Sello CRM Form Capture watches every form submission on your WordPress site and forwards leads to your Sello CRM account in real time. It works with any form on the site — Elementor, Contact Form 7, WPForms, Gravity Forms, Forminator, native HTML forms, popups — without per-form mapping or shortcodes.

How is this different from a regular form-to-CRM integration?

Most CRM plugins ask you to wire up each form individually: pick a form, map its fields, save settings, repeat for every form you ever build. Sello CRM is a single document-level submit listener that automatically detects every form on the site, classifies its fields (email, phone, name, etc.), and sends the matching leads to Sello CRM.

• No shortcodes
• No per-form mapping
• No replacement form handler — your existing thank-you pages, autoresponders, and server-side handlers keep working exactly as before
• Catches forms in popups, AJAX-loaded modals, and dynamically-injected widgets

Smart Attribution

The plugin reads the page’s UTM parameters (utm_source, utm_medium, utm_campaign, utm_term, utm_content, gclid) and the document referrer on every submit, plus the Meta tracking cookies (_fbp, _fbc, fbclid) when present. UTM values persist in sessionStorage across page navigations within the visit, so a click on a tagged ad is correctly attributed even when the visitor browses around before submitting.

Sello CRM’s server-side attribution then matches utm_campaign to a real campaign in your account so cost-per-lead and ROI are calculated automatically against the matching Meta/Google ad spend.

Privacy

The plugin only sends data when a form is submitted that contains an email or phone field. No background telemetry, no admin-side beacons, no third-party analytics. Form data is sent directly to your Sello CRM endpoint over HTTPS, authenticated with the API key you configured. Password fields, file uploads, WordPress nonces, CSRF tokens, and captcha responses are filtered out automatically and never leave the page.

External services

This plugin relies on a single third-party service — Sello CRM — to receive and store the captured leads. Sello CRM is the SaaS product this plugin is built for, operated by Sello CRM Ltd.

What the service is and what it is used for:
Sello CRM (https://crm.sello.co.il) is a marketing-operations CRM that stores incoming leads, attributes them to the matching ad campaign, and exposes them in the user’s dashboard. Without this connection the plugin has no purpose — there is no “local-only” mode.

What data is sent and when:
Data is sent only when a visitor submits a form on your site that contains an email or phone field. On submit, the plugin POSTs the following to https://crm.sello.co.il/api/webhooks/universal/leads (or the custom endpoint configured in the settings page):

• The form’s field values that the plugin classified as contact fields (email, phone, name).
• The page’s UTM parameters (utm_source, utm_medium, utm_campaign, utm_term, utm_content), gclid, and the document referrer.
• Meta Pixel tracking cookies (_fbp, _fbc) and fbclid from the URL, when present, for ad attribution.
• The configured API key in the Authorization header for authentication.

In addition, when the site administrator clicks the “Test connection” button on the plugin’s settings page, a single authenticated GET request is sent to https://crm.sello.co.il/api/webhooks/universal/test to verify the API key and return the campaign name the leads will be attached to. No visitor data is sent in this test request.

No data is sent in the background, on page load, on admin page views, or for forms without contact fields (search bars, login forms, comment forms).
