CC Tutorial6 – S2S Scripts

Want to create S2S cloud code script, but don’t know where to start?

In this tutorial, we will take you through the process of creating a simple S2S script, and calling it from an external client (Postman).

Step 1 – Create the S2S Script (AddNumbers)

  • Go to the brainCloud Portal and open the Design | Cloud Code | Scripts page
  • Click the [+] Plus icon to start adding a new Script
  • Give the Script a name and description. Also, ensure the [x] S2S checkbox is checked.
    Note: Client callable is optional, but it’s a good idea to disable it if the script will never be used client side.
  • Create some Test Parameters to use. For this tutorial, enter:
    { “a”: 4, “b”: 3 }
  • You’re done in the Details tab, click on the Editor tab. Here, enter the following:
var response = {};
response.answer = data.a + data.b;

Note: The last line is always what will be returned in the response.

  •  You should have something that looks like this after.
  • The last tab is the Run tab. Here, you can do a [Quick Authenticate], and [Run] your new script to view the return!
    ([Save] and [Close] when you are done editing and testing your script)

Step 2 – Configure an S2S Server to call it from

  • Now go to the brainCloud Portal and open the Design | Cloud Code | My Servers page, and click [New Server]
  • Enter a name for your server, such as APP_SERVER, and click save. This will generate a secret for your server
    Note: You can also limit the IP ranges for your server. This is highly recommended for production deployments.

Your script and server should now be visible in the S2S Explorer.

Step 3 – Call it!

  • Let’s try calling it from Postman!  (If you don’t already have it, you can download it from here.)
  • Launch Postman, and configure a new request.
  • Set the request type to “POST”
  • Set the request URL to “https://sharedprod.braincloudservers.com/s2sdispatcher”
  • Send the following in the body (setting a type of “raw”, sub-type “JSON”), replacing the:
    • gameId with your appId
    • serverName with the name of the server that you configured above in step 2
    • and the gameSecret with the secret of the server that you configured above in step 2
    "gameId": "11549",
    "serverName": "APP_SERVER",
    "gameSecret": "97e1d95d-69f4-472e-904f-39f372777aee",
    "service": "script",
    "operation": "RUN",
    "data": {
        "scriptName": "AddNums",
        "scriptData": {
            "a": 3,
            "b": 4
  • Hit [Send]. If you app is properly configured, you should see this response:
    "response": {
        "answer": 7
    "success": true

Step 4 – Experiment!

That’s cool, but let’s try exercising the brainCloud API?  Try creating and executing the following script:

var profileId = "";
//Get the passed in profileId
//ex. {
// "profileId": "c82b45c0-d906-42a9-8879-2db9c9d8dbc2"
// }
profileId = data.profileId;
//Create a session with that user
var session = bridge.getSessionForProfile(profileId);

//Grab the enity service with the current profile session
var entityProxy = bridge.getEntityServiceProxy(session);

//Now let's create a new entity that will be attached to that profile
var entityType = "address";
var entityData = { "street" : "1309 Carling" };
var acl = { "other": 0 };
var response = entityProxy.createEntity(entityType, entityData, acl);

//And return the response
