Incident History

October 2026
Sign Integration Authentication Issues
minor Observed active window 2h 2m

View incident details and source

Started:

API & Document Generation Documents
monitoring
A fix has been deployed to prevent Formstack Sign connections from losing authentication unexpectedly, and we are monitoring the results. We are also working to automatically restore authentication for previously affected connections. Customers who need to resume processing immediately may manually reauthenticate their Formstack Sign connection. We will provide another update once the restoration process is complete.
identified
We have identified an issue causing some Formstack Sign integrations, including Documents-to-Sign deliveries, to lose authentication unexpectedly. Affected deliveries may fail with an authentication error, even if the connection was recently reauthenticated. Our Engineering team is actively working to deploy a permanent fix. We will provide another update as soon as the fix has been released.
September 2026
Delayed Documents Deliveries After Sign Completion
minor Observed active window 6h 16m

View incident details and source

Started:

API & Document Generation
monitoring
A fix has been deployed that has solved these delayed deliveries. The issue was that Formstack Sign was not sending the Formstack Documents product the notification that document was completely signed (i.e.: Finalized). We are now working on a script in Formstack Sign to send all those notifications back to Documents, so delayed deliveries should start processing soon.
identified
We have narrowed this issue down to Delayed Deliveries in Documents, when a delivery to Formstack Sign is included. If a document is sent to Sign and it is subsequently completed, Documents is not getting the file back and therefore not delivering it to the next step, such as Salesforce, Sharepoint, etc.
identified
The issue has been identified and a fix is being implemented.
investigating
We are investigating an issue affecting some Formstack Documents workflows that use Formstack Sign. Although signing completes successfully, subsequent deliveries including Salesforce, SharePoint, and webhooks may not be released and may remain in a delayed status. Our team is actively working to resolve the issue. We will provide additional updates as they become available.
