Product guide
Zeto Sign
Create a hosted signing link from a Google Form, collect a drawn signature, and store the signature URL with the completed response.
Set up a signing link
Zeto Sign starts from the Google Form you already manage. Sync the form, share the hosted signing link, and let Zetomation submit completed responses back into the original form workflow.
2
Launch Zeto Sign
Use the Google Forms add-ons menu to open Zeto Sign. The sidebar reads the current form schema and prepares it for a hosted signing page.
3
Sync the form
Click Sync Form to send the form structure and required metadata to Zetomation. Zeto Sign returns a hosted signing link for that form.
4
Open the native Google Form once
After syncing, open the original Google Form response URL once. This helps Google activate the form and linked Sheet response connection before signers submit.
5
Share the signing link
Use Take Signatures to copy or open the hosted Zeto Sign URL. Send that link to the people who need to complete and sign the form.
6
Review responses
Use See Responses in the add-on to review hosted submissions and signature URLs stored by Zetomation.
Data flow
When a form owner syncs a form, the Zeto Sign add-on reads the current form schema, form ID, and owner email. This lets Zetomation render a mirrored hosted signing page for that specific form.
When a signer opens the hosted link, the signer submits the answers and drawn signature directly to Zetomation. The signature image is stored by Zetomation and represented as a public signature URL.
After the hosted submission is stored, Zetomation attempts to post the standard answers and signature URL back to the original Google Form so the connected Google Sheet can receive a normal response row.
Internal signature field
Zeto Sign maintains an internal Google Forms question named Zeto Signature Link. The hosted signing page hides this question from signers, then uses it during proxy submission so the linked Sheet can store the final signature URL.
OAuth scopes used by Zeto Sign
Zeto Sign uses a narrow Google Forms add-on permission set for the current form, external requests, add-on UI, and owner email context.
| Scope | Purpose |
|---|---|
| https://www.googleapis.com/auth/forms.currentonly | Read and update only the Google Form currently opened by the form owner. |
| https://www.googleapis.com/auth/script.external_request | Send the synced form schema and metadata to Zetomation and retrieve hosted response information. |
| https://www.googleapis.com/auth/script.container.ui | Display the Zeto Sign sidebar and response dialogs inside Google Forms. |
| https://www.googleapis.com/auth/userinfo.email | Associate the synced form with the form owner email for support and ownership context. |
For the full privacy disclosure, see the Zetomation Privacy Policy.
Troubleshooting
The linked Google Sheet does not show a new row
Open the native Google Form once after syncing, confirm the form has a linked response sheet, then submit through the Zeto Sign hosted link again. Google account permissions, form settings, and Google Forms availability can affect whether the proxy response is accepted.
The signature URL column is missing
Run Sync Form again and do not delete the internal Zeto Signature Link question from the Google Form. Zeto Sign uses that hidden/internal field to write the signature image URL into the response row.
The hosted signing page does not match recent form edits
Sync the form again after changing questions, sections, or required fields. The hosted page renders from the latest schema stored by Zetomation.
The OAuth window says the app is under review
During Google verification, only approved testers or verified users may be able to authorize the add-on. The public Zetomation homepage and product pages identify the app name as Zeto Sign for review consistency.
