It's possible to trigger the sending of a pre-defined e-mail template via API. This would be useful for semi-permanent events to trigger finisher e-mails without keeping InstantPush open, since an exporter will remain running if keep timing active is enabled. 

This is currently only possible for e-mails or web service calls, SMS requires additional security authentication which is not possible in this method. 

The e-mail template will be completed at the time the API call is sent. 

To send an e-mail template create a custom API using:

emailtemplates/send?

There are some additional parameters which then need to be appended here, parameters can either be used in the API details in the API setup if they should apply to all API calls, or can be appended to the end of the API url in the API call, when appending to the API url then append "?" first before the parameters. 

&name=

Defines the name of the template which should be sent

&filter=

Used to filter which participants should be sent the template, allows any standard filter to be applied to the list, remember to use percent encoding for any special characters in the string, multiple filters can be joined using AND.
