How to subscribe to Salesforce platform events from Azure logic app and post to Azure dev hub

Gana 6

HI, I am new to Azure and try to do POC to connect Azure with Salesforce and subscribe to salesforce platform events and send them o Azure event hub. However, I am struck up with logic app creation itself. I am not able to redirect to logic app designer even though my logic has deployed successfully. Can I get step by step procedure for connecting salesforce with Azure and subscribing to salesforce events ?

@Gana Thanks for reaching out. To make yourself comparable with the logic app I will suggest you to start with the different offerings in logic app i.e. Single tenant logic app (Standard SKU) and Consumption logic app. You can also refer to this document which talks about different environments in the logic app.

I will also suggest you to get familiar with the trigger and action in logic app. This document covers all the connectors that the logic app supports and it would always be handy for your whenever you are designing any workflow with the different connectors in the logic app.

If you want the logic to get triggered in any of the events that occurred then you need to always refer to the trigger section of any of the supported connector document. In your case, as you want to use trigger your logic app when an event occurs at the salesforce end then there are two triggers available as of now in the logic app and you can refer to trigger section for more details. Similarly, you can refer to the actions that salesforce connector supports.

Once you have the record details you can pass the output/transform it according to your need to the next action i.e. event hub to send the event. You can leverage the send action of the event hub trigger to send the event.

Workflow:
When a record is created (Trigger) --> Send Event

You can refer to Saleforce document how you can connect to the salesforce and Event Hub document to get familiar and steps on working on respective connectors.

Feel free to get back to me if you need any assistance.

Thank you @MayankBargali-MSFT . This is helpful However, I am looking at any connector or workflow from Azure which can subscribe to Salesforce Platform events using CometD and receive those messages from Salesforce. Is it possible using Azure logic app ?

@Gana Thanks for sharing more details. As of now, there is no connector for CometD but want to understand your flow that once the platform event is created you want to forward it to CometD or it is opposite.

Workflow:
Saleforce --> CometD
If it is the above case and if CometD has REST API to send the messages then you can leverage the Native HTTP connector to build the request and call the CometD API to send the message.

Workflow:
CometD --> Salesforce
In the above case if there is REST API to consume the message then again you can leverage the Native HTTP connector to build the request and as per the response, you can Create a record at the salesforce end. You can use a timmer trigger in this scenario to do the recursive call to check if there are any new messages.

Hi @MayankBargali-MSFT ,

Thank you for your response. we want to publish message from salesforce using platform events and push to Azure event-hub so that all subscribers who subscribed to azure event-hub can receive message.Since we cannot publish message directly from salesforce event hub to azure event-hub, we are looking for some connector which can subscribe to our salesforce events using CometD and publish to Azure event-hub.

Also, we cannot post message to Azure even-hub using rest api from salesforce as we easily hit the limits of number API calls we make from salesforce to external application. This solution is not viable incase if we publish millions of records on daily basis.

@Gana Thanks for your response. Have you looked into the workflow that I have shared previously of using Send Event action to send the event to the Azure event hub.
Your logic app workflow will get triggered for every record that you create at the salesforce end and using the output of this trigger you can use/change it as per your requirement and input it to the Send event action.

For your existing records, you can use any of the supported azure connectors and then use Get Records action to get the data and Send event action to send the event to an event hub.

Workflow:
When a record is created (Trigger) --> Send Event

Just hopping in here - that's not what Gana is asking for. You can create custom event payloads in Salesforce and CometD is a service you can subscribe to as a consumer. The logic app connectors you are referring to are crude single-entity listeners on Create/Modify record. If you want to create an event from combined entities you are limited in Logic Apps.
