## Description

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).

## Installation

 1. Upload the plugin ZIP via Plugins  Add New  Upload Plugin, or upload the `sello-
    crm` folder to `/wp-content/plugins/`.
 2. Activate the plugin through the Plugins screen.
 3. Generate an API key in your Sello CRM dashboard at Settings  API Keys.
 4. Open the new “Sello CRM” entry in your WordPress admin sidebar and paste the key.
 5. Click “Test connection” to verify the credentials work and see which campaign the
    leads will be attached to.
 6. Done. Forms on the site now send leads to Sello CRM automatically.

## FAQ

### Will this break my existing forms?

No. The plugin is a passive listener — it does not call `event.preventDefault()`
or interfere with form submission. Your forms keep working exactly as they did before.

### Do I need to disable my existing form-to-email integration?

No. Sello CRM Form Capture runs alongside whatever you already have. It listens 
to the same submit event without consuming it.

### What if my form fields have opaque names like `your-text-field-3`?

The plugin classifies fields by both name AND value shape. A field named `field_3`
containing `john@example.com` will still be detected as an email. Phone numbers 
with 9–15 digits (after stripping spaces and punctuation) are matched the same way.

### How do I rotate the API key?

Paste a new key on the settings page. There is no “view current key” — Sello CRM
shows the key only once at creation, both server-side and client-side.

### Can I see what’s being sent?

Enable “Debug logging” in the plugin settings. Capture activity will be logged to
the browser console (the user’s, not the admin’s — the script runs on the front-
end).

### What gets filtered out?

WordPress nonces, CSRF tokens, captcha responses (reCAPTCHA, hCaptcha, Turnstile),
password fields, file uploads, and any field whose name starts with `_` (system 
fields). Forms without any email or phone field are skipped entirely — search bars,
login forms, and comment forms never reach Sello.

## Changelog

#### 1.0.2

 * Compliance: moved the “Test connection” inline `<script>` block to `assets/sello-
   admin.js` and registered it via `wp_enqueue_script` + `wp_localize_script`, per
   WordPress.org plugin guidelines.
 * Compliance: documented the use of Sello CRM as an external service in the readme(
   External services section with terms + privacy links).
 * Compliance: removed the manual `load_plugin_textdomain()` call — WordPress.org

#### 1.0.1

 * Settings page: API key + endpoint laid out side-by-side; brand logo centered 
   with transparent background.

   placeholder).
 * Settings link now points to `/settings/integrations` (WordPress tab) on the Sello
   CRM dashboard.
 * Removed the Debug log toggle from the settings UI.

#### 1.0.0

 * Initial release.
 * Document-level capture-phase submit listener — works with any form, including
   dynamically-injected ones.

 * UTM + referrer + Meta tracking forwarding for full Smart Attribution on the server
   side.
