Upcoming TLS Certificate Rotation for the Blend Public API

On Tuesday, September 9, 2025, at 6:00 PM PDT, Blend will rotate the public TLS certificate for the Blend Public API (api.blend.com and api.blendlabs.com). This rotation will occur during our standard production release window. The current certificate will expire on September 15, 2025.

Who is impacted?

This change only affects customers who authenticate to the Blend Public API using mutual TLS (mTLS). Customers not using mTLS will experience no impact and require no action. Blend has already contacted all impacted customers to assist with this transition.

Questions?

If you have questions or need a copy of the new public TLS certificate chain, please contact Blend Support or your Blend Customer Success Manager.
