An example to a workflow idea, could be to send an automatic email with the users certificate, after the user completes an learning activity. This could help the user to retrieve his/hers certificate quickly, and get the felling of completion.
The workflow idea is illustrated as a flowchart below.
The different symbols represent the parts of the flowchart.
Workflow on: Activity A
Event type: Enrollment Completed
Action type: Send Message(Enrollment Completed)
Prior to setting up the workflow, we need to enable (and maybe customise) the certificate. This can be done by enabling certificate in general in Admin > Configuration > Certificates > Enable Certificate. You can customise the layout of the certificate to your needs in Admin > Configuration > Certificates by the use of tokens and HTML.
The email template used here (Enrollment Completed) will by default contain a link to the learners certificate. You can of course make another (or customise) a email template containing a link to the learners certificate (using the token %%CertificateLink%%) and then use that email template in the action (Send message).
Read the "How to create a workflow" article if needed and follow the instructions where you can fill in the necessary information. An example to creating the workflow can be seen below.
