@goalapi/sdk

JavaScript and TypeScript SDK for the GOAL API: football fixtures, live scores, standings, player stats, odds and live WebSocket updates.

Zero runtime dependencies. Works in Node 18+, Deno, Bun, Cloudflare Workers and browsers.

npm install @goalapi/sdk

Quick start

import { GoalApi } from '@goalapi/sdk';

const goal = new GoalApi({ apiKey: process.env.GOAL_API_KEY });

const { data: live } = await goal.fixtures.live();
for (const match of live) {
    console.log(`${match.homeTeam?.name} ${match.homeScore}-${match.awayScore} ${match.awayTeam?.name}`);
}

Get a key at goal-api.com/signup. Don't ship it in client-side code; proxy through your own backend.

Client options

const goal = new GoalApi({
    apiKey: process.env.GOAL_API_KEY,
    baseUrl: 'https://api.goal-api.com/v1', // default
    timeout: 30_000,                        // per attempt, ms
    maxRetries: 2,                          // 429 + 5xx + network errors
    headers: { 'X-My-App': 'scoreboard' },
});

Retries use exponential backoff with full jitter, and always honour a server-sent Retry-After. Aborted requests are never retried.

Endpoints

Grouped by resource. Full parameter reference in ENDPOINTS.md.

await goal.status.get();                                   // no API key needed
await goal.countries.list({ search: 'spa' });
await goal.leagues.list({ isActive: true, limit: 100 });
await goal.leagues.standings(leagueId);
await goal.leagues.topScorers(leagueId, { limit: 10 });
await goal.teams.get(teamId, { includePlayers: true });
await goal.teams.statistics(teamId, { season: '2025-2026' });
await goal.fixtures.list({ from: '2026-08-01', to: '2026-08-07', status: 'SCHEDULED' });
await goal.fixtures.byDate('2026-08-15', { leagueId });
await goal.fixtures.lineups(fixtureId);
await goal.fixtures.statistics(fixtureId, { half: '1half' });
await goal.standings.form(leagueId);
await goal.players.search('haaland', { limit: 5 });
await goal.players.compare([playerA, playerB]);
await goal.players.top('goals', { limit: 20 });
await goal.coaches.byTeam(teamId);
await goal.h2h.stats(teamA, teamB);
await goal.results.today();
await goal.videos.recent({ leagueId, limit: 10 });
await goal.odds.list({ bookmaker: 'bet365' });
await goal.predictions.list({ matchId });

Every method returns the raw envelope, so pagination and source stay reachable:

const page = await goal.teams.list({ leagueId, limit: 50 });
page.data;                 // Team[]
page.pagination.hasMore;   // boolean
page.source;               // 'cache' | 'database'

One exception: goal.status.*

The five /public/* endpoints don't use the { success, data } envelope. They return bare objects, so read them directly with no .data:

const status = await goal.status.get();
status.status;        // 'operational'
status.components;    // [{ name, status, uptime }]

They also paginate with page/limit instead of limit/offset, so paginate() does not apply to coverageLeagues.

Pagination

paginate walks pages for you and yields items:

for await (const team of goal.paginate((p) => goal.teams.list({ leagueId, ...p }))) {
    console.log(team.name);
}

// Or collect, with a cap:
const first500 = await goal.collect(
    (p) => goal.results.list({ leagueId, ...p }),
    { pageSize: 500, maxItems: 500 },   // /results accepts limit up to 500
);

Default pageSize is 100, the limit ceiling on most endpoints. /results and /countries take 500.

Errors

Everything thrown is a GoalApiError. Branch only where you'd actually behave differently:

import { RateLimitError, ValidationError, NotFoundError, PlanUpgradeRequiredError } from '@goalapi/sdk';

try {
    await goal.fixtures.get(id);
} catch (error) {
    if (error instanceof NotFoundError) return null;
    if (error instanceof RateLimitError) {
        console.warn(`Quota exhausted (${error.rateLimitType}), retry in ${error.retryAfter}s`);
    } else if (error instanceof ValidationError) {
        console.error(error.details);       // which field the server rejected
    } else if (error instanceof PlanUpgradeRequiredError) {
        console.error('This endpoint is not in your plan');
    }
    throw error;
}

Two error shapes

The API answers with one of two bodies, and the SDK normalises both:

	Gateway (auth, routing, rate limits)	Football service (most endpoints)
text	message	error
code	yes	yes
category	yes	no
correlationId	yes	no
details	object	array, on validation errors

So error.message and error.code are always populated, and error.correlationId is only set on gateway errors. Quote it in a support ticket when you have it.

Rate limits

The SDK records the headers from the last response:

await goal.fixtures.live();
goal.rateLimit;   // { limit, remaining, reset, type: 'DAILY' | 'MONTHLY' }

reset is a unix timestamp in seconds.

Live WebSocket updates

The socket is at wss://api.goal-api.com/ws, not /v1/ws. Only nginx's location ^~ /ws carries the Upgrade headers; /v1/ws is proxied as ordinary HTTP and answers 200 instead of upgrading. The SDK derives the right URL for you.

Two services authenticate: the gateway authorises the upgrade from the header or ?wsToken=, then websocket-service needs an {"type": "auth", ...} frame as the very first message. The SDK sends it, and treats auth_success as the point the connection is usable.

subscribe is capped per plan and the cap can be 0. auth_success reports maxSubscriptions; if it is 0 the socket works but no match_update will ever arrive. See the known server issue in ENDPOINTS.md.

const live = goal.live();

live.on('match_update', ({ data }) => console.log(data));
live.on('error', (error) => console.error(error));
live.on('close', ({ code }) => console.log('closed', code));

await live.connect();
live.subscribe(fixtureId);

• Node 22+: works as-is. On Node 18-21, npm i ws and pass it: goal.live({ WebSocket: (await import('ws')).WebSocket }).
• Browsers: the SDK mints a short-lived single-use token via POST /ws/token automatically. The key is still in the page, so put a proxy in front.
• Reconnects automatically with backoff and replays your subscriptions. close() opts out.
• subscribe() before connect() is fine; it's queued and sent on open.
• Server caps client messages at 60/minute and concurrent subscriptions by plan.

Message types you can listen for: match_update, auth_success, status, pong, server_shutdown, error, plus the SDK's own open / close, and '*' for everything.

Webhooks

Verify against the raw body. A parsed-and-reserialized object has different bytes and will never match.

import express from 'express';
import { verifyWebhook, WebhookSignatureError } from '@goalapi/sdk';

const app = express();

app.post('/goal-webhooks', express.raw({ type: 'application/json' }), (req, res) => {
    let event;
    try {
        event = verifyWebhook(req.body, req.headers['x-goal-signature'], process.env.GOAL_WEBHOOK_SECRET);
    } catch (error) {
        if (error instanceof WebhookSignatureError) return res.sendStatus(400);
        throw error;
    }

    switch (req.headers['x-goal-event']) {
        case 'goal.scored': /* ... */ break;
        case 'match.finished': /* ... */ break;
    }
    res.sendStatus(200);   // ack fast; the server retries at ~1m, 5m, 25m, 2h, 10h
});

Signatures use the Stripe scheme: t=<unix>,v1=<hmac-sha256 of "timestamp.body">. Timestamps outside 300s are rejected as replays. Override with { tolerance }.

Escape hatch

For an endpoint this SDK doesn't wrap yet:

const data = await goal.request('/some/new/endpoint', { limit: 10 });

TypeScript

Types ship with the package. Params, methods, enums and errors are fully typed.

Row shapes are not, since they follow the API's response shapes and change. Each endpoint method takes its row type as a type argument instead:

import { GoalApi, type MatchStatus } from '@goalapi/sdk';

interface Fixture { id: string; status: MatchStatus; homeScore: number | null }

const page = await goal.fixtures.live<Fixture>();
page.data[0].homeScore;      // number | null

const raw = await goal.fixtures.live();
raw.data[0]['homeScore'];    // Json, since no type argument was given

It flows through pagination too, so there are no casts anywhere:

for await (const team of goal.paginate((p) => goal.teams.list<Team>(p))) {
    team.name;   // string
}

Examples

File	Shows
examples/basic.js	Status, live fixtures, standings, pagination
examples/live-scores.js	The live socket: connect, subscribe, print every frame
examples/webhook-server.js	Verifying a webhook against the raw request bytes
examples/bulk-export.js	Walking every page of a collection to CSV

GOAL_API_KEY=...          node examples/live-scores.js
GOAL_WEBHOOK_SECRET=...   node examples/webhook-server.js
GOAL_API_KEY=...          node examples/bulk-export.js > countries.csv

Testing

npm test                       # unit tests, no network
GOAL_API_KEY=... npm test      # also runs the live tests against the real API

The live tests skip themselves without a key, so the same command works either way. Endpoint-by-endpoint coverage of the API lives in tools/sweep.py in the SDK workspace.

Other languages

Four more first-party clients over the same API, with the same resource groups, the same retry and pagination behaviour and the same error types. All five release in lockstep, so a version number means the same surface everywhere.

Language	Package	Install
Python	goal-api	pip install goal-api
Go	goal-api-go	go get github.com/goal-api/goal-api-go
Dart / Flutter	goal_api	dart pub add goal_api
PHP	goal-api/sdk	composer require goal-api/sdk

Each one is its own repository and carries the same ENDPOINTS.md, the API contract derived from the running service.
