What's in the Update

The Files API lets you upload a file once and reuse the resulting file_id across multiple requests. Today's update adds three changes.

  • expires_in_seconds — an option to set an expiration time, in seconds, for uploaded files.
  • Rate limits are now 5x higher, allowing up to 500 requests per minute (RPM).
  • Organizations can now store up to 1 TB of files.

What This Means for Developers

The expires_in_seconds option gives developers direct control over a file's lifecycle, making it easier to auto-expire temporary files instead of managing deletion manually. The higher rate limit and expanded storage capacity give applications that rely heavily on the Files API more throughput and storage headroom.
