Build an appointment scheduler interface integrated with Meta using Amazon Lex and Amazon Connect

This weblog submit is co-written with Nick Vargas and Anna Schreiber from Accenture.

Scheduling buyer appointments is usually a guide and labor-intensive course of. You may make the most of advances in self-service expertise to automate appointment scheduling.

On this weblog submit, we present you methods to construct a self-service appointment scheduling answer constructed with Amazon Lex and Amazon Join. This answer permits customers to create appointments by way of Meta Messenger, and obtain appointment confirmations by an SMS cell message. It additionally offers a web-based dashboard so you possibly can present name to customers with single-click button on the scheduled time.

Amazon Lex integrates with Meta messenger and can be utilized to allow chat conversations. Lex is a fully-managed synthetic intelligence (AI) service with Pure language understanding (NLU) to design, construct, check, and deploy conversational interfaces in functions.

Answer overview

The structure diagram under exhibits a high-level overview of the interplay between completely different AWS parts and companies. The answer consists of those major parts: buyer interplay utilizing Meta messenger, appointment scheduling by way of SMS enabled by Lex and a buyer outbound dialer from Join. This outbound dialer makes it simple to create an outbound name to the client from a easy UI interface.

This submit makes use of the next pattern bot dialog:

Person: I wish to guide an appointment.
Agent: What appointment can I get you? You may say Billing, Common or Gives.
Person: Billing
Agent: What’s your first title?
Person: Sameer
Agent: What’s your cellphone quantity with nation code?
Person: +10001234567
Agent: When ought to I schedule your Billing appointment?
Person: Subsequent week Tuesday
Agent: At what time ought to I schedule the Billing appointment?
Person: 9:00 am
Agent: Sameer, 09:00 is on the market, ought to I’m going forward and guide your appointment?
Person: Sure
Agent: Thanks Sameer, your appointment is confirmed for 09:00, and we’ve texted the small print to your cellphone quantity.

For the scheduler and buyer notification element, an AWS Lambda handler is used to course of the scheduling request. The appointment data is then saved to a Amazon DynamoDB database. When the knowledge is saved efficiently, a notification is shipped to the client confirming the appointment particulars by way of SMS utilizing Amazon Pinpoint.

A React.js software is created to show the saved buyer appointments from the database in a calendar view format. This makes it simple for workers to determine the shoppers who must be referred to as. A name button from the calendar entry is clicked to provoke the decision. It will instantly place an outbound name request to attach the client with the worker utilizing Amazon Join.
