On Starter, **Connections** shows **Part of Pro** with an **Upgrade to Pro** button, and making a URL or adding the trigger shows **Part of Pro: Lead forms (Typeform, Tally, Jotform...)** with the same button. URLs and triggers you already have keep adding contacts on every plan. See [Plans and billing](/help/account/billing.md). Running landing pages on Unbounce? Everyone who submits the form can become a contact in Kerux and start the campaign you choose. No Zapier or Make in between: Unbounce sends each submission straight to a secret URL of your workspace, and Kerux reads Unbounce's own format. ## Connect Unbounce **1. Make your secret URL in Kerux** Go to **Integrations > Connections**. In **Forms**, click **Connect** on the **Unbounce** row: a side panel opens. Under **Name your first URL**, type a name you'll recognize (for example *Demo request*) and click **Create URL**, then **Copy**. Keep it private: anyone with this URL can add contacts to your workspace. **2. Add the webhook in Unbounce** In Unbounce, open your page's **Page Overview**, then the **Integrations** tab and the **Webhooks** tab. Click **+ Add Webhook**. **3. Paste your URL** Paste your Kerux URL. Leave the content type as it is (the default, form fields) and click **Save Changes**, then **Done**. **4. Send a test** Visit the live page and submit a test. In Unbounce, the contact's **Integration Details** show a green check; in Kerux, the URL's card shows its fields. Kerux reads Unbounce's `data.json` field, names each field after its form field ID (for example `email`, `full_name`), and leaves out Unbounce's page details (IP address, variant, page URL). Each landing page is its own form in Kerux, so a campaign can start from only one page. Popups and sticky bars use the same steps. ## Choose where each field goes When the first submission arrives, the URL's card in the panel stops saying **Waiting for your first submission...** and shows **Where each field goes**: every field of that submission (only the field names, never the answers) and where Kerux puts it. * **Automatic** is Kerux's guess. It uses the field's type when Unbounce sends one (an email question is the email), then the question's words (*First name*, *Company*, *Job title*, *Phone*...), and any answer that is an email address or a LinkedIn profile URL. * Pick another target to change it: **Email**, **First name**, **Last name**, **First and last name**, **Phone**, **Company**, **Job title**, **Location**, **Address**, **City**, **Country**, **Postal code**, **LinkedIn profile**, a **Custom field** (use it in messages as `{{contact.custom.}}`), or **Don't keep**. * Click **Save mapping**. Every next submission uses it. **Test** shows how a sample Unbounce submission (taken from Unbounce's documentation) would be read with your mapping. Nothing is saved and no contact is made. ## Start a campaign from the form **1. Add the trigger** Open your campaign, go to its **Triggers** tab and click **+ Add** > **Lead form submitted**. **2. Pick the source** Under **Source**, pick **Unbounce**. Under **Which URL**, pick one of your Unbounce URLs or **Any Unbounce URL**. Leave **Every form**, or pick **Only these forms** once a submission from them has arrived. Click **Add the trigger**. Pick **Any source (every lead form and form tool)** instead to start the campaign from every form and every Facebook / Instagram lead ad at once. ## Good to know * **No LinkedIn profile? They still come in.** People without a LinkedIn URL become contacts by their email. Email and other steps run; LinkedIn steps wait (shown in **Home > Tasks** with the reason *missing LinkedIn URL*) until someone adds their profile, then continue by themselves. * **Never twice.** Unbounce may send the same submission again (a retry, a test sent twice): Kerux recognizes it by its answers (Unbounce sends no submission id) and adds the person once. Someone who is already a contact is updated: empty fields are filled, their answers are saved as custom fields. * **One URL per form.** Make as many URLs as you like (**Add another URL**), so each campaign can pick its own. * **If the URL leaks**, click **Make a new URL** on its card: the old one stops working at once. Paste the new one in Unbounce. **Turn off** stops the URL for good. * **Limits.** Each URL takes up to 60 requests a minute; more get an answer to try again later. A body can be up to 256 KB. * Only workspace owners and admins can make URLs and see them. Members see **Ask an admin** on the row. * Answers are data, never instructions: whatever someone types in your form is stored as text, nothing else. ## With the API The same URLs are in the public API: `GET /v1/integrations/form-relays`, `POST /v1/integrations/form-relays` (`{"tool": "unbounce", "name": "Demo request"}`), `PATCH /v1/integrations/form-relays/{id}` (rename, or `mapping`), `POST /v1/integrations/form-relays/{id}/rotate`, `POST /v1/integrations/form-relays/{id}/test`, `DELETE /v1/integrations/form-relays/{id}`, and `POST /v1/workflows/{id}/lead-form-triggers` (`{"provider": "unbounce", "page_id": "*"}`). See [the API](/help/developers/api.md). ## Sources * Unbounce: [Using a Webhook](https://documentation.unbounce.com/hc/en-us/articles/203510044-Using-a-Webhook). > [!NOTE] > > Kerux reads Unbounce's webhook as Unbounce's documentation describes it.
