After logging into the transaction system, go to the "Business Role Application" menu, and select the roles to apply for as needed (for product listing, apply for the "Supplier Role"). Multiple roles can be selected. Role and permission explanation:

1. Go to the "Product Registration List" menu.

2. Enter the basic product information, and if it is a data API product, API interface call information must be entered.

3. After entering the interface information, it must undergo online testing to ensure the interface can connect properly.
(If the interface cannot pass the test, contact customer service for assistance.)

4. After confirming the product information, it can be submitted for review by the trading center. You will receive a notification via SMS once the review is completed.

Once the product is approved, it must be publicly disclosed for 3 days on the platform. The publicized products can be viewed in the product registration platform.
If objections are raised during the public disclosure and the product is found problematic upon review, it will be withdrawn and not released. Products that complete the public disclosure will receive a Product Registration Certificate.

Once the product registration is complete, you can package and list the product. Go to the "Product List" menu to add the product and supplement product information (only products that have been fully registered can be selected). Once the product is submitted, the trading center will review it and notify you of the review results via SMS.

After the product review is approved, click the [List] button to list the product.
When listing the product, you need to choose the location: Mall (Data Product Mall), visible to all users; or Zone (Data Product Zone), usually for data products related to specific industries, attributes, or application scenarios. Zone listings require approval from zone operators. Products can be listed in both the Mall and Zone simultaneously and can be listed in multiple zones at the same time.
