Connection
- This channel is a Mirakl-based channel. Therefore, you connect to it with your Mirakl Connect SSO account. For more information on configuring Mirakl Connect SSO with ChannelEngine, check out the Mirakl-based channels: SSO authorization article.
- If you would like to test the order flow with this plugin, contact the ChannelEngine Support team to configure the connection of your plugin to support testing. For more information on testing orders, check out the article ChannelEngine: how to create test orders.
Invoice uploads
To configure your invoice settings, go to Advanced settings. Then, select one option from the dropdown menu in the Enable invoice uploading field, which contains the following options:
- ChannelEngine invoices - when ChannelEngine receives a shipment, ChannelEngine automatically generates an invoice and attaches it to the shipment before exporting the shipment.
- Merchant invoices (optional) - when ChannelEngine receives a shipment, ChannelEngine exports the shipment – even if there is no invoice attached to it.
- Merchant invoices (required) - when ChannelEngine receives a shipment, ChannelEngine only exports the shipment if an invoice is attached to it. If not, you receive a notification.
- None - when ChannelEngine receives a shipment, ChannelEngine takes no action other than notifying you that no invoice is present.
If you select one of the Merchant invoices options, make sure to upload the invoice to ChannelEngine via the Merchant API or via the web interface. To learn more, check out the article ChannelEngine: upload merchant invoices.
Mappings
Content
All products (required)
The following required attribute is common to all Mirakl-based marketplaces:
-
Export strategy - choose a strategy for exporting product data. You can select from the following export strategies:
- Yes - export all product content to the marketplace, including the EAN (GTIN), category, and other mapped attributes. This option is ideal if you manage both product content and offers through ChannelEngine for the marketplace. Before you set this option, ensure that you map all required attributes.
-
No - do not export product content to the marketplace. Choose this option to keep the product content excluded from exports and only export the offers. This option is ideal if you do not want to export the product content yet, or you want to export only the product offers because the product content already exists on the marketplace.
NB: the default export strategy is Yes, even if the Export strategy attribute is left unmapped.

Carrier
Carrier mapping is not required on Mirakl-based marketplaces. However, with carrier mapping, you can map your carrier to a specific list of carriers maintained by this marketplace. Carrier mapping enables ChannelEngine to automatically send the tracking codes to this marketplace, allowing buyers to eventually track the shipment themselves. If your carrier is missing from the list, please directly contact the marketplace.
Pricing
Working with discounts
These instructions apply to most Mirakl marketplaces. If there are any exceptions on this marketplace, these are noted below.
Pricing v1
- To set up a discount, map the Discount price, Discount start date, and Discount end date attributes. If you want to set a permanent discount, map the Discount end date attribute with a date in the far future instead of leaving it unmapped. Otherwise, the offer is not exported, and errors are shown on the Validation and feedback tab.
- The discounted price is only exported if it is lower than the base price.
- If you do not want to set a bulk discount, leave the Discount quantity threshold attribute unmapped.
- To set a bulk discount, the Discount quantity threshold must be set to a value higher than 1. For example, a value of 2 indicates that the buyer must purchase two or more products at the same time to benefit from the discount.
Pricing v2
- To set up your strikethrough price, map the Strike price attribute to your regular price in Offer mappings.
- Then, indicate the discount period. Map the Discount start date and Discount end date attributes to indicate the start and end dates of your discount.
- If you do not want to set a bulk discount, leave the Discount quantity threshold attribute unmapped.
- If you do not set up a bulk discount, set up your discount price:
- Go to Pricing, Promotions.
- Choose your discount method, e.g.: percentage discount, and configure the start and end dates.
- Select the products to which the discount is applied.
- Keep in mind:
- Your discount price and Strike price cannot have the same value.
- ChannelEngine only sets a discount if your discount price is lower than Strike price.
- If set up correctly, your product displays a discount label and a strikethrough price on the channel.
Listed products
If you have problems with products not appearing on Mirakl-based marketplaces – especially if you are trying to create products, check the Listed products page for more information. Use the Channel status filter or the Validation and feedback tab to view all known errors for specific products.
If you see either of the below statuses, refer to the article ChannelEngine: why is my product listed as 'Product not found' in the inventory report?:
- Product not found in inventory report
- Product not in offer file
Products that ChannelEngine has failed to export are shown as Invalid, e.g.: products with an empty GTIN or that do not yet exist on the marketplace.
Alternatively, download the error report generated by Mirakl. To do so:
- Log onto the Mirakl platform and go to Catalog, Product imports.
- Identify the latest report and click the See details button.
- Download the CSV file Non-integrated products report.
FAQs
How often does each task run on Mirakl-based marketplaces?
By default, Mirakl-based marketplaces follow the schedule below:
| Task | Frequency |
|---|---|
| Export product data to marketplace | every 60 minutes |
| Export product offers to marketplace | every 15 minutes |
| Import product offers from marketplace | every 15 minutes |
| Import orders from marketplace | every 15 minutes |
| Export order shipments to marketplace | every 15 minutes |
| Export returns to marketplace | every 30 minutes |
Can I map attributes on ChannelEngine and on the Mirakl platform?
No. Mapping attributes on the Mirakl marketplace platform interferes with ChannelEngine's content export. Therefore, it is recommended to categorize and map content only on ChannelEngine.
Why am I not receiving feedback on my content and/or offer exports?
Chances are that you are receiving the feedback. However, different types of error reports can take a couple of hours or several days to be generated:
- Offer feedback
- Error reports are mostly generated automatically and are imported quickly.
- Content feedback
- Transformation error report - this is automatically generated, and usually imported within a maximum of one day.
- Conventional error report - this requires a manual review by the Mirakl-based marketplace, and not all do so. It can take several days for this report to be imported.
Note that the previous feedback report is not removed from ChannelEngine until both the latest transformation and the conventional reports have been fully processed by ChannelEngine. If there are no errors to report, no new reports are generated.
