Install Simple Signature
How to do it in Simple Signature, one step at a time.
Last updated 9 Oct 2026
Install into a sandbox first. When the whole guide works there, come back and install into production.
Open the Simple Signature listing on the AppExchange. Click Get It Now.
Go to Simple Signature on the AppExchange. Sign in when the AppExchange asks. It shows a Trailblazer sign-in or a Salesforce login page. A Trailblazer account is the free login for Trailhead and the AppExchange. If the AppExchange lists your orgs and your org is not there, link it to your Trailblazer account first. The top of the site now reads AgentExchange. It is the same marketplace.
Pick your sandbox as the place to install.
A window asks Where do you want to install this package?. Under Connected Salesforce Accounts, pick the login of your sandbox. Then click the install button.
If the window offers only Install in Production, click Cancel. Open the Simple Signature change log and click Install in a sandbox. Sign in to your sandbox, and go on at step 5.
Later, when the whole guide works in the sandbox, repeat these steps and install in production.
If a terms box shows, tick it. Then click Confirm and Install.
Some installs show the box I have read and agree to the terms and conditions. If yours does not, go to the next step.
Sign in to the org, if Salesforce asks.
Salesforce opens the install page. Its title starts with Install Simple Signature, and it shows the version number. When Simple Signature is already in the org, the page offers Upgrade in place of Install.
Approve third-party access. Then click Continue.
A window named Approve Third-Party Access lists the web sites that Simple Signature calls, for features such as QR codes and Google Docs:
- CSP Trusted Site:
https://api.qrserver.com - Websites:
api.addressverificationapp.com,docs.googleapis.com,script.googleapis.comandwww.googleapis.com

Tick Yes, grant access to these third-party web sites. Click Continue.
When the install takes a while, Salesforce says it will email you when it finishes. Installed Packages then lists the app as ß Simple Signature.
- CSP Trusted Site:
