Access Tokens — Comparison Guide
Survanta offers three access-token scopes: SingleSurvey, TenantActiveSurveys, and ResponseViewer. Guest use does not require an account; an eligible signed-in tenant user can also submit through public answering flows with attribution when a JWT is supplied.
The Three Types at a Glance
| Type | Main purpose | Survey scope | Can submit? | Can view results? |
|---|---|---|---|---|
| Public Survey Link | Fill one survey | One survey | Yes | No |
| Portal Token | Choose and fill from eligible surveys | Tenant-wide (all active published surveys) | Yes | No |
| Viewer Token | Read permitted results | All permitted surveys, or one specific survey | No | Yes |
How to Choose
Choose a Public Survey Link when you want people to answer one specific survey. It is the simplest option: one link opens one survey, and the visitor submits a response. Use it for a single questionnaire sent to an external audience.
Choose a Portal Token when you want people to pick from several surveys through one shared entry point. The portal lists all of your tenant's currently active, published surveys, and the visitor chooses which to answer. Use it when a group needs access to whatever surveys you are currently running, without sharing a separate link for each.
Choose a Viewer Token when you want someone to read results rather than answer surveys. It is read-only, so the visitor can never submit or edit anything. You decide whether it covers all permitted surveys or one specific survey, and which viewing capabilities are enabled. Use it to give an external client or reviewer a controlled window into results.
Single-survey and portal expiry is optional. Viewer expiry is required and cannot exceed ViewerTokenMaxDays; when export is enabled, the shorter ViewerExportMaxDays bound applies. Creation is separately limited by MaxPublicSurveyLinks, MaxPortalTokens, and MaxViewerTokens.
