WHY - Use our Calendar Invite platform we call SIS, Simple Invite Service, to build out Killer Applications and workflows. Your customer's calendar client becomes the front end of the headless Calendar invite-sending service. You leverage our built-in workflows for sending Calendar invites across Email and Marketing platforms using our SIS API Kit once our ETL Calendar Invite Engine has processed the event.
HOW - In the first stage, we ETL the Calendar Invite Data from a Calendar Client in 10 seconds using our APIs and Lambdas we call the "ETL Calendar Invite Engine." Stage one is an endpoint for customers to "drop off" the calendar invite using a create@yourdomain.com address you configure. The data is automatically processed when they "Invite you" or "Copy" you to the Calendar Invite using create@yourdomain.com.
WHAT - The calendar invite is now staged in the Simple Invite Service and is ready to be SENT via API calls to the UID Beacon. Our API supports the Building of Landing Pages with Built-in Calendar Invite Boxes for a 1-click calendar invite sending. Also, our API auto-generates RSVP Buttons to be used in MailChimp, Klaviyo, SendGrid, and Convertkit Email Templates for 1-Click sending of Calendar Invites. And thirdly, we support sending Calendar invites to subscribed lists via our APIs. Sometimes referred to “Bulk Calendar Invite Sending”. Your customers can UPDATE and CANCEL the event from the Calendar Client for that specific event generated by create@yourdomain.com. The UID beacon is a part of the service you don't have to "worry about," but essential to understand how your customers can UPDATE and CANCEL the events without logging into an application.
WHERE - The Cloud Formation template is available from us for download and has the Technical Deployment Guide for installing and accessing the APIs and analytics in Quick Sight to build out your own Killer Calendar Invite Applications.
We have 3 Products built into the Simple Invite Service (SIS) that you can build off of for your Killer App. The Calendar Lander for Autogenerating Calendar Landing Pages, the RSVP Button for Email Marketing Vendors and Bulk Calendar Invite Sending to a validated subscription list that you get access to with our SIS API Kit. All the services or channels are tracked independtly in the Reporting Module.
What is SIS? »Simple Invite Service«
SIS is a set of APIs on top AWS Lambda services for building your Killer Apps for sending calendar invites and tracking invitations in a headless event-driven workflow to your favorite Front End Tools.
SIS Service is designed for the builder to "Inject Calendar Invitations', into interfaces, buttons, batch, or stream services using the same Calendar Invite APIS.
We give you your first free Killer App called CalendarSnack in the form of a VUE.JS template. The Calendarsnack App shows how we integrated the API's Landing Pages for 1- Click Calendar Invite Sending or the workflow for Sending Batches of Calendar Invites to an email subscription list or embedding RSVP buttons into Email Marketing Vendors templates for Calendar Invite Sending.
The final point of the calendarsnack integration example is the detailed view of the rich reporting gathered for all your "Domain," and the Individual Calendar Invites.
The Calendar Client is the front end of the headless Simple Invite Service. When your customer drops off the event into the service, we process that Calendar Invitation for you to call via the APIs to send the calendar invite and collect the RSVP data for reporting.
The UID beacon is built into the SIS Lamda service, allowing your customers to update the Calendar Invitation in their calendar client serving as the "Interface" into the messaging service.
Unique IP - Once the Organizers Calendar Client creates the UID to the Simple Invite Service (SIS) , it maintains a relationship so UPDATES or CANCELS can be administrated from the Organizers Calendar Client to the Customers Calendar Client of those who have RSVP'd in a YES or Maybe receipt back to the Simple Invite Service.
Essentially we have designed a Headless Marketing Automation Kit that uses the Calendar Client as the "Operator" of the AWS SIS service.
The headless design is simple but very effective, using the registered UID as the Beacon to communicate as a "web service."
It scales incredibly well for significant community use cases, including designs where you might need to build a data pump that would send millions of Calendar invites based on a consumer database.
Simple Invite Service Workflow
How would you start? Get your domain for RSVP branding. Why? Because this will be the way to deploy the Headless App. Since the backbone of the service is using AWS SES - Simple Email Service, you will be able to manage your brand as an "RSVP" service for the Calendar Invites.
We can help you with this as an option if you need it.
Once you establish your domain, it's as simple as telling your users to use your unique create address off their calendar clients when generating events.
Your users are automatically organized by Organizer email address, so as they use the unique CREATE@YOURDOMAIN.COM they will be automatically tracked in the Dynamo Data Base, and you will have access to the S3 buckets
We will walk you through some of the concepts and components that may give you some ideas in the next couple of screenshots.
To understand more of what’s included in your prebuilt VUE.JS kit. Go get a calendarsnack and walk through the Killer App experience built by our teammate Arnie.
If you become a customer, you will get the VUE templates that have been built to match the SIS API’s workflow specific to the calendarsnack application.
If you want a key to the API Kit, just send me and an email - greghanchin@31events.com and we will send you our beta deployment guide.
We will have a API sandbox up in running by June 2023 with a public key for anyone. For now, we will have to issue out a secured key to our DevOps sandbox with throttle stops on it.

The Upcoming Landing Page is included in the API Kit. It streams all the events for that Calendar Invite Organizer in a simple Landing page that can be shared for easy signups for 1-Click Calendar Invite Sending.
The RSVP Button workflow is for the automation of sending Calendar Invites within an embed API that comes with the SIS API kit. When the RSVP Button code is deployed into the CTA button for MailChimp, Klaviyo, SendGrid or ConverKit and clicked the automated workflow kicks off and an autogenerated Landing page is presented to the user and a calendar invite is sent to be tracked. Every time someone generates a calendarsnack you can request the API for the Button to be displayed in a simple grab and go code to be integrated into the workflow.
Included in the SIS API Kit is the workflow for the Reporting in the VUE.JS templates and a “How to” use AWS QuickSight to explore the data for a single account or all of the account data in the DOMAIN.
All DOMAIN equals all Unique Calendar Invite Organizers that have used the service.
More to come on this Killer App that will be part of the SIS API Kit.
