In this tutorial, we'll first do [preprocess the datasets](https://docs.catalyst.zoho.com/en/quickml/help/data-preprocessing/data-cleaning/) to make sure they're tidy and prepared for training. A [data pipeline](https://docs.catalyst.zoho.com/en/quickml/help/create-data-pipeline/) will be built next to handle data transformation, and an [ML pipeline](https://docs.catalyst.zoho.com/en/quickml/help/create-ml-pipeline/) will be built to train and test the model. Finally, we'll provide an [endpoint](https://docs.catalyst.zoho.com/en/quickml/help/pipeline-endpoints/) for the trained model that enables interaction with external apps and provides Credit Card Fraud Detections. The Credit Card Fraud Detection ML model is built using the following Catalyst service: **[Catalyst QuickML](https://docs.catalyst.zoho.com/en/quickml/getting-started/introduction/)** : Using this service, we will first pre-process the sample dataset by implementing [node operations](https://docs.catalyst.zoho.com/en/quickml/help/data-preprocessing/data-cleaning/) on them and constructing the [data pipeline](https://docs.catalyst.zoho.com/en/quickml/help/create-data-pipeline/). This pre-processed data will be used to create an ML model by executing [ML algorithms](https://docs.catalyst.zoho.com/en/quickml/help/ml-algorithms/classification-algorithms/). Finally, this Credit Card Fraud Detection ML model can be accessed by external applications using the [endpoint URL](https://docs.catalyst.zoho.com/en/quickml/help/pipeline-endpoints/) generated in QuickML. The final output, after creating all the required data and ML pipelines in the [Catalyst console](https://console.catalyst.zoho.com/baas/index), will look like this: ![final_output](https://catalyst-docs-development.zohostratus.in/images/tutorials/credit-card-fraud-detection/introduction.webp)
