About

Kudosity ships in the w6w first-party pack. It declares 18 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

Kudosity (formerly Transmit SMS, Burst SMS and ClickSend-style bulk messaging for Australia, New Zealand, the UK and the US) is an A2P messaging platform: one account, one API key, several channels. This app covers the Transmit Message API v2 — the current, single-key API — so a workflow can send an SMS, an MMS, a templated or free-form WhatsApp message, or an RCS message, and read any of them back with delivery status.

Beyond sending, it can check whether a list of numbers can receive RCS before you choose a channel, list message history per channel with the filters each endpoint documents (cursor-paged for WhatsApp and RCS, page-numbered for SMS), manage the webhooks that push delivery receipts, inbound replies, link hits and opt-outs to your own endpoint, and list the sender registrations on the account.

Health checks probe the v2 gateway without a credential — a schema-correct 401 proves it is serving — because Kudosity publishes no status page and no rate-limit or usage signal. The older Transmit SMS v1 API (key and secret, HTTP Basic) is deliberately not covered here.

Build with Kudosity

Three routes to the same 18 actions. The Workflow tab is generated from Kudosity's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.

Get MMS

mms-get

Retrieve an MMS message and its status by id.

Send MMS

mms-send

Send a multimedia message with media attachments to one recipient.

Check RCS Capability

rcs-capability-check

Check whether phone numbers can receive RCS from your agent, to choose between RCS and SMS before sending.

Get RCS Message

rcs-get

Retrieve an RCS message with its status by id.

List RCS Messages

rcs-list

List RCS messages for the account, newest first, with cursor pagination.

Send RCS Message

rcs-send

Send an RCS text or media message through a registered RCS agent, with an optional SMS fallback. The vendor flags this endpoint as beta.

List Sender Registrations

sender-registration-list

List the sender registrations (numbers and alphanumeric IDs) on the account.

Get SMS

sms-get

Retrieve an SMS message and its delivery status by id.

List SMS

sms-list

List SMS messages, filtered by date, number, sender, reference, status or direction.

Send SMS

sms-send

Send an SMS from a sender number or alphanumeric ID to one recipient.

Create Webhook

webhook-create

Create a webhook that POSTs delivery receipts, inbound messages, link hits or opt-outs to your URL.

Delete Webhook

webhook-delete

Delete a webhook by id.

Get Webhook

webhook-get

Retrieve a webhook by id.

List Webhooks

webhook-list

List the webhooks configured on the account.

Update Webhook

webhook-update

Replace a webhook's settings. Fields left out reset to their defaults, so supply every setting you want to keep.

Get WhatsApp Message

whatsapp-get

Retrieve a WhatsApp message with its status and delivery events by id.

List WhatsApp Messages

whatsapp-list

List WhatsApp messages for the account, newest first, with cursor pagination.

Send WhatsApp Message

whatsapp-send

Send a WhatsApp text, pre-approved template or custom Meta Cloud API message to one recipient, with an optional SMS fallback.

A workflow step names the app and the action, and the editor fills in the connection when you pick one. This is the Step shape from the workflow spec, carrying Kudosity's real ids.

+13 more actions available

Every app-specific value here is a blank you have to fill in. An app action is reached through the connection that authenticates it, so the address is a connection id, not the app id — and connections belong to your account, so a public page cannot know yours. Create one for Kudosity, then fill in the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the parameters that action declares. The call itself is real — the shape is transcribed from the studio's own snippet builder, which prints the same kind of blanks — but nothing in it is specific to Kudosity. The Workflow tab is where this app's real ids are.

Install
npm install @w6w/sdk
yarn add @w6w/sdk
pnpm add @w6w/sdk
deno add npm:@w6w/sdk
Code
import { W6wClient, isActionRun } from "@w6w/sdk";

// Reads W6W_BASE_URL and W6W_TOKEN from the environment when omitted.
const client = new W6wClient();

const envelope = await client.run({
  urn: "conn_YOUR_CONNECTION_ID",
  action: "mms-get",
  payload: {
    id: "<value>",
  },
});

if (isActionRun(envelope)) console.log(envelope.value);
Install the CLI
npm install -g @w6w/cli
CLI
w6w run conn_YOUR_CONNECTION_ID --action mms-get --payload '{"id":"<value>"}'

Give an AI agent Kudosity — without giving it Kudosity's credentials. One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.

One tool call
{
  "name": "w6w_invoke",
  "arguments": {
    "ref": "app:io.w6w.kudosity#mms-get",
    "input": {
      "id": "<id>"
    }
  }
}

Every tool names its target with a single ref. The app: form above doesn't name a connection at all — the host resolves which of the caller's Kudosity connections to sign with, and refuses rather than guesses when the answer is ambiguous.

What the agent gets

Credentials it can't read

The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.

A tool surface scoped to the caller

Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.

A durable workflow in one call

Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.

Health-aware discovery

Kudosity's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.

The MCP surface is part of the hosted platform. Kudosity itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

Kudosity declares its own checks, so its health is a property of the app rather than something the host guesses at.

service

Kudosity API reachability

Unsigned GET https://api.transmitmessage.com/v2/webhook. A 401 carrying the gateway's own `{"status": "..."}` body passes. Kudosity publishes no status page.
