Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Body

application/json

slug

string

required

URL-safe identifier (lowercase, digits, hyphens). Must be unique per project.

Required string length: 1 - 50

Example:

"order-bot"

name

string

required

Maximum string length: 80

Example:

"Order Bot"

description

string

Maximum string length: 280

runtime

enum<string>

Runtime the function is deployed on.

Available options:

nodejs24

timeoutSec

integer

default:30

Per-invocation timeout in seconds. Event and cron invocations are asynchronous, so a long timeout only bounds cost; a tool called during a live conversation holds up the reply, and a function exposed over HTTP is additionally bounded by the platform's HTTP response limit.

Required range: 1 <= x <= 180

memoryMb

enum<integer>

default:256

Available options:

128,

256,

512,

1024

httpEnabled

boolean

default:false

Whether to expose a public HTTPS URL for this function.

files

object

The project's source files, keyed by path relative to the project root (e.g. index.ts, lib/orders.ts). Imports between them are resolved when the function is built, so a function can be split across as many files as it needs.

Paths must be relative and use forward slashes; .., node_modules/ and package.json are rejected. npm packages are not uploaded here — declare them under dependencies and Zavu installs them. Limits: 200 files and 900,000 bytes for the whole tree.

Show child attributes

Example:

{
  "index.ts": "import { formatOrder } from './lib/orders';\n\nexport default async function handler(event) {\n  return { statusCode: 200, body: formatOrder(event) };\n}\n",
  "lib/orders.ts": "export function formatOrder(event) {\n  return JSON.stringify(event);\n}\n"
}

entrypoint

string

default:index.ts

Which file in files is the entry point. Defaults to index.ts.

Example:

"index.ts"

sourceCode

string

Shortcut for a single-file function: exactly equivalent to sending files with one entry named after entrypoint (index.ts by default). Fully supported — use whichever fits. If both are sent, files wins.

Maximum string length: 900000

dependencies

object

npm dependencies. Keys are package names, values are semver ranges.

Show child attributes

Example:

{ "openai": "^4.20.0" }

Response

Function created.

function

object

required

A Zavu Function — user-supplied TypeScript that runs in Zavu Cloud and reacts to messaging events or HTTP requests.
