Web Services Before Operation Rule
The Before Operation Rule is used to calculate attributes before a web service operation call. This rule is used by the Web Services Connector before performing any operation such as Test Connection, Aggregation, and so on.
Input Objects
The following table lists the input Objects for WebServiceBeforeOperationRule:
|
Objects |
Type |
Description |
|
application |
|
The application whose data file is being processed. |
|
requestEndPoint |
|
Current request information. It contains the header, body, context URL, method type, response attribute map, successful response code. |
|
oldResponseMap |
|
The response object returned from earlier endpoint configuration of same operation type like Account Aggregation, Get Object, etc. |
|
restClient |
|
This is a Web Services Client (HTTP Client) object that enables you to call the Web Services API target system. |
|
provisioningPlan |
|
Used to update the payload of the HTTP request. Provisioning plan has an account request which defines the operation to be performed on the account. An account request can contain multiple attributes requests and each attribute request represents an operation on a single account attribute. This argument enables the user to update the body/payload or URL attributes of endpoint object using the provisioningPlan information. |
Return Objects
The Web Service Before Operation Rule uses the following return objects:
sailpoint.connector.webservices.EndPoint
sailpoint.connector.webservices.Map
The rule allows user to return the endpoint object (requestEndPoint) or a map. The map can hold updatedEndPoint and connectorStateMap keys where the value expected is Endpoint (requestEndPoint) and connectorStateMap objects respectively. The connectorStateMap object is a map that contains key and value of the attribute that must be updated in the application through the Before Operation Rule.
Examples of the Before Operation Rule
The following is an example which displays the rule used by the Web Services Connector before performing any operation such as Test Connection, Aggregation, and so on.

}
return requestEndPoint;The following is an example of Web Services Connector executing the Before Operation Rule on a target system API:
import connector.common.JsonUtil;
import sailpoint.connector.webservices.WebServicesClient;
try {
WebServicesClient client = new WebServicesClient();
String url = "http://hostname:portnumber/RestFormDataWS/beforeRuleMock";
Map args = new HashMap();
args.put(WebServicesClient.ARG_URL, url);
client.configure(args);
Map header = new HashMap();
// Information can be fetched from requestEndpoint and updated in the header and body
header.put("Authorization","XXXX XXXX");
header.put("Content-Type","application/json");
List<String> allowedStatuses = new ArrayList();
allowedStatuses.add("2**");
Map payload = new HashMap();
payload.put("jsonBody","{"user":{"userId":"RinkuSharma","firstName":"Rinku","lastName":"Sharma","title":"manager"}}");
String response = client.executePost(url, payload, header, allowedStatuses);
// if response contains token it can be updated in the requestEndpoint header or body
// the requestEndpoint will be used for execution of the particular operation configured
log.info("response: " + response);
} catch (Exception e) {
log.error(e.getMessage(), e);
}The following example displays the Before Operation Rule being used to update the values for endpoint and application attributes before execution of the endpoint:
Map updatedInfoMap = new HashMap();
requestEndPoint.setFullUrl(requestEndPoint.getFullUrl().replaceAll("&&", "&"));
Map connectorStateMap = new HashMap();
connectorStateMap.put("accesstoken","Bearer accessTokenGeneratedInBeforeRuleScript");
updatedInfoMap.put("updatedEndPoint",requestEndPoint);
updatedInfoMap.put("connectorStateMap",connectorStateMap);
return updatedInfoMap;
