Create custom endpoints to launch scripts

Custom endpoints let you run arbitrary scripts through the REST API.

A custom endpoint configuration includes an inline script that provides the endpoint functionality.

Custom endpoint scripts

The following custom endpoint script demonstrates all the HTTP operations that can be called by a script. Each HTTP operation is associated with a method (create, read, update, delete, patch, action, or query). Requests sent to the custom endpoint return a list of the variables available to each method.

All scripts are invoked with a global request variable in their scope. This request structure carries all the information about the request.

Read requests on custom endpoints must not modify the state of the resource, either on the client or the server, as this can make them susceptible to Cross Site Request Forgery (CSRF) exploits.

The standard READ endpoints are safe from CSRF exploits because they are read-only. This is consistent with the Guidelines for Implementation of REST, from the US National Security Agency, as "... CSRF protections need only be applied to endpoints that will modify information in some way."

Custom endpoint scripts must return a JSON object. The structure of the return object depends on the method in the request.

Depending on the method, the variables available to the script can include the following:

resourceName

The name of the resource, without the endpoint/ prefix, such as echo.

newResourceId

The identifier of the new object, available as the results of a create request.

revision

The revision of the object.

parameters

Any additional parameters provided in the request. The sample code returns request parameters from an HTTP GET with ?param=x, as "parameters":{"param":"x"}.

content

Content based on the latest revision of the object, using getObject.

context

The context of the request, including headers and security. For more information, refer to Request context chain.

Paging parameters

The pagedResultsCookie, pagedResultsOffset, and pageSize parameters are specific to query methods. For more information refer to Page Query Results.

Query parameters

The queryId and queryFilter parameters are specific to query methods. For more information refer to Construct Queries.

Sample custom endpoint script

(function(){
    if (request.method === "create") {
        return {
            method: "create",
            resourceName: request.resourcePath,
            newResourceId: request.newResourceId,
            parameters: request.additionalParameters,
            content: request.content,
            context: context.current
        };
    } else if (request.method === "read") {
        return {
            method: "read",
            resourceName: request.resourcePath,
            parameters: request.additionalParameters,
            context: context.current
        };
    } else if (request.method === "update") {
        return {
            method: "update",
            resourceName: request.resourcePath,
            revision: request.revision,
            parameters: request.additionalParameters,
            content: request.content,
            context: context.current
        };
    } else if (request.method === "patch") {
        return {
            method: "patch",
            resourceName: request.resourcePath,
            revision: request.revision,
            parameters: request.additionalParameters,
            patch: request.patchOperations,
            context: context.current
        };
    } else if (request.method === "query") {
        // query results must be returned as a list of maps
        return [ {
            method: "query",
            resourceName: request.resourcePath,
            pagedResultsCookie: request.pagedResultsCookie,
            pagedResultsOffset: request.pagedResultsOffset,
            pageSize: request.pageSize,
            queryId: request.queryId,
            queryFilter: request.queryFilter.toString(),
            parameters: request.additionalParameters,
            content: request.content,
            context: context.current
        } ];
    } else if (request.method === "delete") {
        return {
            method: "delete",
            resourceName: request.resourcePath,
            revision: request.revision,
            parameters: request.additionalParameters,
            context: context.current
        };
    } else if (request.method === "action") {
        return {
            method: "action",
            action: request.action,
            content: request.content,
            parameters: request.additionalParameters,
            context: context.current
        };
    } else {
        throw { code : 500, message : "Unknown request type " + request.method };
    }
})();

Custom endpoint configuration

A custom endpoint configuration has the following structure:

{
    "context" : "context path",
    "type" : "script language",
    "source" : "script source"
}
context

string, optional

The root URL path for the endpoint, in other words, the route to the endpoint. An endpoint with the context endpoint/test is addressable over REST at the URL https://<tenant-env-fqdn>/openidm/endpoint/test or using a script such as openidm.read("endpoint/test").

Endpoint contexts support wild cards, as shown in the preceding example. The endpoint/linkedview/* route matches the following patterns:

endpoint/linkedView/managed/realm-name_user/bjensen
endpoint/linkedView/system/ldap/account/bjensen
endpoint/linkedView/
endpoint/linkedView
type

string, required

The script type.

IDM supports "text/javascript".

source

The inline script source.

For example:

"source" : "require('linkedView').fetch(request.resourcePath);"

Sample custom endpoint configuration

{
    "type" : "text/javascript",
    "source" : "<script>"
}

Script exceptions

Some custom endpoint scripts require exception-handling logic. To return meaningful messages in REST responses and in logs, you must comply with the language-specific method of throwing errors.

JavaScript scripts should comply with the following exception format:

throw {
    "code": 400, // any valid HTTP error code
    "message": "custom error message",
    "detail" : {
        "var": parameter1,
        "complexDetailObject" : [
            "detail1",
            "detail2"
        ]
    }
}

Any exceptions will include the specified HTTP error code, the corresponding HTTP error message, such as Bad Request, a custom error message that can help you diagnose the error, and any additional detail that you think might be helpful.
