Use it to invite candidates, check invite quota, manage webhooks, enroll hiring pipelines, and fetch results from your ATS, backend, or automation scripts.

Requires Node.js 18+. Full API reference: https://docs.praxicraft.com

Authentication

Create an organisation API key in Assess:

Assess → Developer → API Keys → create key → copy ct_live_… (shown once).

export PRAXICRAFT_API_KEY="ct_live_xxxxxxxxxxxxxxxx"

Or pass the key when constructing the client:

import { Client } from "@praxicraft/assess";

const client = new Client({ apiKey: "ct_live_xxxxxxxxxxxxxxxx" });

Optional: override the API host with PRAXICRAFT_API_BASE_URL or new Client({ baseUrl }). Default host: https://assess.praxicraft.com.

Never commit API keys. Prefer environment variables or a secrets manager.

Scopes and rotation: Authentication

Quickstart

import { Client } from "@praxicraft/assess";

const client = new Client(); // reads PRAXICRAFT_API_KEY

const page = (await client.assessments.list()) as { results: Array<{ slug: string; status: string }> };
for (const assessment of page.results) {
  console.log(assessment.slug, assessment.status);
}

// Invite a candidate (idempotent on email — safe to retry)
const invite = (await client.invites.create("senior-backend-screen", {
  email: "candidate@example.com",
  name: "Jane Doe",
  send_email: true,
})) as { invite_token: string; invite_url?: string };

console.log(invite.invite_token, invite.invite_url);

const result = await client.results.retrieve(invite.invite_token);
console.log(result);

Responses are flat JSON (same shape as the Public API — no { data: … } wrapper).

What you can do

Resource	Common methods
client.org	retrieve(), stats()
client.assessments	list(), retrieve(), create(), update(), activate(), listTasks(), attachTasks(), replaceTasks(), removeTask()
client.invites	create(), bulkCreate(), list(), retrieve(), remind(), cancel()
client.results	list(), retrieve(), iterAll()
client.webhooks	list(), create(), retrieve(), update(), delete(), test(), deliveries()
client.pipelines	list(), retrieve(), enroll(), bulkEnroll(), listEnrollments(), getEnrollment()
verifySignature	Verify X-Praxicraft-Signature on webhook payloads

All paths target /api/v1/public/… on the Assess host.

Check invite quota before bulk sends

const org = (await client.org.retrieve()) as { invites_remaining?: number };
if ((org.invites_remaining ?? 0) < candidates.length) {
  throw new Error("Not enough invites remaining this month");
}

Register and test a webhook

const hook = (await client.webhooks.create({
  url: "https://example.com/hooks/praxicraft",
  events: ["assessment.completed", "candidate.passed"],
})) as { id: string; secret_key: string };

// Store hook.secret_key (whsec_…) — shown once
await client.webhooks.test(hook.id);
await client.webhooks.update(hook.id, { is_active: true });

Verify webhook signatures

import { verifySignature } from "@praxicraft/assess";

function handleWebhook(rawBody: Buffer, signatureHeader: string, secret: string) {
  return verifySignature(secret, rawBody, signatureHeader);
}

Header format: X-Praxicraft-Signature: sha256=<hex>

Event catalog: Webhooks

Paginate cohort results

for await (const row of client.results.iterAll("senior-backend-screen", { page_size: 50 })) {
  console.log(row);
}

Errors

Branch on error.code (stable), not the message text:

import {
  AuthenticationError,
  InsufficientScopeError,
  RateLimitError,
  ValidationError,
} from "@praxicraft/assess";

try {
  await client.invites.create("demo", { email: "candidate@example.com" });
} catch (err) {
  if (err instanceof ValidationError) {
    console.log(err.code, err.details);
  } else if (err instanceof InsufficientScopeError) {
    console.log(err.code, err.requiredPlan);
  } else if (err instanceof AuthenticationError) {
    console.log(err.code);
  } else if (err instanceof RateLimitError) {
    console.log(err.retryAfter);
  } else {
    throw err;
  }
}
