Options to Integrate Chat GPT with Salesforce

Chat GPT

In this section, we will go over the various options for integrating GPT with Salesforce. There are three ways to achieve Chat GPT with Salesforce:

  1. Build a custom integration using the Salesforce APEX to call GPT Model API
  2. Pre-built integration packages or solutions available on the Salesforce AppExchange
  3. Create and Host a GPT model to any public cloud or the local machine

I don’t believe any ISV partner (https://appexchange.salesforce.com/) has already developed a package to integrate with the GPT Model. Also, creating and hosting a GPT model can be a complex task that requires a good understanding of machine learning and artificial intelligence.

GPT-3 is a pre-trained model that OpenAI provides; it is not publicly available to download and host on one’s local server or in the public cloud. So options #2 and #3 are invalid at this moment.

Integrate GPT-3 Model API with Salesforce

To call the predicted text from a Chat GPT model, we need to use the API provided by the service that hosts the GPT model. Send an HTTP request from APEX to a specific endpoint. The body of the request is where you put any needed authentication information or parameters. High-level steps to Integrate Chat GPT with Salesforce

  1. Sign up for an API key from OpenAI
    • Go to the OpenAI website (https://openai.com/) and click on the “Sign In” button in the top right corner of the page.
    • After signing in, click on the “API” button at the top of the page.
    • Click on the “Create an API Key” button on the API page.
    • Provide a name for your API Key and select the permissions you want to grant to the key.
    • Click on the “Create” button to create the key.
  2. Once you have an API key, you can use it to request the GPT-3 API.
  3. The endpoint for generating text from a GPT-3 model is: https://api.openai.com/v1/engines/davinci-codex/completions
  4. You can make a POST request to this endpoint with a JSON payload that includes your API key, the text that you want to generate completions for, and any other parameters you want to use to customize the generated text.
import json
import requests

api_key = "YOUR_API_KEY"
model = "davinci-codex"
prompt = "Write something interesting about Salesforce integration"

headers = {
    "Content-Type": "application/json",
    "Authorization": f"Bearer {api_key}"
}

data = {
    "prompt": prompt,
    "engine": model,
    "max_tokens": 50,
    "stop": ["Salesforce integration"]
}

response = requests.post(
    "https://api.openai.com/v1/engines/davinci-codex/completions",
    headers=headers,
    json=data
)

print(response.json())

Make a GPT-3 API HTTP request in Apex

Http http = new Http();
HttpRequest request = new HttpRequest();
request.setEndpoint('https://api.openai.com/v1/engines/davinci-codex/completions');
request.setMethod('POST');
request.setHeader('Content-Type', 'application/json');
request.setHeader('Authorization', 'Bearer ' + apiKey);
request.setBody(jsonPayload);
HttpResponse response = http.send(request);

if (response.getStatusCode() == 200) {
    // Success, parse the JSON response
    Map<String, Object> jsonResponse = (Map<String, Object>) JSON.deserializeUntyped(response.getBody());
    // process the jsonResponse
}
else {
    // Handle the error
}

This is just an example of how you might call the GPT-3 API provided by OpenAI, different providers might have different endpoints, authentication, and parameter that are needed.

Browse Open API documentation about the endpoints

https://beta.openai.com/docs/models/gpt-3

It’s worth noting that OpenAI only provides the GPT models and not a chatbot service, however, the GPT models can be used as the core of a chatbot. But you will need to build the chatbot architecture, prompt and context management by yourself.

Powerful Automation with No-Code Low-Code feature of Salesforce OmniStudio

Salesforce OmniStudio is a tool to build digital customer experiences tailored to any industry and can deliver automation for any business use case with its No-Code and Low-Code features.

Salesforce OmniStudio is a great tool to create guided interactions that integrate into any industry-specific process. Admins can easily develop guided user experiences without code.

In that process, by only dragging components, the admin can integrate a component with external data. Imagine a developer or administrator consuming external system data in no time and in a scalable manner, all without writing any code.

Show that data, either from Salesforce or external sources, in a contextual screen for a full view of relevant data in a single place.

Why use OmniStudio

It’s a Low Code No Code Platform that enables customers to create guided brand experiences specific to their industry with clicks

Drag-and-drop configuration capabilities

Effortlessly meet the demands of omnichannel service by deploying and updating these interactions across multiple devices and channels

OmniStudio is part of Einstein Automate, which integrates Salesforce automation capabilities across Platform, Einstein, MuleSoft, Industries, and AppExchange to deliver an efficient end-to-end workflow platform

Advantages of Omni Studio

  • Build a guided user flow that is highly customizable by configuration – The power of OmniScripts
  • Build customizable UI to show relevant data in a single screen from multiple data sources just by using clicked-based elements – Flexcards
  • Declarative ETL tool that extracts, transforms and loads data in Salesforce without writing code; operates behind the OmniScripts and Flexcards – DataRaptors
  • Declarative way to retrieve data from Salesforce/third-party services without any additional user interaction; run server-side for greater performance – Integration Procedures

Components of OmniStudio

FlexCards: Cards that display contextual information and actions in an at-a-glance format for a customer. a Datasource Wizard populates a FlexCard with data from one or more sources via point-click integration.

OmniScripts: A guided path to complete a business process. It’s a Modular Architecture in nature. A developer can integrate data from multiple sources (Salesforce or third-party), manipulate the data, and send it back to its source, all from within the OmniScript. The data is captured in the standard JSON format.

OmniScripts has a great feature to dynamically generate documents from templates (MS Word, PDF, and HTML outputs), merge data from any data source and then create and operate on these documents like attaching them to Salesforce records and emailing them to recipients, plus delegate to DocuSign for eSignatures.

DataRaptors: Configurable services for retrieving, transforming, and updating data. A DataRaptor is a mapping tool that enables you to read, transform, and write Salesforce data. There are four types of DataRaptor: Turbo Extract, Extract, Load, and Transform.

Integration Procedures: Declarative feature and server-side processes that execute multiple actions in a single service call. An Integration Procedure is also recommended when you need fast processing of complex data from multiple sources. Server-side processing enables faster performance, since, in most cases, the server is faster than the client at processing data. Combining multiple actions in a single server call prevents round trips to the server. Minimizing client/server calls is beneficial, as more round trips mean slower performance.

DataRaptors and Integration Procedures deliver data to and from UI components. They orchestrate calls to Apex classes, calculation engines, and external application programming interfaces (APIs) to execute whatever business logic is required

Slack Integration with Salesforce

An architect can design Slack Integration with Salesforce in 3 ways:

  1. Salesforce provides a free AppExchange manage package by which a developer can seamlessly automate the bidirectional integration between Slack and Salesforce
  2. There are Slack Apps like Rattle, Troops that provide Salesforce integration capability from the third party. Also, explore Apps in the Slack App directory for other kinds of integration capability
  3. Build your own integration in Salesforce using Slack Webhook
  1. Salesforce for Slack: An AppExchange App by Salesforce to seamlessly send Salesforce records to a Slack channel. Trailhead provides a robust hands-on module on this https://trailhead.salesforce.com/content/learn/projects/integrate-salesforce-with-slack/install-salesforce-for-slack-and-grant-permissions
  2. Slack Apps by Third Party: There are many Third party apps to achieve Salesforce integration, few are even free.
    1. Troops is a very interesting App, update Salesforce record directly from Slack. It automates many Slack workflows. Troops is now a Salesforce company. https://www.troops.ai/
    2. Rattle provides robust Salesforce and Slack integration capability, it’s a license-based product. https://www.gorattle.com/
  3. A developer can build its own integration in Salesforce using Slack API and Webhook. below are high-level steps:
    1. Create an Incoming WebHook in the Slack workspace
    2. Whitelist the Webhook URL in Salesforce Remote Site Setting
    3. Build an APEX class with an Invocable method to call the webhook URL and send the Slack Request. Make use of JSON Generator class to serialize the JSON with standard encoding https://developer.salesforce.com/docs/atlas.en-us.apexref.meta/apexref/apex_class_System_JsonGenerator.htm Also make use of Slack message formatting documentation to format the text for app surfaces https://api.slack.com/reference/surfaces/formatting.
    4. That invocable method now can be called from a Flow or APEX.

Salesforce Social Customer Service

Turn social network posts into cases or leads with Social Customer Service. Service Agents can reply to social network posts from the Service Console.

Salesforce Social Customer Service capability is delivered by Marketing Cloud Social Studio which is integrated with Salesforce Platform seamlessly.

Channels supported as of now:

  1. Facebook
  2. Twitter
  3. Instagram
  4. YouTube

There are two solutions to implement Social Customer Service, Basically, both are delivered by MC Social Studio.

  1. Social Customer Service Starter Pack: Comes with Service Cloud License, General limits are:
    1. Two or fewer social accounts can be tracked. So f you add one Twitter account, you can only add another Twitter account or one Facebook account
    1. No moderation rule, all posts become cases
    1. Instagram and YouTube aren’t available
    1. Can’t customize the default Apex code. The default Apex class creates a social post, social persona, case, and contact, and supports common use cases which can be customizable if you have Social Studio accounts
  • Social Studio accounts Marketing Cloud Social Studio implementation. Connector in Service cloud to integrate with MC Social Studio.

The features are:

  • Create Cases or leads from Social network posts and Assignment Rule to assign the cases to agents
  • Agents can directly respond back to customers to the Social Channels from the Service Console

Render Google Map in Salesforce LWC

To show a Google Map in LWC we have a couple of options, lets’s discuss those first:

  • MAP Base Component in LWC

Out of the Box in Salesforce, no need for additional Google MAP API; Only Plots the traverse points in the map, no route information

https://developer.salesforce.com/docs/component-library/bundle/lightning-map/documentation

  • Google MAP API implementation ONLY in LWC

Technically not possible at this moment due to Security with Lightning Locker Services which protects to run a script from a different domain/CDN

  • Google MAP API implementation with LWC + VF

The only possible design currently is placing a VF inside an LWC to render the Google MAP and show the route. All logic is inside the LWC- VF is only for rendering

  • Buy Field Service Lighting or SALESFORCE MAPS licenses

We will only discuss the Google MAP API implementation with LWC + VF solution in this block. This is the only possible solution that needs customization in LWC, VF and APEX.

Prerequisite: Google MAP API License key for commercial use

Solution and Implementation steps are:

  1. A Quick Action to add a Lightning LWC Button to a page layout to access google form.
  2. Clicking on the button will open an LWC Component, LWC component will get the current record id and will call the apex controller to get the data.
  3. Get all required field information from the Apex controller class.
  4. Pass the Information info to the VF page to render the Google Map.
  5. Google Map is dynamically rendered based on the JSON input received from the LWC component.
  • It has one iframe to host the VF page that will render the Google Map by using the google map javascript library.
    • This solution has one unique challenge – to communicate data from the LWC component to the VF page and from the VF page to send the data to the Google Javascript library. All event sequences need to be followed properly.
    • LWC component will read data from the salesforce object and send the location data to google Map.
  • It plots all the locations to Map with the route.
  • The right-hand side panel shows the distance between each point. All Data is dynamically populated from google maps.

VF code to render Google MAP

Amazon Connect for Salesforce

Amazon Connect for Salesforce is a Manage Package that helps to configure Amazon Connect Computer Telephony integration with Salesforce, it’s a very simple process to receive incoming calls and make outgoing calls right from Salesforce. Now, don’t get confused between Amazon for Salesforce and Service Cloud Voice.

AWS Contact Center is seamlessly integrated with Salesforce by Amazon Connect for Salesforce whereas Service Cloud Voice provides a more sophisticated AI-powered feature on top of the Amazon Connect for Salesforce, but not limited only to AWS Contact Center. Service Cloud Voice provides support for other Partner Telephony and lets you create a Service Cloud Voice contact center that uses a telephony provider of your choice. I will talk about Service Cloud Voice in my next article.

Amazon Connect is a highly scalable, cloud-based contact center service. The Amazon Connect CTI Adapter is the Manage Package that is designed to provide complete cloud-based integration and workflow capabilities between Amazon Connect, Salesforce Service Cloud, and Sales Cloud.

The Amazon Connect CTI integration with Salesforce consists of two components:

  • A Manage package can be installed from the below link

https://appexchange.salesforce.com/appxListingDetail?listingId=a0N3A00000EJH4yUAH

  • An Application deployment at your AWS instance

Encryption in Salesforce

When we talk about Encryption in Salesforce, There are typically three kinds of encryption you may need to secure your data:

  • Encription at rest
  • Encription during transit
  • Encription during usuage

Here we will be going to talk about Encryption at rest which is provided by Salesforce Shield which provided 3 products:

  • Event Monitoring
  • Field Audit Trail
  • Encryption

Encryption

Protect data at rest – Encrypt standard & custom fields, files & attachments

Natively to Salesforce features like Search, Chatter, Relationship work with encrypted data

Bring your Own Key: Customer can manage keys, Customer-driven encryption key lifecycle management

Salesforce Shield

Find more details at https://developer.salesforce.com/docs/atlas.en-us.securityImplGuide.meta/securityImplGuide/salesforce_shield.htm

There are two types of Shield Encryption: Deterministic & Probabilistic. Deterministic encryption is for the field which you need in the where clause in a query but the Probabilistic type ensures extra security than the Deterministic type.

Don’t get confused between Classic encryption and Shield platform encryption, Classic encryption is also provided on top of platform with no cost but it doesn’t support Standard field, File, also it provides 128 bit AES and user access to encryption filed is managed by permission set

Salesforce Unlock Package

There are three kinds of packages one can build in the Salesforce platform, Out of which Salesforce Unlock Package is very powerful for the use-case of project deployment, release management, and CICD.

  1. Manage Package: Metadata is IP Protected, distributed via AppExchange
  2. Unmanage Package : Metadata is not IP Protected, you can protect via password but not a good way of working
  3. Unlock Package: Metadata elements are not locked, use it for modular development

Salesforce Unlock package provides a great way for modular development and release, Best suited for Multi org rollout of core functionalities. The below diagram illustrates the unlock packaging and release via Salesforce CLI. Core reviews can also be automated using Salesforce CLI Scanner plug-in using PMD v6.38.0, ESlint v6.8.0, and RetireJS v2.2.5. My blog on Salesforce Code Review Process has more details on that https://twirltech.in/2021/10/salesforce-code-review-process/

It’s Source driven development and deployment mechanism, comes with Platform, no-cost, fully integrated with developer IDE VS Code

Salesforce Unlock Package

Refer to the Salesforce developer guide to get your hand dirty https://developer.salesforce.com/docs/atlas.en-us.sfdx_dev.meta/sfdx_dev/sfdx_dev_unlocked_pkg_intro.htm
