For a shopper-friendly overview of features and setup, see the Magento 2 Constant Contact User Guide - Sync Customers & Subscribers on the storefront. This wiki page remains the full technical documentation.

This is a Toweringmedia Magento 2 extension guide for the current admin extension catalog.

• Toweringmedia Constant Contact (Magento 2) (SKU tm-constant-contact)

This extension connects Magento 2 to Constant Contact using the Constant Contact API v3. Customers and newsletter subscribers are pushed to your Constant Contact account through a queued sync so that list membership stays current without blocking storefront or admin actions. Authentication uses OAuth.

• Syncs Magento customers and newsletter subscribers to Constant Contact via API v3.
• OAuth-based connection with client ID and client secret.
• Queued sync so contact updates do not block checkout or admin saves.
• Sync logs for troubleshooting failed or pending contact pushes.
• Configurable logging level.

• Magento 2.4.x (Open Source or Adobe Commerce).
• PHP: ^8.1 (as declared by the published package).
• A current Toweringmedia license and Composer credentials for https://composer.toweringmedia.com/.
• A Constant Contact account with API access, and an application registered there to obtain the OAuth client ID and client secret.

Install and validate in a staging environment before production rollout.

Toweringmedia packages are served from the licensed Composer repository https://composer.toweringmedia.com/. If Composer reports that the package could not be found, your credentials are missing or the license does not cover this package yet. Retrieve your keys from My Account on toweringmedia.com, or contact support@toweringmedia.com.

General installation notes that apply to every Toweringmedia extension are in the installation guide.

• Stores > Configuration > Towering Media > Constant Contact (Towering Media) (config section toweringmedia_constantcontact).
• Groups: general (enable, logging level) and oauth (client ID, client secret).
• Admin screens: Marketing > Constant Contact > Sync Queue, Sync Logs, and Configuration.

1. Register an application in Constant Contact and copy the client ID and client secret into the OAuth group, then complete the OAuth authorization.
2. Enable the module, then watch Marketing > Constant Contact > Sync Queue to confirm contacts are being picked up.
3. Check Sync Logs if contacts stay queued or report an error.

• bin/magento module:status shows the module(s) as enabled.
• Extension configuration saves without errors in Admin.
• The admin screens listed above are reachable and load without error.
• Expected storefront/admin behavior is present after a cache flush.
• No critical PHP/JS errors appear in var/log/ during the primary test flow.

• Composer cannot find the package: confirm the https://composer.toweringmedia.com/ repository and your credentials are present in auth.json, and that your license covers this package.
• Feature not visible: verify module status, flush cache, and redeploy static content.
• Admin setting not applying: clear cache and confirm the config scope (default / website / store view).
• Unexpected behavior: retest with only the required related modules enabled.
