linkedin-ad/).
