Hi @selvendranr9588
Adobe I/O is a cloud-based gateway to integrate with Adobe API’s, SDK’s and server-less environment that enables developers to easily integrate, extend and customize Adobe’s cloud services. Adobe I/O is adding more APIs to the Adobe I/O Console’s already rich offering, including:
- Adobe Analytics
- Adobe Cloud Platform Data Service
- Adobe Sensei Content AI Services
- Adobe Stock
- Adobe Typekit
- Creative SDK
- PDF Services
- Adobe Campaign
- Adobe Target
- Launch, by Adobe
- Smart Content
Adobe I/O Events allows developers to create event-driven applications via webhooks or functions, using the workflow they want, including third-party apps and services. We will be able to programatically deliver event-based experiences using:
- Adobe Experience Manager
- Adobe Analytics Triggers
- Creative Cloud Assets
To answer your question:
1. If you want to connect to any External API, let's say anykind of REST API or SOAP API, it can directly go from your instance.
2. If you want to make any client side call, it is preferred to make call from AEM using the API based event than calling it directly from client side.
