This extension provides additional mail merge tokens for CiviCRM that pull in CMS content.
Current Usage: 38
This extension provides a generic way creating a message queue. This message queue could then be used
by other systems to retrieve changes from CiviCRM.
For example we can have a change message queue for submitting changes to an Outlook 365 address book. Every time a name of
a contact or its e-mail address is changed. A message is added to queue. Outlook 365 can then read message by message to process the
changes.
For developers it good to know that the queue used could be extended so that for example you can push the messages to RabbitMQ.
(RabbitMQ is an implementation of a message queue).
By default this extension comes with a CiviCRM Database Queue. This queue could be read with the API ChangeMessageQueue.get

This extension provides a lot of additional features to CiviCRM's events. In particular, you will be able to configure events in CiviCRM, display/use that information in other remote systems and submit registrations for those events back to CiviCRM.

The general idea is that your organization's staff can do all relevant event configurations in CiviCRM. CiviCRM will then make this information available via its REST API. The extension's API also has built in logic and actions to receive and update registrations.

Any external system can interact with the API and display event calendars, detailed event information, registration forms etc. (this could be a remote system or the CMS your CiviCRM runs on) and also submit information entered by your constituents back to CiviCRM.

All of this requires that you have or set up an external system to act as a frontend for your event listings, registration forms etc. In case you would like to build your system based on Drupal 8 you will most likely want to have a look and/or use the CiviRemote Drupal module which includes a lot of pre-built features (https://github.com/systopia/civiremote).

Note that this extension may be used alongside regular CiviCRM event registrations - you can choose whether you would like to use the remote features or not for each event.
