pipelinepy 1.0.4

An Adobe IMS authorization code flow used with the Kafka client for Python (kafka-python-ng).

pipelinepy

This is a Python client callback for the Adobe Pipeline Kafka. It is designed to provide a simple and straightforward interface for authenticating IMS users into Kafka.

Installation

To install the pipelinepy, you can use pip:

pip install pipelinepy

Usage

To use the pipelinepy, you need to import the specified requirements. You can then create a Kafka producer and consumer, and use them to send and receive messages to/ from a Kafka topic.

pip install -r requirements.txt
