# Product Data Access (Closed Beta)
# Product Data Application Scenarios
Product data is currently applied to WeChat scan object function、Mini Program product search function and Scan barcode Three functions. These functions can be a good way to meet the needs of WeChat users for information access to goods, but also for the business mini program to bring exposure traffic and build user brand awareness opportunities.

# Product data access
At present, WeChat has climbed some product details pages, and has carried out a certain analysis and understanding of the product information on the page. Merchant mini programs can cooperate with access to product data to help WeChat better discover more and richer product information and improve the exposure opportunities of goods.
Successful access requires the following three steps:
# Step 1: OpenReptile switch
Ensure that the crawler switch is on to ensure that the content of the mini program page has the opportunity to be included by WeChat. Crawler switch is set on WeChat Official Platform, can refer to the following diagram.
# Step 2: PushPage Path
Actively push the page path of the product details page to the WeChat background through the interface, to ensure that the push page is found in time by the WeChat crawler and gain exposure opportunities. Specific Reference:Mini Program search.submitPages Interface Documentation
# Step 3: AccessData Update Protocol
Access to the data update protocol, can support WeChat real-time access to the price of goods, shelf status and other latest information, to avoid inaccurate information and affect the exposure effect of goods.

After completing the above three steps, the product details page of the merchant's Mini Program will be included, and the exposure opportunity will be obtained in the "scan and scan identification function," "Mini Program product search function" and "scan bar code."
In addition, we recommend that the merchant Mini Program can also continue to mark up the page structured content and optimize the page structure:
I. MarkingPage Structured Content
By tagging the structured content of the page, it helps the WeChat crawler to better understand the page information, improve the accuracy of the page recall ranking and the exposure conversion rate.
