Why does the field need both a Hidden setting AND a Field Alias?

Zoho Forms uses Hidden visibility to keep the field off the public form, but it uses Field Alias as the URL parameter name. Without a Field Alias set to `sl_aid`, Zoho ignores the incoming URL parameter and the field stays empty even though it's there. Both settings are required.

I set the field as Hidden but skipped the Field Alias step. Why isn't tracking working?

That's the most common mistake on this integration. Zoho requires the explicit alias to map URL parameters into fields. Add the alias `sl_aid` under Settings -> Field Alias - Prefill URL, save, and try again.

Can I use the existing fields on my form instead of adding a new one?

You can, but you'd need to set the Field Alias of one of your existing fields to `sl_aid`. Adding a dedicated hidden field is cleaner and won't affect your form's UI or data structure for visible fields.

Do I need any Zoho plan in particular?

Webhooks in Zoho Forms are available on paid plans (Basic and above). Free plans don't include webhooks, so submissions won't reach SourceLoop without an upgrade. The hidden-field and Field Alias steps work on any plan.

I share my Zoho Forms direct link in client emails. Will those entries be tracked?

No. Submissions through a raw `forms.zohopublic.com/ /form/...` link won't carry attribution because the visitor never lands on a tracked page first. Embed the form on a landing page that has the SourceLoop snippet.

Zoho Forms is the form builder of choice for businesses already running on the Zoho suite, especially when you need tight integration with Zoho CRM, Zoho Workplace, or any of Zoho’s other tools. The catch most users hit: form entries flow into Zoho with no marketing context attached, no idea which ad, post, or campaign brought the visitor to the form. This guide adds the missing layer.

Four steps, around fifteen minutes. The Field Alias step in step 2 is the one most people miss, watch for it. Webhook support requires a paid Zoho Forms plan.

What SourceLoop captures from Zoho Forms

Every Zoho Forms entry arrives in SourceLoop alongside:

Acquisition channel plus the visitor’s complete UTM parameter set
Browsing sequence before the entry, every page in chronological order
Total time on site before the submission
Session count before they converted
Email and name from the Zoho Forms entry
First-seen landing page and the URL that referred the visitor
Source of the closing session, the one that produced the entry
Device, country, and browser

Before you start

You’ll need:

A SourceLoop workspace (free trial)
Edit access to the website where the Zoho Forms widget will be embedded
A Zoho Forms account on a paid plan (Basic or above for webhook support)
At least one Zoho Forms form built and published

Step 1: Install the SourceLoop tracking script

Log in to SourceLoop, open Setup from the left sidebar, and choose the Tracking code tab. Copy the snippet shown.

SourceLoop Setup page with the tracking code snippet to copy

Drop the snippet inside the <head> of every page on your site, including the page where the Zoho Forms widget will live.

Step 2: Add a hidden field with a Field Alias

Zoho Forms uses Field Alias as the URL parameter name. You’ll need both a hidden field on the form AND an alias set to sl_aid for the integration to work.

Open your form inside Zoho Forms.
Add a new field of type Single Line. Label it anything you like, “SourceLoop Id” works fine.

Open the field’s Field Properties panel.
Under Field Visibility, mark the field as Hide and save.

From the form builder’s left sidebar, navigate to Settings -> Field Alias - Prefill URL.

Find your new field in the alias list and set its alias to exactly:

sl_aid

(lowercase, no spaces, aliases are case-sensitive).

Click Save.

Quick verify: open your form’s standalone URL with ?sl_aid=test123 appended (e.g. https://forms.zohopublic.com/yourname/form/YourForm/formperma/HASH?sl_aid=test123) and submit. The resulting entry should show the field populated with test123. If yes, the alias is wired correctly.

Step 3: Embed the form on your website

Once the form has the hidden field and alias, get it onto your site.

From your Zoho Forms Share tab, choose Embed.
Select Iframe or JavaScript embed (either works).
Copy the embed code and paste it onto your website where the form should appear.

Step 4: Configure the Zoho Forms webhook

The webhook delivers each entry to SourceLoop, where it’s matched to the visitor’s journey and saved as an attributed lead.

In SourceLoop, go to Setup -> Incoming Webhooks and copy your webhook URL.

SourceLoop Setup page on the Incoming Webhooks tab

In Zoho Forms, open your form, go to Integrations -> Webhook, and add a new webhook with the SourceLoop URL.

Set the content type to application/json.

Configure the payload parameters. At minimum, send name, email, and sl_aid. Keep the parameter names exactly as shown below so SourceLoop can read them.

Save.

Submit a test form on your embedded page to confirm the entry appears in SourceLoop with source, channel, and landing page populated.
