The Dropbox API servers will be updated with certificates issued from a new root starting on or after January 1, 2026.
Some of the official Dropbox SDKs implemented certificate pinning based on a list of root certificates included in the SDKs. These certificates will stop working in many web browsers and devices in 2026, so Dropbox needs to change which root is used to issue its server certificates. Apps using these SDKs need to be updated to the latest versions of the Dropbox SDKs to ensure uninterrupted access to the API.
The versions listed below have been updated to maintain compatibility with the Dropbox API servers going forward:
- Java SDK v7.0.0 or greater
- .NET SDK v7.0.0 or greater
- Note that apps using older versions of the .NET SDK are only affected if they call DropboxCertHelper.InitializeCertPinning().
- Python SDK v12.0.2 or greater
If you are using any of the above SDKs, please update your app(s) to use the latest versions of these SDKs as soon as possible to ensure continued access to the Dropbox API.
The following official Dropbox SDKs are not affected:
Third party libraries may or may not be affected by these changes. Please consult their documentation for further information.
