Triggers & nodes

• submission.created — fires once per new response.
• submission.updated — fires when a submission is edited.
• schedule — cron-like scheduled runs.
• webhook — external service posts JSON to a unique URL.

• email — transactional email via SMTP or SES.
• slack — post to a channel or DM.
• http — call an arbitrary HTTP endpoint.
• approval — block until a reviewer decides.
• branch — conditional routing based on data.
• delay — wait N seconds/minutes/hours/days.
• esign — request a signed document.
• google_sheets_append — append a row to a Google Sheet using a connected Google account (per-user OAuth, drive.file + spreadsheets scopes only).
• google_drive_upload — upload an uploaded file to a Google Drive folder (drive.file scope only).

Google nodes require a one-time OAuth connection at /api/integrations/google/connect?bundle=sheets (or bundle=drive). Tokens are AES-GCM-encrypted at rest and never leave the server. Sheet writes use valueInputOption=RAW so respondent text is never interpreted as a formula.

On self-hosted deployments you can register your own nodes by implementing the WorkflowNode interface and dropping it into the nodes/ directory.
