What does Azure Logic Apps B2B integration entail in TypeScript

Question

Pulumi · Accepted Answer

B2B (Business-to-Business) integration using Azure Logic Apps involves automating workflows that connect different business systems across companies. Azure Logic Apps provides enterprise integration capabilities which can be leveraged to create scalable B2B solutions. The integration typically involves the use of several Azure services, including the Azure Logic Apps, Azure API Management, Service Bus, and integration accounts with agreements and partners set up for different protocols (like AS2, X12, EDIFACT, etc.).

To set up a B2B integration using Azure Logic Apps, you would generally follow these steps in TypeScript:

Establish an Integration Account to manage artifacts such as partners, agreements, schemas, and maps.
Create Logic Apps workflows which may implement specific B2B scenarios, such as real-time message processing or batch processing.
Use connectors provided by Logic Apps to interact with other services and protocols necessary for B2B transactions.
Define B2B agreements between trading partners using industry standard protocols like AS2, X12, or EDIFACT.
Monitor and manage the B2B transactions through Logic Apps' B2B features, which allow visibility on message tracking and lifecycle.

Below, you'll find a TypeScript program that demonstrates how to use some of these resources provided by the azure-native package within Pulumi to set up a B2B integration scenario.

import * as pulumi from "@pulumi/pulumi";
import * as azure_native from "@pulumi/azure-native";

// Note: You need to replace values such as `<...>` with actual values
// for your own environment, such as resource group name, location, integration account name, partner name, and so on.

// Step 1: Create an Azure Resource Group if required
const resourceGroup = new azure_native.resources.ResourceGroup("b2bResourceGroup", {
    resourceGroupName: "<ResourceGroupName>",
    location: "<Location>", // Example: "West Europe"
});

// Step 2: Create an Integration Account to manage B2B artifacts
const integrationAccount = new azure_native.logic.IntegrationAccount("b2bIntegrationAccount", {
    location: resourceGroup.location,
    resourceGroupName: resourceGroup.name,
    integrationAccountName: "<IntegrationAccountName>",
    sku: {
        name: "Standard", // Choose between Basic, Standard and Developer tiers
    },
    // Additional properties can be configured as required
});

// Step 3: Create Integration Account Partners
// Partners are typically other businesses you engage with in B2B transactions
const integrationPartner = new azure_native.logic.IntegrationAccountPartner("b2bPartner", {
    partnerType: "B2B",
    content: {
        b2b: {
            businessIdentities: [{
                qualifier: "ZZ", // Replace with qualifier type such as DUNS, Email, etc.
                value: "<PartnerIdentity>", // Replace with your partner's identity value
            }],
        },
    },
    integrationAccountName: integrationAccount.name,
    partnerName: "<PartnerName>",
    resourceGroupName: resourceGroup.name,
});

// Step 4: Create a logic app to implement B2B workflow
const logicApp = new azure_native.logic.Workflow("b2bWorkflowLogicApp", {
    location: resourceGroup.location,
    resourceGroupName: resourceGroup.name,
    definition: {}, // Define your workflow logic here using Logic Apps Workflow Definition Language (JSON format)
    // Additional properties can be configured as required
});

// Step 5: Create B2B agreements as required
// Agreements define how you communicate with your B2B partner (in this case, AS2 protocol is used as an example)
const agreement = new azure_native.logic.IntegrationAccountAgreement("b2bAgreement", {
    agreementType: "AS2",
    content: {
        aS2: {
            // Define AS2 agreement settings here
            // Ensure to populate the properties based on the AS2 settings required for the communication
        },
    },
    hostIdentity: {},
    guestIdentity: {},
    hostPartner: integrationPartner.partnerName,
    guestPartner: "<GuestPartnerName>", // Replace with guest partner name
    integrationAccountName: integrationAccount.name,
    resourceGroupName: resourceGroup.name,
    agreementName: "<AgreementName>",
});

// Output some of the key resource names
export const rgName = resourceGroup.name;
export const integrationAccountName = integrationAccount.name;
export const integrationPartnerName = integrationPartner.partnerName;
export const logicAppName = logicApp.name;
export const agreementName = agreement.name;

This code is a foundational example illustrating the resources you'd set up for B2B integration using Azure Logic Apps with Pulumi. Each resource has required and optional properties that should be filled out according to the specific needs of your integration scenario.

Remember, the above is a simplified representation and serves to demonstrate the creation of the necessary Azure resources. Real-world B2B workflows involve complex logic that will need to be represented in the definition property of the Logic App and the content property of the Agreement according to the specific protocols and business processes you are implementing.

Don't forget to replace placeholder values like <ResourceGroupName>, <IntegrationAccountName>, <Location>, <PartnerIdentity>, <PartnerName>, and <AgreementName> with actual values that are relevant to your business scenario.

Finally, make sure you have the Pulumi CLI installed and configured to use Azure. To deploy the infrastructure code, you would run pulumi up in the terminal in the directory where your Pulumi project is located.
