## Assay Results creation API limit changes

To protect the stability and performance of the Assay Results creation API, we've introduced a new [throughput rate limit](/docs/rate-limiting#throughput-rate-limits) on the number of requests that can be processed within a time period. The `/assay-results` creation endpoint is now limited to **10,000** requests per hour. These changes are **effective immediately.**

### What’s changing?

Previously, the [POST /assay-results](https://benchling.com/api/reference#/Assay%20Results/createAssayResults) endpoint was subject to overly-permissive limits which resulted in performance and stability issues during periods of high traffic. This endpoint now has a [throughput rate limit](/docs/rate-limiting#throughput-rate-limits) of **10,000** requests per hour to better protect the stability of Benchling's systems.

> **Isn't this a breaking change?**

> Due to the impact on the performance and stability of Benchling's systems, these limits are being implemented on an expedited timeframe. For more information, check out Benchling's [Stability Guidelines](/docs/stability)

To avoid disruption, it's important to make sure all integrations are limiting the number of requests within a 1-hour time window. Additionally, implementing proper rate limit handling (e.g. [exponential backoff](/docs/rate-limiting#handling-rate-limits)) will help ensure that integrations operate gracefully within Benchling's rate limits.

Integrations may also use the [POST /assay-results:bulk-create](https://benchling.com/api/reference#/Assay%20Results/bulkCreateAssayResults) endpoint, which allows creation of more results within a single request.

### When is this happening?

These changes are **effective immediately.**
