Guaranteed Delivery Sample

This sample demonstrates the Guaranteed Delivery or the Fail Safe Delivery concept.

This sample consists of a REST API called UserRegistrationAPI, an Endpoint called UserRegistrationEP, a Message processor called UserRegistrationMP, a Message store called UserRegistrationMS and two Sequences called UserRegistrationErrorSeq and UserRegistrationResponseSeq.

Also, it contains another REST API called MockAPI to mimic the backend.

UserRegistrationAPI receives the requests and stores them in the massage store. The message processor periodically polls from the message store and forwards the messages to the specified endpoint. The response return from the endpoint is injected to the response sequence. This payload will be logged and dropped at the end.

Deploying the sample

1. Open the sample by clicking on the Guaranteed Delivery card.
2. Give a folder location to save the sample.
3. Open the UserRegistrationMS Message Store artifact and edit its RabbitMQ credentials accordingly.
4. Start the RabbitMQ broker.
5. Build and run the sample in your Micro Integrator.

Running the sample

1. Once the sample is running you will get a runtime services view with the API swagger definition. You can test the API using the swagger editor or follow step 2 for manual invocation.

2. Open a terminal and run the following command to invoke the API.

   curl --location --request POST 'http://localhost:8290/registeruserapi' --header 'Content-Type: application/json' \
   --data-raw '{
