03a_​Call_​the_​prediction_​workflow_​via_​POST_​request

0 ×

Calling a prediction workflow deployed as a REST service. Example scenario: The bank wants to allow applicants to calculate their approximate credit score on the bank's website. An applicant needs to provide their data and click the button on the website. The POST request to the prediction workflow is sent and the prediction is returned to the applicant.
This workflow demonstrates how to prepare the data for the POST request and make such a request in a KNIME workflow but the POST request can be sent from external clients, e.g., a Postman, Python code, a website etc.
