Why Use BlooTrue for BBB on OpenCart?

The only free way to put BBB reviews on your OpenCart storefront — BBB itself doesn't offer an embed.

Fills BBB's Missing Embed

BBB doesn't publish an official embed widget for merchants. BlooTrue is the free, paste-and-go alternative — pulls reviews from your public BBB business profile automatically.

No OpenCart Extension Required

Pure HTML embed. No marketplace purchase, no vQmod / OCMOD patch, no PHP file edits. Pastes into the core CMS Information system or the bundled HTML Content module.

Works on OpenCart 3.x and 4.x

Same install path on both major versions. The Source toggle in the editor and the HTML Content module from Extensions → Modules exist in core on both 3.x and 4.x.

No BBB API Key Required

Works with any public BBB business profile. No BBB Fusion application, no API quotas, no business-level claim required.

What makes a BBB widget different from a Google review widget?

BBB customer reviews are a native 1–5 star system. Knowing how they differ from BBB's A+-to-F letter rating, how profile setup works, and how reviews are moderated avoids surprises after you embed.

BBB customer reviews vs the A+-to-F “BBB rating”

BBB has two separate signals, and this widget shows only one of them. The first is the 1–5 star customer reviews — written by your customers about their experience — with an overall customer-review average; that's what BlooTrue displays. The second is the A+-to-F letter “BBB rating”, which is BBB's own grade for how a business interacts with BBB (complaint history, transparency, time in business, accreditation status) — the widget does not show this letter rating or the accreditation seal. BlooTrue renders each customer review exactly as stars: a 5-star review shows 5 stars, a 3-star review shows 3, and the header shows your real BBB customer-review average and count. The header rating always comes from BBB's own published customer-review aggregate, never from averaging the individual cards on screen.

Where the reviews come from and how often they refresh

BlooTrue fetches the publicly-visible customer reviews from your BBB business profile on a server-side schedule — roughly once every 24 hours on paid plans — and caches the result. Your site never calls BBB directly, so visitor traffic to your page doesn't depend on BBB being reachable, and the widget loads instantly from cache. Only reviews that are public on your profile are included. Each review keeps its reviewer name, star rating, and text, and links back to your BBB business profile.

Accreditation, profile setup, and what shows up in the widget

You do not need to be a BBB Accredited Business to use this widget — it works with any public BBB business profile, accredited or not. Reviews only appear if your profile is public and has customer reviews. If your profile is brand new or has zero reviews, there's nothing for the widget to import yet — it will populate as soon as your first public customer review lands. Once your profile has reviews, the widget shows whatever is public: no more, no less. If a review disappears from your widget after a sync, it almost always means the customer deleted it or BBB removed it — the widget simply follows your profile's public state.

Moderation, review guidelines, and attribution

BBB moderates customer reviews under its review guidelines and removes spam, fraudulent submissions, and content that violates its policies. Because BlooTrue reads only your profile's public reviews, the widget automatically reflects those removals on the next sync — you never display content BBB has already taken down. Every card keeps the BBB mark and the reviewer's name, and clicking a review links back to your BBB business profile, so attribution stays intact. BlooTrue never fabricates a rating: an empty star-only review (a star rating with no written text) is still shown as a real review, and the header number is always BBB's own customer-review aggregate.

BBB tips for OpenCart

OpenCart's HTML Content module is the right mount point for the BBB widget — not the Product Review module.
For multi-store OpenCart installations, embed a BBB widget per store with each store's respective BBB business profile.
The BBB widget runs independently of OpenCart's built-in review approval workflow.

How Do I Install BlooTrue BBB on OpenCart?

Takes less than a minute. No coding, no extension, no BBB API key.

Decide Where The Reviews Go

Log into your OpenCart admin and pick the placement:

A static Information page — Catalog → Information.
A sidebar or footer module using the bundled HTML Content module — assigned via Design → Layouts.

For a CMS Page: Catalog → Information

In the OpenCart admin, open Catalog → Information, edit the target page. In the rich-text editor toolbar, click the Source button (looks like </>) to switch to raw HTML view.

Paste the BlooTrue embed code there. This step is critical — if you paste in the visual view instead, OpenCart sanitizes the<script> tag and the widget disappears on save.

Save the page. Visit the storefront URL — your BBB reviews are live.

Or Use the HTML Content Module

For sidebar / footer / homepage placement, open Extensions → Modules, find HTML Content (a core module — already installed in OpenCart 3.x and 4.x), click Add Module, give it a name like "BBB Reviews", click the Source button in its editor, and paste.

Assign to a Layout and Publish

Open Design → Layouts, pick the layout to target, and add the HTML Content module to a position — Column Left, Column Right, Content Top, Content Bottom, or Footer.

Save the layout. Reviews auto-sync from BBB every 24 hours.

BBB Review Widget for OpenCart — Free, Fills BBB's Embed Gap

BlooTrue's BBB Review Widget for OpenCart is a free, extension-free embed that displays your BBB reviews on any OpenCart storefront. BBB does not provide an official embed widget for merchants — its Fusion API is gated for partner apps like Apple Maps and Trivago, not for self-service merchant embeds. BlooTrue fills that gap by pulling reviews from any public BBB business page and turning them into a paste-ready OpenCart embed. OpenCart is a free, open-source PHP e-commerce platform widely used in MENA, Eastern Europe, and South-East Asia, and it ships with both a CMS Information system (Catalog → Information) and a bundled HTML Content module (Extensions → Modules) — BlooTrue pastes into either. No OpenCart marketplace purchase, no PHP edits, no BBB API key, no BBB Fusion application, no business-level claim required. Works on OpenCart 3.x (the dominant deployed version) and OpenCart 4.x with any theme. The single biggest install gotcha is the Source button (the </> toggle that switches the editor between WYSIWYG and raw HTML) — without clicking it, the visual editor escapes the embedded<script> tag and the widget disappears on save.

Why doesn't BBB have an official embed?

BBB's Fusion API is positioned as a partner-channel product (used by Apple Maps and Trivago) rather than a merchant self-service product. BBB does not publish a paste-ready embed widget the way Google publishes Place Cards. Third-party widgets are the standard way OpenCart stores surface their BBB reviews — BlooTrue is the free option in that category.

About BBB reviews in this widget

A BBB widget carries the customer reviews posted on your BBB business profile, each with the 1 to 5 stars the customer gave. The figure in the header is the profile's customer-review star average and how many reviews BBB lists, never the letter grade: the A+ to F rating is BBB's own grade for how your business deals with BBB, complaints included, and stays separate from what customers write. Accreditation is not required. Some owners paste the BBB Accredited Business seal expecting reviews, but the seal only displays the letter grade and accreditation status.

Frequently Asked Questions

Can my A+ BBB rating be the number in the widget header?

No. The header shows the star average of your BBB customer reviews, pulled from your public profile, together with the review count. The A+ to F letter grade is BBB's own assessment of how you interact with BBB and stays separate from customer reviews, so a profile can hold an A+ alongside a 3-star average.

I am not BBB accredited, can I still put my BBB reviews on my site?

Yes. Accreditation is a separate BBB status and the builder does not check for it; it reads any public BBB business profile from its URL, accredited or not. The BBB Accredited Business seal is a different thing again: it displays your letter grade and accreditation status, not the customer review cards you want on the page.

Do BBB complaints show up in the review widget?

No. BBB keeps complaints and customer reviews as separate records on your profile, and the widget imports only the 1 to 5 star customer reviews. Complaints feed into the letter grade, which the widget does not show. A free widget shows the customer reviews as of the day you built it; paid plans re-check your profile daily.

Is the BlooTrue BBB widget free for OpenCart?

Yes. BlooTrue is completely free for OpenCart. No marketplace extension purchase, no recurring license fee, unlimited widget views, no credit card. The free plan shows your BBB reviews with BlooTrue branding in the footer.

Does BBB offer its own embed widget for OpenCart?

No. BBB does not provide an official embed widget for businesses to display their reviews on a storefront. BBB's Fusion API is gated and primarily intended for partner apps, not merchant self-embeds. BlooTrue fills that gap by pulling reviews from any public BBB business page and turning them into a paste-ready OpenCart embed.

Do I need a BBB API key or BBB Fusion access?

No. BlooTrue works with any public BBB business profile — no BBB API key, no BBB Fusion application, no business-level claim required. Just paste your bbb.org/./profile/your-business-slug URL into the BlooTrue builder.

Why does my embed code disappear after I save the OpenCart page?

Because you pasted into the WYSIWYG (visual) editor, which strips or escapes the <script> tag. Click the Source button (looks like </>) in the editor toolbar to switch to raw HTML view, paste the embed code there, and save. The Source toggle is the #1 install gotcha on OpenCart.

Does this work on both OpenCart 3.x and OpenCart 4.x?

Yes. The embed is pure client-side HTML and JavaScript and the install path (Source toggle in the editor, HTML Content module from Extensions → Modules) exists in both major versions.

Where exactly should I paste the embed code on OpenCart?

Two paths. (1) For a static page (About, Reviews, Testimonials): Catalog → Information → edit the page → click the Source button (</>) in the editor → paste. (2) For sidebar/footer placement: Extensions → Modules → install HTML Content → edit it → click Source → paste → assign via Design → Layouts.

Will the widget slow down my OpenCart store?

No. The widget loads asynchronously after page content, so it never blocks rendering. The script is under 20KB and reviews are served from a CDN cache. Typical impact on Largest Contentful Paint is under 50ms — well within Google's Core Web Vitals thresholds.
