LINE Chat Integration: setup and help

On older PrestaShop versions, use the equivalent module installation page. Open this module through Configure whenever you need to return to its settings.

After you save an identifier, the configuration page provides a link to open the LINE account. Open it to check the destination. The module checks the format of changed identifiers when you save, without checking whether the account exists. A rejected edit keeps the previous configuration; unchanged identifiers are kept without another format check.

You can translate Button Text and Tooltip Text using the form language controls. An empty translation follows the default language. The same language fallback applies to Pre-filled Message. Use Save after editing.

Checkout Pages Only matches cart, order, order-opc, orderopc, and checkout. Other checkout modules can use different controller names. The fallback wait starts on the page. It is not an additional delay after an interaction.

Your theme must render displayHeader for the stylesheet and displayBeforeBodyClosingTag for the widget. The module checks the enable switch, a non-empty identifier, the mobile rule, and the page rule before returning output.

After the first interaction or fallback, you see a fixed button in the selected corner. Its link opens in a new tab with noopener noreferrer. For Official Account @myshop without a message, the destination is:

https://line.me/R/oaMessage/%40myshop

Use a personal LINE ID or Official Account ID, such as myshop, @myshop, shop.name, shop-name, or shop_name. Personal ID myshop links to https://line.me/ti/p/myshop. For an Official Account with a saved message, the module appends /? and the URL-encoded message to the Official Account URL, replacing {url} with the current page URL. You handle conversations in LINE. The module does not generate QR codes, send order notifications, or provide an inbox.

Test one allowed page and one excluded page if you restrict page types. Test mobile visibility on a real device. If you use multiple languages, check the translated button text and tooltip.

For a text button on product pages, set Button Style to Bar with Text, Button Text to Ask us on LINE, Show on Pages to Product Pages Only, and Animation to none. You can choose Bottom Left when another widget uses the right corner.

If you need to move the widget above another fixed control, add a rule to your theme stylesheet:

#mprline-widget.mprline-bottom-right {
  bottom: 90px;
  right: 24px;
}

#mprline-widget.mprline-bar a span {
  font-size: 15px;
}

For a theme template override, use:

themes/your-theme/modules/mprlinechatintegration/views/templates/hook/displayBeforeBodyClosingTag.tpl

The template receives $mprline with chat_url, position, style, cta_text, color, size, margin, show_tooltip, tooltip, animation, and delay. The prepared chat_url includes the message for Official Accounts; separate line_id and message fields are not supplied. Keep changes in your theme so a module update does not overwrite them.

Settings use the shared mpr_config table with the configured database prefix, the module name mprlinechatintegration, and short keys such as LINE_ID, POSITION, STYLE, CTA_TEXT, and COLOR. The form field names use the MPRLINE_ prefix. Change settings through the form.

• If you see no button, check the enable switch, saved identifier, page rule, and mobile rule. Trigger an interaction or wait for the fallback.
• If an edit is rejected, enter the identifier format listed above. Do not paste an entire contact link.
• If the widget has no styling, check that your theme calls displayHeader and loads the module stylesheet.
• If the template never appears, check displayBeforeBodyClosingTag and the module’s hook registration in the back office.
• If the button overlaps another control, change Position or Margin from Edge (px).
• If the button appears but the destination fails, test the saved contact and the device’s external app handler.

If a prefilled message is missing, use an Official Account ID starting with @ and test the storefront button on iOS or Android. Personal IDs open the contact without a message. The back-office test link checks the account only and does not include the saved message.

Use the module’s Integrity page for setup and hook diagnostics. License, Support, and Update are maintenance pages rather than storefront appearance settings.

Turn off Enable LINE Chat and save to retain your configuration. The main form still requires a non-empty identifier when you save. You can also disable the module from the module list.

Use Uninstall in the module manager to remove the module configuration and its admin menu entries. Your external messaging account is not deleted.
