Multiple Signatures - Signature View link is protected

Signature View links are password protected by default for maximum security.

For two hours after signing, the link is "open", where other add-ons and the respondent may view and take any action as needed. After that time the link becomes protected. Protected links can be opened only by the Owner or any current Collaborator of the Form.


Editors may click the "View" button. The first time, they're asked to allow "Signature log-in" access to their account. This only retrieves "Basic profile information", which is your email address.

We use this to check against the list of Editors in the Form to decide if you can continue.

If you get stuck in a loop at this stage, please see our notes on "Multiple accounts"

Changing the security setting

This can be done from the Dashboard.

iOS - camera button not activating camera

  1. Click "AA" at the top left

  2. Open Website Settings

  3. Click the Camera area - this will probably say "Deny" currently

  4. Set this to "Ask" or "Allow", then click Done

"View link" doesn't show all questions and answers

If you review your Response Sheet, are the missing questions/answers in columns after/to the right side of the "Signature" column (which contains links)?

The "signature view" link will only display questions - specifically columns - to the left of the signature image; the case usually being that the signatory has only seen those preceding questions, so can only sign for them.

Google inserts new columns in the Response Sheet when questions are added. If the questions are moved in the Form, Google doesn't update the column position in the Spreadsheet to match unfortunately. It's likely signing was turned on, then your missing questions were added afterwards.

If the above column arrangement looks true, you should be able to simply move the "Signature" column so it's the last one in the Spreadsheet (excluding blanks).

Signatures already received will say "Couldn't verify...", but will show everything. Signatures received after moving the column will show all of the preceding questions and answers also with the verification in place.

Green button is missing

The green button should appear on the Form when it's visited via a link the add-on provides.

This link is either emailed directly to the recipient (for Single Signatures), or is copied to the Form Owner's clipboard so they can paste in an email or as a link on a website etc. It can be retrieved at any time by the Form owner from the "See pending" area of the add-on.

The standard Form "Send" menu options unfortunately won't load any signing features or green buttons.

If you're using a link from the add-on and it's still not loading the green button, please forward that to us so we can check why.

Please also let us know what internet browser you are using so we can check compatibility.

Form requires log-in

Most browsers unfortunately won't allow the Signature add-on to work when the Form requires the user to be logged-in.

These features usually are:

  • File Upload questions

  • "Restrict to users in ... and its trusted organisations"

  • "Limit to 1 response"

As the Form's owner, please remove these settings/items and re-try activating the Form for signature collection.

Apple Content Restriction - Allow/Whitelist

If you use Apple's systems to limit web activity, you can Allow these sites to work with Multiple signatures:

Our main signing link (excluding the parts that might change, which means any Signing activated Form could be reached):

Google Forms (all Forms - alternatively specify your own Forms individually):

Google user-created content (we can't get more specific than this unfortunately as these seem to change every other visit):

No Form access / We don't have access to the Form or Sheet

The add-on adds a "bot" account as an editor on the Form (and Sheet for Multiple Signatures) so it can insert additional information.

Occasionally this access is removed by a user or policy etc., and in rare case it isn't applied correctly! We encourage Form owners to use the "Test" button that's presented straight after signing is activated.

If access is missing, you can resolve it by adding our bot account "" as a Contributor in the Form, and as an Editor in the Response Sheet.

The link will immediately start working again.

Accounts error / Not loading / The add-on is receiving mixed messages

​When the add-on is used, Google may inadvertently say one account is using it rather than the other. This can easily lead to errors so we prevent you from continuing.

T​here are three solutions:

  • Use a Chrome Profile with just one account logged-in (this is our preferred method)


  • Open a new Private or Incognito browsing window and visit You'll be asked to log in before you can continue to your Form


  • Log out of Google, then log back in with just one account

Response Sheet missing

"Response Sheet missing" will appear when the Form doesn't have a Google Spreadsheet attached.

A standard Google feature of Forms is to attach a Google Spreadsheet to store responses. We use this Sheet also as the actual signature data location so we don't store any of your users' personal information.

As the owner of the Form, open the "Responses" tab, then click the green Google Sheets icon to attach a Response Sheet.

Malformed UTF-8 content / Link error

If you receive this error, the link you are using has been truncated. This occasionally happens when emailed; email programs might change the link's format.

If you are the Form's owner, please always "beautify" the link in an email by pressing Ctrl+k. This will also allow you to make it appear better looking.

You can get the link again at any time from the "See pending" area of the add-on.Please re-send the link to your users so they have the correct version.

If you are not the Form's owner, please contact them and advise them that they need to re-send you the link, or instruct them to read this help section.

No signatures available

The error message " ... (the account holder of this Form's signatures) has no signatures available." refers to the current balance of signature tokens in the Form owner's account.

If you are not the Form owner, please ask them to increase their balance or visit this help page.

If you are the Form owner, 10 signatures are included when installing the add-on so you can get started. Each month you're topped-up to 3 also.

If you need to collect more signatures than these limits, you can purchase them within the add-on under "Get more signatures", or on our bulk-buy page for a discounted rate (this is also linked within the "Get more signatures" tab).

We use simple sales to keep the add-on funded. We don't show advertisements or sell any information.

Multiple Signatures Form with hundreds of responses has stopped working

Occasionally Sheets stop responding to external API's like ours. We usually see this starting to occur at around 500 responses.

When your Form approaches 500 signatures, we recommend switching out the Response Sheet for a new one.

There are two options:

  1. Create a new Form and Response Sheet

(This will mean a new signing link to give to people)


2. Unlink the existing Response Sheet and link a new one

To do option 2:

In your Google Form, visit the Responses area and click the green Sheets icon, and choose to Unlink.

Then delete all responses from the Form itself - responses already received are still stored in the existing Google Spreadsheet which you'll keep.

Then click the green Sheets icon again and create a new Response Sheet.

This lets you continue as before, using the same Form and signing link.

Keep the old Response Sheet - the add-on should be able to access it again after a little time. The contents can also be copied to a new Sheet and viewed.

(You'll visit the "Dashboard" from any View link, or the "See pending" area of the add-on, and paste the old Sheet's URL to view the contents) refused to connect

  • Log out of Google

  • Log back in with just the one account you'll be using with Forms

This is a well known issue in the Google add-ons community and Google are working on it. It's related to having two or more accounts logged-in at once, and the permissions are being picked up from the wrong one

General permission reset

General errors can be a result of incomplete permissions. The first thing we recommend for nearly every error is as follows

  • Find Signature in the list, and click on it

  • Click Remove Access

  • Now you can re-open your Form

  • Close Signature if open

  • Open Signature, and you'll be prompted to give permission (pictured)

If you aren't prompted for permission, please revisit from the first step

  • Accept the access/permission requests

  • We recommend cancelling and re-creating any Signatures, so they'll have all the right permissions

Multiple Signatures Response Sheet has "Pending"

Pending means one of two things:

  • We've received a signature but couldn't find an appropriate place to put it


  • Your user didn't sign

If it's been more then a day, it's the latter

Click the Pending link - this takes you to a dashboard

You can pick the correct place for any existing signatures we hold, then draft an email template and easily send this to everyone that's missed the signing process. When they do, Pending will change to View Signature

Won't open

Signature isn't an option in the jigsaw-piece menu

The add-on isn't installed, or hasn't loaded

Try refreshing and waiting a moment. If it's still missing, follow the Installing steps

"Start" isn't there, only "Help"

It's installed, but hasn't loaded yet. Wait a moment, then use the jigsaw-piece menu again

Or refresh the page if it's being particularly stubborn

Stuck at "Checking..."

Wait up to a minute - this can take a little longer as we're creating an account for you

If it's been a minute, there may be a problem. Usually the permissions haven't come through completely

We recommend uninstalling, and reinstalling the add-on to get the security prompts to appear. It only takes about 30 seconds

To uninstall, follow the steps at


You'll see that the "Add" button in the marketplace will now say "Uninstall"

When you follow those steps again to reinstall, take note of whether you receive the Google security pop-up, and ensure you accept it

(If you look at the Youtube video in the above link, you'll see the prompts appear about 25 seconds in)

It may pop up when you first try to open the add-on, rather than when it's installed

If you don't get any security prompt, it might be blocked by your browser. We recommend Chrome, but any current browser should be fine. Internet Explorer isn't recommended

Problems with signing

No signature

A signatory will see this screen in the following cases

  • The person who requested the signature has since deleted their request; if so, this isn't an error


  • We couldn't automatically pair the signatory with the signature request


Ensure you're using a link that we created

  • Email them for me | the signatory was sent an email from us - this email contains a link - use that

  • I'll contact them myself | the signatory wasn't sent anything directly by us - you were provided a link to copy and send on yourself. You can get this again by opening the add-on, clicking on Pending, and using the controls in that menu. Send that link to your signatory

Access error

A signatory will see this screen if we no longer have access to the Editor's Form. We need access to be able to append the signature to the Form and/or Response Sheet

This is a result of us being removed as Editors/Contributors. Removal is usually a manual process, but if you are the Editor and are coming across this regularly, please check if you have any other apps which might change permissions on your Google files


We provide a note which will pop-up when the Editor opens the add-on. The Editor will need to remove and recreate the signature request which will reapply the necessary access rights

Form isn't accepting signatures

A signatory will see this screen on a Multiple Signature attempt if the Form Editor has 0 signatures remaining

It is also given if a link is used which refers to any form which isn't accepting Multiple Signatures


The Form Editor can obtain more signatures, and signing will automatically continue
