ServiceTitan on WordPress Works Fine Until Someone Asks Where the Lead Came From

Four search results, none of them from ServiceTitan

A search of WordPress.org for "servicetitan" on October 26, 2026 returned four plugins. None is published under the ServiceTitan name. One, Advanced Form Integration, is a general form connector that lists ServiceTitan among its destinations. Another, ST Widgets, says it adds ServiceTitan Web Scheduler and Chat to Text source code. It was published by an account called "stuser," last updated on July 11, 2022, and has about 20 active installs. In plugin years, 2022 is roughly the Bronze Age.

ServiceTitan's documentation does not mention ST Widgets, so treat it as unverified, not official. What ServiceTitan does document is a script install that works on almost anything: its Scheduling Pro instructions cover custom sites, WordPress, Wix, Squarespace, GoDaddy and Duda. WordPress is one row in that list, not a special case.

For contrast, and only as a fact, Jobber publishes an official "Jobber WordPress Plugin for Online Booking and Requests" that adds a Jobber block, on select plans. Different companies, different choices. Our platform comparison lays the three side by side without picking a winner.

The install ServiceTitan documents for WordPress

The official route for Scheduling Pro, from ServiceTitan's install article, takes an afternoon. Here it is, with the step most sites skip added at the end.

1. 1

   Add a header and footer plugin

   ServiceTitan suggests an "Insert Headers and Footers"-type plugin without naming one. If your theme or host lets you add custom scripts another way, the plugin is optional.

2. 2

   Paste the main script

   The script carries id="se-widget-embed", data-api-key, data-schedulerid and defer, and loads https://embed.scheduler.servicetitan.com/scheduler-v1.js. ServiceTitan recommends the body section.

3. 3

   Give a button the class

   Add se-booking-show to any button that should open the scheduler, for example in Elementor's CSS Classes field. Adding data-auto-open="true" to the script opens it on page load instead.

4. 4

   Whitelist every domain

   The scheduler will not load unless the site is listed under Scheduler Details. ServiceTitan recommends listing both example.com and www.example.com, plus any staging sites.

5. 5

   Test from a real ad click

   Click your own ad, book a test job, and check the campaign on the record. Avoid the link-style install with the ?se_action= parameter, which reloads the page "and can disrupt lead source tracking."

Sites on the older Web Scheduler 2.0 have a quirk. Its button uses an onclick attribute that, ServiceTitan says, "may not work with the preset button elements" in editors like WordPress, so it recommends a Custom HTML block. ServiceTitan Technical Support "cannot help with installing the web scheduler code," which means the person who owns the website owns the fix.

When the pasted script is all you need

A server-side integration is not a moral obligation. Plenty of contractors are well served by the script and a tidy WordPress site. You are probably one of them if most of these describe you.

If that is you, install the script with custom code as ServiceTitan recommends, whitelist both domain versions, and spend your budget on Google Ads conversion tracking instead. Come back when the forms start to hurt.

Plugin stack or server-side connection, row by row

A fair note before the table: WordPress runs on a server too, and a developer can write a custom plugin that calls ServiceTitan from PHP with the same care as any other server code. The left column describes the stack most contractor sites actually run, not the ceiling of what WordPress can do.

The speed row is where opinions run hottest, so we keep the evidence on separate pages: why WordPress gets slow and the broader WordPress vs Next.js comparison. A clean WordPress site serves real HTML and can rank perfectly well. A site with nine plugins fighting over the header is a different animal.

Forms are where the plugin route runs out of road

Here is the most common ServiceTitan "integration" in the trades: a contact form that emails a shared inbox, which a CSR reads between calls and retypes into ServiceTitan. It works on a slow Tuesday. On the first hot Monday in June it becomes a pile, and the pile has no source, no click ID and no record of which ad paid for it.

A relay improves on the inbox. Advanced Form Integration lists ServiceTitan among its destinations, and ServiceTitan's Zapier integration can push data in to create a task, a job note or an attachment, or to book a job, using a client ID and secret. ServiceTitan says the Zapier integration is provided "'as is'." The question to ask of any relay is what happens at 9 p.m. when a send fails, and where the evidence ends up.

The field-by-field version, from estimate requests to emergency callbacks, is on our ServiceTitan web forms page. The API mechanics, including approvals and the lack of webhooks, are on the API integration page.

Keep WordPress, move the integration, or move everything

Owners assume the choice is WordPress or a rebuild. There are three options, and the middle one surprises people.

• Stay on WordPress and harden the plumbing. Keep the theme, install the scheduler properly, and replace the inbox form with a server-side connection. Least disruption, and still a WordPress site to maintain.
• Keep WordPress for editing, put Next.js in front. Editors keep the dashboard they know while a Next.js front end serves the pages and talks to ServiceTitan from its server. The mechanics are in keeping WordPress as your CMS.
• Move everything. Rebuild on Next.js with Athena CMS, which comes with every custom site we build. The full case for that move is our WordPress to Next.js section, and the ServiceTitan Next.js page covers the integration side.

A plugin is a promise from someone you have never met, renewed every time you click Update.

Rankings are the usual worry with the second and third options. They are protected the boring way: same URLs where possible, a permanent redirect for every one that changes, and titles and structured data carried over by hand, as migrating without losing SEO explains. And if you are not sure you should leave at all, should I leave WordPress argues the other side honestly.

Prices, and a straight answer about your site

Hardening an existing WordPress site's ServiceTitan connection is quoted after a free review; there is no menu price because no two plugin stacks match. A connection between two systems is typically one to three weeks, per our API integrations page.

Rebuilds are a fixed price from $1,750. Sites with a store, portal or web app start at $3,500, and a site with online booking or an estimate flow is about $9,000 on the web design pricing page. Financing for websites runs at 0% with 25% down for up to 12 months.

We build for trades like roofing and plumbing from San Antonio, Texas, for businesses across the US. Before any launch, run the ServiceTitan website checklist. The rest of the section is on the ServiceTitan integration hub, or call (210) 346-0848.
