You may get an email from Salesforce informing you that your self-signed certificate has expired.

If that is the case, you can follow the steps below to renew your certificate. We recommend doing this after hours.

1. From the setup menu, type "Certificate" into the Quick Find bar and click Certificate and Key Management in the dropdown menu.
2. Click Delete for SDocsCert.
3. Click Create Self-Signed Certificate.
4. Set Label to SDocsCert.
5. Set Unique Name to SDocsCert.
6. Click Save.
7. Click Download Certificate.

The next steps are different in Salesforce Classic and Salesforce Lightning.

For Classic:

1. From the setup menu, type "Apps" into the Quick Find bar, then click Apps (under Build > Create).
2. Scroll down to the Connected Apps section, find "Sdocs Connected Apps," and click the Edit link next to it.
3. Scroll down to Use digital signatures.
4. Click Choose File and select the previously downloaded certificate.
5. Click Save.
6. It may take several minutes for the new certificate to take effect.
7. Confirm that everything is working (test SDJobs with Mass Merge).
