Create a Case using Pega Microservice code from an external system

-
Microservices are a software development technique—a variant of the service-oriented architecture (SOA) architectural style that structures an application as a collection of loosely coupled services.The benefit of decomposing an application into different smaller services is that it improves modularity. This makes the application easier to understand, develop, test, and become more resilient to architecture erosion. In a microservices architecture, services are fine-grained and the protocols are lightweight. For more details, check the internet.

This is a simple exercise to run a sample Pega microservice code using postman API testing tool (3rd party to run REST api-services). To run this exercise, we need to have a local Pega PE running and the PE would need a sample application running with a Case type and all. Before running the Pega PE, make sure to have postman tool running in the machine. To download the postman tool, follow this site: https://www.getpostman.com/. Check this youtube video on how to use postman: https://www.youtube.com/watch?v=t5n07Ybz7yI

Here are the simple steps to follow

 1) Run the Pega PE on Tomcat server
2) Open the Developer portal and open the Case type settings to get the microservice code generated by Pega to create a case from external system
3) Copy the microservice code from above step and paste it in postman tool and add the necessary header/auth settings
4) Run the POST request from the tool and monitor the console for any issues
5) If no issues from the tool then we can get the successful response with the Pega case id (Candidate case in this example)

Below are the screenshots to get an idea on the above mentioned steps



















Please make sure to have your accessgroup pointed with role: PegaRULES:PegaAPI to avoid the issues/errs while running this exercise.

 Note: We can use SOAP UI tool for testing the microservice code. Here is the difference b/w SOAP UI and Postman: https://techonestop.com/soapui-alternative-for-webservice-testing

Connecting Claude to Pega Infinity 25.1.3 via MCP — Step-by-Step

-
Image
Enable AI-powered access to your Pega Investigative Case Management data directly from Claude prompts using the Model Context Protocol (MCP) and OAuth 2.0. What is MCP and why connect Pega to Claude? The Model Context Protocol (MCP) is an open standard that lets AI assistants like Claude securely call tools and read data from external systems — all from a natural-language prompt. Think of it as a universal adapter between your enterprise systems and AI. Pega Infinity V25.1.3 ships with a first-class MCP service built on its existing REST framework. Once enabled, Claude can: Query and summarize investigative cases without switching apps Retrieve assignment details and case status on demand Trigger Pega workflows from conversational prompts Version requirement: This guide is based on Pega Infinity V25.1.3 (Community Edition) with the Rule-Service-MCP rule type. Earlier versions may not include native MCP support. Architecture overview The connection uses three layers: Claude as the AI c...

itextpdf API to generate PDF doc from an image file using Pega PE

-

Probably some of the techies might have an idea on an opensource called " itextpdf " (earlier name is lowagie ) to convert an image file(png,jpeg,jpg,tiff,gif etc.) to a PDF file. It is very simple to use this API in Pega function to build the logic using java code. Moreover, this API comes in one single jar file and we need to import it in Pega before we start using it.  I see the conversion comes good in PDF file but not sure if any limitations of this API in terms of conversion is like formatting, font, images etc. So far so good and may be we can keep this API as one of our solutions while working on the requirements accordingly.  Heard that same API can be used to convert the text file to PDF but I didn't explore on it. Those who are interested to work on text -> PDF can take a look at the documentation. Don't hesitate to contact me offline for any further discussion in this context :) :) Prerequisites for doing this exercise: 1) itextpdf 5.4.0 jar file 2) Peg...

Hugging Face is a platform that provides tools and libraries for natural language processing (NLP), machine learning, and artificial intelligence. It is known for its Transformers   library, which offers pre-trained models for tasks such as text classification, translation, question answering, and more. Hugging Face also hosts a model hub where users can share and discover pre-trained models. Hugging Face is useful in various domains, including: Natural language processing (NLP): Provides tools and pre-trained models for tasks like text classification, translation, sentiment analysis, and question answering. Machine learning research: Offers state-of-the-art models and datasets for researchers to experiment and innovate. Data science and analytics: Helps data scientists analyze and interpret large volumes of text data. AI application development: Enables developers to build AI-powered applications with ease using pre-trained models and APIs. A very simple exercise using the google...
