Create Card

• on create card tab put all the data into the form and submit

  • to provide valid OIB you can use OIB Generator

• the POST request will be send to card-producer which is going to serialize the data and push it to Kafka topic

• once card-consumer notices the topic received a new event it will deserialize the data and send it to card-creator API

• card creator will store the data in MySQL database with status PROCESSING

• once we have a generated credit card we want to wait for two minutes (fixed time that simulates a long running process of checking all the requirements)

Check Status

• input the same OIB

• if the two minutes have passed the status should be displayed as DONE
