Squarespace + Converge

Squarespace integrations come in two shapes, and the difference decides what you can actually add to your site. Squarespace Extensions is a closed, curated catalogue you connect from the Extensions panel; everything outside it — live chat, custom analytics, most third-party scripts — goes in through Code Injection instead. Squarespace's documentation confirms Extensions connect on every plan, while Code Injection is gated to the Core, Plus, and Advanced tiers.

That gate is the most common surprise. Squarespace's current plan names are Basic, Core, Plus, and Advanced, but a large amount of third-party setup advice still points at the older Business and Commerce tiers. If you're on Basic, the Code Injection panel is not in your settings at all, and no widget that ships as a script tag will install until you change plans.

For customer support, Squarespace integrations are thin: of the 45 services in the Extensions catalogue, exactly one — LiveChat — is a chat tool. The other 44 are commerce operations: finance and tax (8), inventory and print-on-demand (14), sales and marketing feeds (15), and shipping and fulfillment (8).

Several extensions sit adjacent to support without replacing it. Delighted runs post-purchase CSAT and NPS surveys, HelpfulCrowd collects product reviews and Q&A, and EZ Texting sends SMS campaigns. All three touch the customer relationship; none of them give you an inbox. If one buyer emails you, DMs your Instagram, and messages your WhatsApp about the same order, no Squarespace extension puts those three in one thread.

So the real decision isn't which extension to install — it's where the conversation lives. The Extensions panel is built around storefront operations, on the assumption that your store syncs to accounting, shipping, and product feeds while support happens in your email client. Teams that outgrow that assumption end up in Code Injection, because it's the only route Squarespace offers to a chat surface it doesn't ship itself.

Paste the widget's script tag into the Code Injection Footer field and save. Squarespace injects Footer code before the closing </body> tag on every page of your site — which is exactly where a chat widget belongs. The panel lives under SettingsAdvancedCode Injection on Core, Plus, and Advanced plans.

Two constraints are worth knowing before you paste anything. Squarespace documents that checkout pages don't support code, so Footer injection never reaches checkout and your chat bubble disappears at the highest-intent moment of the session. And if you run the Squarespace cookie banner in "Opt in & out" mode, scripts added through Code Injection fall under consent, so the widget won't load for visitors who decline.

The post-checkout page is a separate field. Squarespace splits it into an Order Confirmation Page and an Order Status Page, each with its own injection box and merge tags — {orderId}, {orderGrandTotal}, {customerEmailAddress} — plus a {.if firstPageView} guard so a returning shopper doesn't re-fire your scripts. Chat on the order-status screen means pasting the snippet there too, not only in the site Footer.
