Store listing

Name: Chlabs Amazon → La Poste CN23

Summary: Create and email La Poste CN23 codes from eligible Amazon Seller Central orders.

Category: Productivity

Language: English

Detailed description:

Chlabs Amazon → La Poste CN23 adds a focused customs workflow to Amazon Seller Central order pages.

For merchant-fulfilled orders outside the EU customs territory, it extracts the visible delivery and item details. Every declaration opens a review screen where its description, HS code, origin, quantity, weight, and declared value in EUR remain editable. After explicit confirmation, La Poste creates a withdrawal code and can email it directly to the seller.

Highlights:

  • Button appears only for destinations that normally require an export customs declaration.
  • Supports special EU customs territories as well as non-EU countries.
  • Configurable declared value for every individual item.
  • Mandatory review and confirmation before every real declaration.
  • Persistent PDF download and controlled regeneration when a declaration is invalid.
  • No backend, analytics, advertising, remote code, or third-party shipping intermediary.
  • Amazon and La Poste credentials remain in their signed-in browser sessions.

Customs classifications and declared data must be verified by the seller. The extension does not provide legal or customs advice.

Privacy

Single purpose:

Create and email La Poste CN23 withdrawal codes from eligible Amazon Seller Central merchant-fulfilled orders and record the resulting code locally.

Storage justification:

Stores user defaults, seller-verified item metadata, reviewed declaration snapshots, returned barcode PNGs, and generated withdrawal codes locally so PDFs can be downloaded again.

Host permission justification:

Access to sellercentral.amazon.fr reads the visible signed-in order page and displays the CN23 button and editable preview only on eligible non-EU-customs destinations. Access to cn23.laposte.fr submits the reviewed declaration to La Poste, requests code delivery to the configured seller email, and provides the visible official form as a fallback.

Remote code: No, I am not using remote code. All executable JavaScript is included in the extension package.

Data categories to select:

  • Personally identifiable information
  • Personal communications
  • Location
  • Website content

Reviewer test instructions

  1. Install the extension and open a signed-in Amazon Seller Central France merchant-fulfilled order detail page.
  2. For a non-EU customs destination, verify that Create La Poste CN23 appears. For an ordinary EU destination, verify that it does not appear.
  3. Open the preview. Verify the recipient and edit each item's description, HS code, origin, quantity, weight, and declared EUR value.
  4. Configure a test sender and email in extension options and accept the reviewed-submission consent.
  5. Submit the reviewed preview. Verify that La Poste returns a withdrawal code, the extension displays it, and it is associated locally with the Amazon order.
  6. Reopen the completed order action and verify that its PDF can be downloaded again.
  7. Choose Regenerate declaration, verify the complete preview reopens, and confirm the previous PDF remains downloadable.
  8. If the private endpoint is unavailable, verify that the guided official La Poste form opens as a fallback.

The extension has no Chlabs account or backend. Review requires reviewer-controlled Amazon Seller Central and La Poste sessions; no credentials are embedded in the package.
