Incident Report

Summary AI Generated

Blend's external API experienced elevated error rates for approximately 3 hours, impacting a subset of Blend-managed integration connectors and causing failures in loan data exports, document transfers, LOS event delivery, and other integration-driven workflows. The issue was traced to a misconfigured configuration change that affected only certain connectors, while the core Blend application and most integrations remained fully operational throughout. Blend's engineering team reverted the configuration change to restore normal connector processing, and any impacted events are being identified and retried.

We're investigating elevated error rates on Blend's external API (api.blendlabs.com). Some API requests from partner and vendor integrations are failing or completing only after retries and delays. This may impact integration-driven workflows, including document generation and loan exports to your LOS. The core Blend application is operating normally. Our engineering team is actively investigating and we'll post an update as soon as we have more information.

We identified and reverted a configuration change that was causing request failures for a subset of Blend-managed integration connectors. All connectors are now processing normally, and core Blend application functionality was unaffected throughout. We are reviewing any events that were impacted during this window and will retry those as needed. If you have questions about specific transactions, please reach out to your Blend contact.

We've identified the cause of errors affecting a subset of Blend-managed integration connectors. Affected customers may experience failures in loan data exports, document transfer between Blend and the LOS, and inbound LOS event delivery that updates records in Blend.
Core Blend application functionality and the majority of integrations remain unaffected. Our engineering team is actively working on remediation.

We've narrowed the issue to a subset of Blend-managed integration connectors. Affected customers may experience failures in loan imports, document generation, disclosure delivery, and closing workflows that depend on these integrations. Most integrations and all core Blend application functionality are operating normally.
Our engineering team is working to mitigate the failures and restore the service.
