Making Rest Calls from IDM Workflow

I attended the Starling Bank Hackathon this weekend and had a great time, I will shortly be writing a longer blog post to talk all about it but before that I briefly wanted to blog about a little bit of code that might be really helpful to anyone building IDM workflows.

The External Rest Endpoint

OpenIDM has an REST API that effectively allows you to invoke external REST services hosted anywhere. You might use this for example to call out to an identity verification service as part of a registration workflow and I made good use of it at the hackathon.

With the following piece of code you can create some JSON and call out to a REST service outside of OpenIDM:
java.util.logging.Logger logger = java.util.logging.Logger.getLogger("")
logger.info("Make REST call)

def slurper = new groovy.json.JsonSlurper()
def result = slurper.parseText('{"destinationAccountUid": "a41dd561-d64c-4a13-8f86-532584b8edc4","payment": {"amount": 12.34,"currency": "GBP"},"reference": "text"}')

result = openidm.action('external/rest', 'call', ['body': (new groovy.json.JsonBuilder(result)).toString(), 'method': 'POST', 'url': 'https://api-sandbox.starlingbank.com/api/v1/payments/local', 'contentType':'application/json', 'authenticate': ['type':'bearer', 'token': 'lRq08rfL4vzy2GyoqkJmeKzjwaeRfSKfWbuAi9NFNFZZ27eSjhqRNplBwR2do3iF'], 'forceWrap': true ])

A really small bit of code but with it you can do all sorts of awesome things!
