About

APITemplate.io ships in the w6w first-party pack. It declares 5 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

APITemplate.io turns a template designed once in its own editor into PDFs and images generated on demand, and this app is the generation half of that loop: fill a template with data and get back a rendered PDF or image, ready to attach, store or send on from the rest of a workflow.

Beyond generation, it can look up a specific template’s fields before filling it, list every template and object an account has produced, so a workflow can confirm a template still exists — or find last week’s output — without opening the dashboard.

It targets APITemplate.io’s current v2 API rather than the deprecated v1 host some older integrations still point at, so the actions here match what the vendor actually supports today. Account-wide reporting like generation credit remaining isn’t exposed by the API at all, so this app sticks to the two things it can promise: turning a template into a file, and finding the files and templates already made.

Build with APITemplate.io

Three routes to the same 5 actions. The Workflow tab is generated from APITemplate.io'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.

Create Image

create-image

Render a JPEG/PNG image from an APITemplate.io template.

Create PDF

create-pdf

Render a PDF from an APITemplate.io template.

Get Template

get-template

Fetch a single template's HTML/CSS/settings by id. Vendor docs mark this endpoint experimental.

List Generated Objects

list-objects

List previously generated PDFs/images and their metadata.

List Templates

list-templates

List templates available to this account.

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 APITemplate.io's real ids.

{
  "manifestVersion": "2",
  "name": "apitemplateio-example",
  "steps": [
    {
      "id": "create-image",
      "uses": {
        "app": "io.w6w.apitemplateio",
        "action": "create-image",
        "connection": "conn_YOUR_CONNECTION_ID"
      },
      "with": {
        "templateId": "<templateId>",
        "data": "<data>"
      }
    }
  ]
}

Here are some of the things you can do

  • Create Image

    perform
    create-image
  • Create PDF

    perform
    create-pdf
  • Get Template

    read
    get-template
  • List Generated Objects

    read
    list-objects
  • List Templates

    read
    list-templates

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 APITemplate.io, 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 APITemplate.io. 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: "create-pdf",
  payload: {
    templateId: "<value>",
    data: "<value>",
    // filename: "<value>",
    // expiration: "<value>",
    // isCmyk: "<value>",
    // pdfStandard: "<value>",
    // meta: "<value>",
  },
});

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

Give an AI agent APITemplate.io — without giving it APITemplate.io'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.apitemplateio#create-image",
    "input": {
      "templateId": "<templateId>",
      "data": "<data>"
    }
  }
}

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 APITemplate.io 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

APITemplate.io'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. APITemplate.io itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

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

service

APITemplate.io platform status

No machine-readable status surface: status.apitemplate.io (UptimeRobot-hosted) publishes no RSS/Atom feed or JSON API.

quota

Generation credit headroom

Not exposed: APITemplate.io's v2 API and SDKs document no account/credits/usage endpoint or quota response headers.
