WhatsApp: Start Chat Button
Installation and user guide by Certified Code
Install and connect your number
- Install the app from the BigCommerce App Marketplace and approve its requested permissions.
- Open Apps → My Apps → WhatsApp: Start Chat Button.
- Under Representatives, enter a support name and a WhatsApp number including its country code. Use 7–15 digits without a plus sign, spaces, or punctuation. Use a number connected to your own WhatsApp account.
- Optionally enter an availability note and a pre-filled customer message.
- Click Save settings. Then turn on Enable button.
- Open your storefront using View store in BigCommerce. For private stores, use an authenticated preview or enter the store preview code.
- If the store uses a cookie consent banner, allow functional cookies. The chat button uses the functional category.
Customize and preview
Edit the button position, colors, speech bubble, support contact, and chat content in the dashboard. Use the interactive preview to inspect your unsaved changes, then click Save settings to apply them. The preview does not send a WhatsApp message.
Premium settings are labeled in the dashboard. They include advanced appearance, behavior, page visibility, and availability controls. Check the plan panel for the current monthly price before upgrading.
Mobile, pages, and availability
Enable Show on mobile for shoppers using a phone. With page visibility enabled, allow-list rules show the widget only on matching paths; block-list rules hide it on those paths. Enter one path per line, such as /contact-us/ or /products/*. An empty allow list hides the widget everywhere.
Weekly availability controls online and offline status. Use HH:mm-HH:mm ranges, such as 09:00-17:00; turn a day off for unavailable days. The widget evaluates availability using the visitor’s detected timezone.
Upgrade or cancel
Click Upgrade to Premium, then Continue to BigCommerce checkout. Review the price and complete payment there. Return to the app after checkout; the app verifies your subscription before enabling Premium controls.
To cancel renewal, open Plan and support, select Cancel Premium subscription, and confirm. Access continues until BigCommerce ends the subscription. Trials or subscriptions that have not been invoiced may end immediately.
If the button is missing
- Confirm at least one valid WhatsApp number is saved and the storefront script is enabled.
- Allow functional cookies and refresh the storefront.
- Check mobile visibility and page restrictions, especially an empty allow list.
- Make sure you are viewing the storefront, rather than the private-store Coming Soon page or checkout.
- Check whether a browser extension blocks chat assets. If it still fails, contact support with your store URL and the error shown.
Disable or uninstall
Turn off Enable button to hide it. Uninstall the app through BigCommerce’s My Apps screen to remove its storefront script automatically.
