Typed clients for every /v1 operation: organizations, members, projects, tasks, daily plan, attachments, API keys, webhook endpoints, usage.
RFC 9457 problem+json error hierarchy with a stable code on every error.
Rate-limit-aware retries that honor Retry-After.
Automatic Idempotency-Key generation on consequential POSTs — retries can never double-create.
Cursor auto-pagination (for await) with a page escape hatch.
Standard Webhooks signature verification for your webhook receiver.

Install

npm install @nowgetitdone/sdk

Requires Node.js 20+. TypeScript types are bundled; zod is the only dependency (types).

Quickstart

Create an API key in app.nowgetitdone.com under Settings → API keys, then:

import GetItDone from '@nowgetitdone/sdk'

const client = new GetItDone({
    apiKey: process.env.GETITDONE_API_KEY, // gid_… (defaults to this env var)
})

const task = await client.tasks.create({
    title: 'Ship the integration',
})
console.log(task.id) // "T-123"

for await (const t of client.tasks.list({ limit: 50 })) {
    console.log(t.id, t.title, t.status)
}

The SDK is server-oriented: an API key is a secret, so constructing the client in a browser throws unless you explicitly pass dangerouslyAllowBrowser: true.

Errors

Every non-2xx response throws a typed error carrying the API's RFC 9457 problem document. Branch on error.code — it is a frozen vocabulary; title and detail are for humans.

import { APIError, RateLimitError, NotFoundError } from '@nowgetitdone/sdk'

try {
    await client.tasks.retrieve('T-999')
} catch (err) {
    if (err instanceof NotFoundError) {
        // err.code === 'resource_not_found'
    } else if (err instanceof RateLimitError) {
        // err.code: 'rate_limited' (burst) vs 'quota_exhausted' (plan period)
        console.log(err.isQuotaExhausted, err.retryAfterSeconds)
    } else if (err instanceof APIError) {
        console.log(err.status, err.code, err.requestId, err.fieldErrors)
    }
}

Quote err.requestId in support requests — it matches the server's logs.

Retries & idempotency

Network failures, timeouts, 408/429/5xx are retried (default maxRetries: 2) with exponential backoff, honoring Retry-After up to maxRetryAfterSeconds (default 60 — a burst window is worth waiting for, a billing period is not). A POST is never retried without an Idempotency-Key; on consequential POSTs (creates, archive/unarchive, rotate-secret) the SDK generates one automatically and re-sends the same key on every retry, so the server replays instead of re-executing. Pass { idempotencyKey: '…' } per call to control the key yourself.

Pagination

// Auto-iterate every page:
for await (const project of client.projects.list()) { … }

// Or page by page:
let page = await client.tasks.list({ limit: 100 })
while (page) {
    handle(page.data)
    page = await page.getNextPage() // null on the last page
}

Verifying webhooks (your server)

GetItDone signs outbound webhooks per the Standard Webhooks spec. Verify the RAW request bytes — never a parsed-and-reserialized body:

import { verifyWebhook } from '@nowgetitdone/sdk/webhooks'

// e.g. in an Express handler with `express.raw({ type: '*/*' })`:
const result = verifyWebhook({
    headers: req.headers,
    rawBody: req.body.toString('utf8'),
    secret: process.env.GETITDONE_WEBHOOK_SECRET, // whsec_…
})
if (!result.valid) {
    return res.status(400).send(`invalid signature: ${result.reason}`)
}

@nowgetitdone/sdk/webhooks is server-only (node:crypto). During a secret rotation grace window, pass both secrets: secret: [current, previous].

Escape hatches

// Raw request with the client's auth/retry/timeout behavior:
const { data, response, requestId } = await client.request({
    method: 'GET',
    path: '/v1/usage',
})

// Per-call overrides:
await client.tasks.create(
    { title: 'urgent' },
    { timeoutMs: 5_000, maxRetries: 0, signal: abortController.signal },
)

Configuration

Option	Default	Notes
`apiKey`	`GETITDONE_API_KEY` env var	`gid_…` organization API key
`baseUrl`	`https://app.nowgetitdone.com`	`GETITDONE_BASE_URL` env var override
`timeoutMs`	`60000`	per attempt
`maxRetries`	`2`	after the first attempt
`maxRetryAfterSeconds`	`60`	larger `Retry-After` ⇒ give up
`authStyle`	`'authorization'`	or `'x-api-key'`
`logger`	none	redacted request/response/retry events
`dangerouslyAllowBrowser`	`false`	API keys are secrets — keep them server-side

Development
