SF-COMPOSITEGRAPHAPI-HEROKUAPP

This is a Node.js implementation for Salesforce Graph API.

The compositeGraphBuilder.js shows how to use fluent interface to build request for Salesforce Composite Graph API.

Connection between Salesforce and Heroku is implemented using ConnectedApps and uses OAuth 2.0 JWT Bearer Flow for Server-to-Server Integration

Example Implementation

const request = require('./compositeGraphBuilder');

const lead = {LastName : "Trailhead", Company: "Salesforce"};
const leadCompositeRequest = new request.CompositeSubRequestBuilder()
    .withBody(lead)
    .withMethod("POST")
    .withReferenceId("Lead1")
    .withUrl("/services/data/v50.0/sobjects/Lead")
    .build();

const campaign = {Name : "Campaign1"};
const campaignCompositeRequest = new request.CompositeSubRequestBuilder()
    .withBody(campaign)
    .withMethod("POST")
    .withReferenceId("Campaign1")
    .withUrl("/services/data/v50.0/sobjects/Campaign")
    .build();

const campaignMember = {leadId: '@{Lead1.id}', campaignId: '@{Campaign1.id}'};
const campaignMemberCompositeRequest = new request.CompositeSubRequestBuilder()
    .withBody(campaignMember)
    .withMethod("POST")
    .withReferenceId("campaignMember1")
    .withUrl("/services/data/v50.0/sobjects/CampaignMember")
    .build();

const graph1 = new request.GraphBuilder()
    .withGraphId("graph1")
    .addCompositeSubRequest(leadCompositeRequest)
    .addCompositeSubRequest(campaignCompositeRequest)
    .addCompositeSubRequest(campaignMemberCompositeRequest)
    .build();

const graphApiInput = new request.CompositeGraphBuilder()
    .addGraph(graph1)
    .build();

console.log(JSON.stringify(graphApiInput));
