How to call External Rest Api Using HTTP-Connector

Hello,

I need to set up a Payload, and call a Rest API, this API will return me a JSON, with a response ID. I’m having trouble capturing this response ID to call my next Rest API, because it needs the ID as a parameter. can you help me? How i mount this Payload? and how i get data response?

This is the payload I need to set up:

HTTP POST
{
“email”: “string”,
“name”: “string”
}

Response
{
“id”: “string”,
“email”: “string”,
“name”: “string”
}

After that, I need to get the ID and call my next task. can you help me?

This is my BPMN

We are doing something similar with groovy scripts. We use jsonSlurper to parse the json body and retrieve an ID. We use Jsoup to perform rest calls rather than HTTP-Connector; I have read there are timeout issues with HTTP-Connector. Here’s a snippet that pulls an ID out of a response body and sends a rest call with JSoup:

    def jsonSlurper = new JsonSlurper()
    def eventTypeId = jsonSlurper.parseText(doc.body()).data.ID
    url = baseUrl + version + '/orders/' + detailsId + '/events';
    def str =  "{\"EventType_ID\" : \"" + eventTypeId + "\","  +
                "\"DateCreated\" : \"" + easternTime + "\","  +
                "\"EventData\" : \"" + msg + "\"," +
                "\"username\" : \"" + createdBy + "\"," +
                "\"CreatedBy\" : \"" + createdBy + "\"}";
    doc = Jsoup.connect(url)
        .method(org.jsoup.Connection.Method.POST)
        .header('Accept', 'application/json')
        .header('Content-Type', 'application/json')
        .requestBody(str)
        .timeout(30000)
        .ignoreContentType(true)
        .execute();
