Doing HTTP API Calls

From SmartBots Developers Docs
Jump to: navigation, search

To invoke HTTP API command, you have to call SmartBots API URL with required parameters. See the full list of HTTP Bot commands here.

The request can be either GET or POST. The returned value format is described down below.

API call constructor - compose and test API queries using simple web form

Passing parameters to API URL

For example, you want to call the say_chat_channel command to say something in local chat.

  1. Take the Bot API URL:
  2. Add required parameters
  3. Parse the response

The resulting query looks like this:

string params = llDumpList2String([
  "action="  + "say_chat_channel",
  "apikey="  + llEscapeURL(yourApiKey),
  "botname=" + llEscapeURL("YourBot Resident"),
  "secret="  + llEscapeURL(botSecretCode),
  "channel=" + "0",
  "message=" + llEscapeURL("Hello there!")

  [HTTP_METHOD,"POST"], params);

Or using smartbotsAPI LSL helper functions:

smartbotsAPI("im", [
    "slname", "Glaznah Gassner",
    "message", "Hi there from API"

If you love JSON responses (see below):

smartbotsAPIJSON("status", []);

Parsing API Response

HTTP APIs return either JSON or URL-encoded string (by your choice). Use "dataType=json" input parameter to get JSON.

JSON (added Jan 2018)

The reply is being returned as a JSON string:

  "result": "FAIL",
  "resulttext": "BOT NOT EXISTS"

Use llJsonGetValue to get values from the response:

    touch_start(integer total_number) {
        llOwnerSay("Requesting bot status...");

        // See SmartBots "LSL Helper Functions" for smartbotsAPIJSON
        smartbotsAPIJSON("status", []);

    http_response(key request_id, integer status, list metadata, string body) {
        // llOwnerSay("API raw response: " + body);
        string status = llJsonGetValue(body, ["status"]);

URL-encoded string

The reply is being returned as a set of variables joined in the same way as URL parameters:


Standard reply variables

There are two standard return variables:

  • result - can be one of:
    OK - command completed successfully
    FAIL - command failed
  • resulttext - contains the detailed explanation of failed commands

Other return variables may contain the query results (for example, "groups" for listgroups).
