MisarReach Dart SDK #

Dart client for MisarReach — find leads, enrich and verify them, then work them through a CRM pipeline and multi-channel outreach.

17 resource groups · 94 operations

Works on Dart 3, on native platforms — the client imports dart:io, so it suits server-side Dart, CLI tools and native app targets rather than the web. Maps in, maps out. Talks to https://api.misar.io/reach/api.

Install #

dart pub add misarreach

Or add it by hand:

# pubspec.yaml
dependencies:
  misarreach: ^5.0.0

Requires Dart >=3.0.0 <4.0.0 and pulls in http: ^1.2.0. The client imports dart:io, so it targets native platforms — it is not web-compatible.

Authentication #

Create a key in Settings → API keys in the MisarReach app. Reach keys start with mrk_ and are validated against the reach-owned key table only, so a key from another Misar product is rejected. It travels as Authorization: Bearer mrk_….

import 'package:misarreach/misarreach.dart';

final reach = MisarReachClient(apiKey: Platform.environment['MISARREACH_API_KEY']!);

apiKey: is a required named argument. baseUrl:, maxRetries: and timeout: are optional. Call reach.close() when you are done — the client holds an http.Client that keeps the isolate alive until it is released.

Quick start #

import 'package:misarreach/misarreach.dart';

Future<void> main() async {
  final reach = MisarReachClient(apiKey: 'mrk_your_key');

  final job = await reach.leads.search({
    'query': 'CTOs at Series A fintech',
    'useAI': true,
  });

  final snapshot = await reach.leads.job(job['jobId'] as String);
  final results = snapshot['results'] as List<dynamic>;
  print('${(snapshot['job'] as Map)['status']} — ${results.length} leads');

  reach.close();
}

What's in the package #

MisarReachClient — constructed with a named apiKey argument. Resources are plain fields on the instance: reach.leads, reach.deals, reach.plan, …
```
MisarReachClient({
  required String apiKey,
  String baseUrl = 'https://api.misar.io/reach/api',
  int maxRetries = 3,
  http.Client? httpClient,
})
```
Call reach.close() when you are done to release the underlying http.Client — a long-lived process that never closes it leaks a connection pool.
17 resource classes, all exported by name so you can type your own helpers against them: LeadsResource, DealsResource, PipelineResource, ChannelsResource, AutopilotResource, SalesAgentResource, CampaignsResource, ContactsResource, ConversationsResource, CampaignTemplatesResource, DeliverabilityResource, NotificationsResource, WebhooksResource, WorkspacesResource, SettingsResource, AdsResource, PlanResource. Between them they expose 94 methods, one per API operation — the full 70-path / 94-operation surface of openapi/reach.openapi.json.
No generated model classes. Every call returns Future<Map<String, dynamic>> and takes Map<String, dynamic> where a body is required, matching the open-shape API contract. Read fields with a cast: job['jobId'] as String. A 2xx with an empty body decodes to {}, and a top-level JSON array is wrapped as {'data': [...]}. ReachSseEvent is the one typed shape in the package.
Errors — MisarReachError and the typed subclasses below. All implement Exception.
Transport — package:http with a Bearer header, and it does retry: 429, 500, 502, 503 and 504 are retried up to maxRetries attempts (default 3, so two retries), honouring a Retry-After header when the server sends one and otherwise backing off 300 ms · 2ⁿ. A dropped connection (http.ClientException) is retried on the same schedule. A 402 plan refusal is never retried, because retrying cannot help. Note that a 429 carrying upgrade: true is currently retried before it surfaces as UpgradeRequiredError — the outcome is correct, but it costs the back-off delay first.
SSE streaming for lead-finder job progress, as a plain Dart Stream<ReachSseEvent>. The server sends named events — progress, found, complete, error, timeout — plus a : keepalive comment every 20 seconds, which the parser skips. There is no [DONE] sentinel; the stream simply ends when the server closes it. A job that has already finished is answered with a JSON snapshot rather than a stream, and the SDK synthesises the terminal complete/error frame from it, so a caller that assumed a stream does not hang on nothing.

Usage #

Find leads #

leads.search() returns a job id, not leads — the search runs asynchronously and answers 202.

final job = await reach.leads.search({
  'query': 'heads of ops at logistics startups',
  'useAI': true,
  'filters': {'location': 'Berlin', 'companySize': '11-50'},
});
final jobId = job['jobId'] as String;

Stream job progress #

await for (final evt in reach.leads.streamJob(jobId)) {
  switch (evt.event) {
    case 'progress':
      print('working ${evt.data}');
    case 'found':
      print('hit ${evt.data}');
    case 'complete':
    case 'error':
    case 'timeout':
      print('${evt.event} ${evt.data}');
  }
}

await for cancels the subscription when you break, which closes the connection — without that, a stuck job holds it open until the server's own 15-minute ceiling.

List saved leads #

final page = await reach.leads.list(params: {'page': 1, 'limit': 50});
print('${page['total']} saved leads');

Create a CRM contact and a deal #

await reach.contacts.create({
  'email': 'cto@acme.com',
  'firstName': 'Dana',
  'status': 'subscribed',
  'consent': {
    'source': 'signup form /pricing',
    'timestamp': DateTime.now().toUtc().toIso8601String(),
  },
});

// `leadEmail` is the only required field on a deal.
final created = await reach.deals.create({
  'leadEmail': 'cto@acme.com',
  'leadName': 'Dana Reyes',
  'value': 12000,
  'currency': 'USD',
});
final dealId = (created['deal'] as Map)['id'] as String;

Read and move the pipeline #

final board = await reach.pipeline.get();
print('${board['revenue']} across stages ${board['stages']}');

// A stage move is a POST to the same pipeline route.
await reach.pipeline.update({'dealId': dealId, 'newStage': 'meeting'});

Run a campaign #

// Steps are flat: the server assigns `step_order` from the array position and
// builds the template from `subject`/`body`.
final campaign = await reach.campaigns.create({
  'name': 'Q3 fintech outbound',
  'steps': [
    {'channel': 'email', 'subject': 'Quick question', 'body': 'Hi {{name}} …'},
    {'channel': 'email', 'delay_hours': 72, 'body': 'Following up …'},
  ],
});

final result = await reach.campaigns.enqueue(campaign['id'] as String, {
  'recipients': [
    {'email': 'cto@acme.com', 'name': 'Dana Reyes', 'company': 'Acme'},
  ],
});

// Check `warnings`: a step whose channel has no inbound path in this deployment
// can never deliver, and the server reports that here rather than silently
// dropping every recipient at dispatch time.
print('${result['queued']} queued, ${result['skipped']} skipped, '
    '${result['warnings']}');

Check the plan before an expensive run #

final plan = await reach.plan.get();
final usage = plan['usage'] as Map<String, dynamic>;
final searches = usage['lead_searches'] as Map<String, dynamic>;

if (searches['remaining'] == null) {
  print('unlimited lead searches on ${(plan['plan'] as Map)['name']}');
} else if (searches['remaining'] == 0) {
  print('no searches left; upgrade at ${(plan['upgrade'] as Map)['url']}');
} else {
  print('${searches['remaining']} lead searches left');
}

Reply into a conversation #

final inbox = await reach.conversations.list(params: {'limit': 25});
print('${(inbox['conversations'] as List).length} threads');

// The field is `message`, and the channel is chosen server-side from the
// thread — you do not pass one.
await reach.conversations.reply('cto@acme.com', {
  'message': 'Happy to walk you through it — does Thursday work?',
});

Errors #

Every non-2xx throws a MisarReachError or one of its subclasses.

Class	Thrown for
`AuthError`	401 and 403 — missing, invalid or out-of-scope `mrk_` key
`NotFoundError`	404
`RateLimitError`	429 rate limiting; carries `retryAfter`, `balance`, `freeRemaining`
`UpgradeRequiredError`	a plan cap was hit — see below
`MisarReachNetworkError`	connectivity failure; `status` is `0`
`MisarReachError`	any other non-2xx; carries `status`, `code` and the decoded `body`

Order your on clauses subclass-first — on MisarReachError catches every one of them.

The same mapping applies to the SSE stream, so a plan refusal on leads.streamJob() arrives as the same typed error, not a bare exception.

The 402 upgrade case #

A counted plan cap answers 402 with upgrade: true — not 403, and not 429. Retrying cannot help until the cap resets or the plan changes, so the retry loop skips it and the error surfaces immediately:

try {
  await reach.leads.discover({'domain': 'acme.com'});
} on UpgradeRequiredError catch (err) {
  // e.g. feature "lead_searches", current 50 of limit 50
  print('${err.feature}: ${err.current}/${err.limit}');
  print('upgrade at ${err.upgradeUrl}'); // resolved to an absolute URL
}

upgradeUrl resolves the app-relative path the server sends against https://misarreach.com, so it is always absolute.

429 is still accepted as an upgrade refusal when upgrade: true is present, for older deployments. This is distinct from the 503 retry: true the server sends when it could not check the quota — that one is retried, so "we don't know" is never mistaken for "you're over your limit".

Reading `remaining` #

In plan.get(), a usage entry's limit is null when the plan is unlimited for that counter, and remaining is null alongside it — deliberately not 0, which would read as exhausted. Test for null before comparing.

Compliance #

Outreach is not uniformly permitted. Email is the only cold-capable channel; SMS and WhatsApp require a consent record, and several social channels may only reply inside a window the recipient opened. The API enforces this server-side and will refuse a send rather than let you breach TCPA, CASL or GDPR — a refusal is the SDK working correctly, not an error to retry around. Sends are also blocked until a CAN-SPAM sender postal address is set via settings.setSenderAddress().
