# Retrieve order cancellations summary

Call this endpoint to retrieve the cancellation summary including cumulative cancellation rate, impacted orders, and trend indicators for a defined report duration (14 days, 30 days, 60 days, 90 days). You can can use this endpoint to understand the percentage of their orders that are canceled. Walmart Marketplace requires sellers to keep [the cancel rate within the specified standard](https://marketplacelearn.walmart.com/guides/Policies%3E%3E%20&%20standards/Performance/Seller-performance-standards#additional-guidelines) to ensure a positive customer experience. For more details about performance standards, refer to [Seller Performance Standards](https://marketplacelearn.walmart.com/guides/Policies%3E%3E%20&%20standards/Performance/Seller-performance-standards#additional-guidelines).

This endpoint uses metrics like cumulative trends, shipping methods, and number of orders affected by invalid tracking information to calculate the percentage of orders that are canceled.

> This page describes an example using only the required parameters and inputs to retrieve valid order cancellations summary. For a full list of customization options and additional capabilities, refer to the [Marketplace Insights API Reference](/reference/getcancel).

The `cumulativeRateTrend` response parameter uses the statuses in the table below to explain if a trend is a positive or negative change. Trend indicates how this metric has changed compared to the previous report duration ending the day before.
