API Documentation

If you have scripting knowledge, you can take advantage of GridNet's API and begin creating your own tools & devices that control your network.
To navigate this wiki better, please use the navigation on the right side of the screen.


API Actions:

  • Get Network Details
  • Create Zone
  • Delete Zone
  • Zone ID to Name
  • Zone Name to ID
  • Zone List
  • Zone Channel List
  • Create Channel
  • Delete Channel
  • Channel Name to ID
  • Channel ID to Name


How to make an API Call:

Before you can make a call to the API, you must first create and obtain an API key from your GridNet dashboard. To do this, log into your GridNet Dashboard, select the network, then navigate to "API" and select "Add API Key" to generate a new API Key.

If you aren't the owner or manager of a network and you'd like to use the API, you'll need to check with network owner about acquiring one.


Prerequisites:

You'll need to include the following global functions & variables into your script in order to successfully call an API action: 

string network_api_key = "YOUR-NETWORK-API-KEY-GOES-HERE";
key req_id;

string GenerateHash(string api_key, string data) {
    return llSHA1String(api_key+""+llStringToBase64(data));
}

SendToServer(string json_data) {
    string hash = GenerateHash(network_api_key, json_data);
    req_id = llHTTPRequest("https://gridnet.nexus-sl.net/api/index.php?",[
        HTTP_METHOD,"POST",
        HTTP_MIMETYPE,"application/x-www-form-urlencoded"
    ],"hash="+hash+"&api_key="+network_api_key+"&data="+llStringToBase64(json_data));
}

All API Calls are sent to our server in JSON format. Each function listed below contains the list of requirments that you must first set in your JSON string prior to executing the SendToServer(string json_data) function.

Complete API Examples

We've put together a couple of examples demonstrating how to use the GridNet API in your own scripts.

Example One - Get Network Details

string network_api_key = "INSERT-API-KEY-HERE";
key req_id;

string GenerateHash(string api_key, string data) 
{ 
    return llSHA1String(api_key+""+llStringToBase64(data)); 
}

SendToServer(string json_data)
{
    string hash = GenerateHash(network_api_key, json_data);
    req_id = llHTTPRequest("http://gridnet.nexus-sl.net/api/index.php?",[
        HTTP_METHOD,"POST",
        HTTP_MIMETYPE,"application/x-www-form-urlencoded"
    ],"hash="+hash+"&api_key="+network_api_key+"&data="+llStringToBase64(json_data));
}

default 
{
    touch_start(integer n) {
        if(llDetectedKey(0) == llGetOwner()) {
            string json = llJsonSetValue("",["action"],"get_network_details");
            SendToServer(json);
        }
    }
    http_response(key i, integer s, list m, string b) {
        if(i == req_id)
            llOwnerSay(b);
    }
}

Example Two - Create a New Zone

string network_api_key = "INSERT-API-KEY-HERE";
string json;
key req_id;
integer chan;
integer handle;

string GenerateHash(string api_key, string data) {
    return llSHA1String(api_key+""+llStringToBase64(data));
}

SendToServer(string json_data) {
    string hash = GenerateHash(network_api_key, json_data);
    req_id = llHTTPRequest("https://gridnet.nexus-sl.net/api/index.php?",[
        HTTP_METHOD,"POST",
        HTTP_MIMETYPE,"application/x-www-form-urlencoded"
    ],"hash="+hash+"&api_key="+network_api_key+"&data="+llStringToBase64(json_data));
}

default
{
    touch_start(integer n) {
        if (llDetectedKey(0) == llGetOwner()) {
            json = "";
            llListenRemove(handle);
            chan = (integer)(llFrand(1000000000.0) - 1000000000.0);
            handle = llListen(chan, "", llGetOwner(), "");
            llTextBox(llGetOwner(),"Create a New Zone\n\nPlease enter a zone name you'd like to create",chan);
        }
    }
    
    listen(integer channel, string name, key id, string message) {
        if (channel == chan && id == llGetOwner()) {
            message = llStringTrim(message,STRING_TRIM);
            if (message == "") return;
            else {
                json = llJsonSetValue("",["action"],"create_zone");
                json = llJsonSetValue(json,["zone_name"],message);
                SendToServer(json);
            }
        }
    }
    
    http_response(key i, integer s, list m, string b) {
        if (i == req_id) {
            if (llJsonValueType(b,["zone_id"]) == JSON_NUMBER) {
                string zone_id = llJsonGetValue(b,["zone_id"]);
                llOwnerSay("The zone (\""+llJsonGetValue(json,["zone_name"])+"\" - Zone ID: "+zone_id+") has successfully been created!");
            }
            else llOwnerSay("ERROR >> " + b);
        }
    }
}

Example Three - Transmit Message On Global

string network_api_key = "INSERT-API-KEY-HERE";
key req_id;
integer network_id;

string GenerateHash(string api_key, string data) { 
    return llSHA1String(api_key+""+llStringToBase64(data)); 
}

SendToServer(string json_data) {
    string hash = GenerateHash(network_api_key, json_data);
    req_id = llHTTPRequest("https://gridnet.nexus-sl.net/api/index.php?",[
        HTTP_METHOD,"POST",
        HTTP_MIMETYPE,"application/x-www-form-urlencoded"
    ],"hash="+hash+"&api_key="+network_api_key+"&data="+llStringToBase64(json_data));
}

default {
    state_entry() {
        string json = llJsonSetValue("",["action"],"get_network_details");
        SendToServer(json);
    }
    http_response(key i, integer s, list m, string b) {
        if(i == req_id) {
            network_id = (integer)llJsonGetValue(b,["network_id"]);
            state transmit_on_touch;
        }
    }
}

state transmit_on_touch {
    touch_start(integer n) {
        if(llDetectedKey(0) == llGetOwner()) {
            string json = llJsonSetValue("",["action"],"transmit_message");
            json = llJsonSetValue(json,["message"],"Hello World!");
            json = llJsonSetValue(json,["transmit_level"],"global");
            json = llJsonSetValue(json,["network_id"],(string)network_id);
            json = llJsonSetValue(json,["callsign"],"Shymus Roffo");
            SendToServer(json);
        }
    }
    http_response(key i, integer s, list m, string b) {
        if(i == req_id) {
            llOwnerSay(b);
        }
    }
}
