To ensure the proper functioning of the Amazon Marketplace module, it is essential to correctly configure your scheduled tasks (cronjobs).

Note: do not forget to configure the cronjobs parameters

⚠️ Important Recommendation

We no longer recommend using the "PrestaShop Cronjobs" module available on Addons or GitHub. This module is no longer maintained or supported by PrestaShop, and may cause unexpected issues.

We recommend configuring your scheduled tasks directly on your server using crontab, or by using a reliable external service such as:

https://cron-job.org
The scheduling system provided by your hosting provider (if available)

Note – Amazon Marketplace Plus (SaaS)

If you are using the Amazon Marketplace Plus (SaaS) version, scheduled tasks are already configured on our servers.

👉 You only need to activate them from the module's "Scheduled tasks" tab.

List of Key Scheduled Tasks

Each Amazon marketplace configured in the module must have its own scheduled tasks.

Report Listing Inventory – URL to fetch & save data report listing inventory.

It records which offers already exist in your Amazon account.

This helps the module decide:

If the offer already exists → the module simply updates it (price/stock).
If the offer does not exist and you have enabled the Matching option → the module tries to match it to an Amazon product using its EAN/UPC.
If a match is found → Amazon adds the offer to your account without creating a new product.

If the scheduled task "Report Listing Inventory" is not executed, the module cannot synchronize offers. You will then see this error: This SKU has not been listed on Amazon (From version 5.4.08).

⚠️ Important distinction: if matching is applied to an offer that already exists, Amazon may overwrite some product details (e.g. color, size). 👉 This cron is essential to prevent such issues: it allows the module to know whether an offer already exists and to choose the correct action (update vs matching).

1 task per marketplace
Recommended frequency: every 4 hours

Synchronization – URL to sync offers

Updates stock and price on Amazon.

1 task per marketplace
Recommended frequency: every hour

Orders – URL to import orders

Imports new Amazon orders into PrestaShop.

1 task for unified Europe, or 1 task per country outside Europe
Recommended frequency: every hour

⚠️ Warning: this process may be blocked if some products are out of stock. Check the pending order list regularly.

Orders – URL to send status

Updates order statuses (e.g., shipped) on Amazon.

1 task for unified Europe, or 1 task per country outside Europe
Recommended frequency: every 4 hours

Testing a Scheduled Task

To verify that a script is working correctly:

Copy the URL provided by the module in the Scheduled Tasks tab
Paste the URL into your web browser’s address bar
Check that no error appears

Example:

Cron URL Example

If a message such as “Error” appears, it means the script failed to execute properly.

Best Practices

Only a qualified person (webmaster, IT provider, etc.) should configure these cronjobs. This type of setup is not covered by module support, as it depends on your server or third-party cron service.

Set up cronjobs only after the module is fully functional and tested. It is the final step of the setup process.

Follow the recommended execution intervals. Calling these scripts too frequently can disrupt the normal operation of the module, and Amazon applies request quotas (e.g., max requests per hour).
