Yandex Metrika

Overview

Yandex Metrika (Metrica) provides three APIs:

• Management API — create/edit/delete counters, goals, filters, grants
• Reporting API — retrieve traffic stats, build reports with dimensions & metrics
• Logs API — access raw non-aggregated hit/visit data

Base URL: https://api-metrika.yandex.net

Authentication

All API requests require an OAuth token in the header:

Authorization: OAuth <token>

Getting a token

1. Create an app at https://oauth.yandex.com/?dialog=create-client-entry
2. Select "For API access or debugging"
3. Add scopes:
   • metrika:read — read stats and counter settings
   • metrika:write — create/modify counters, upload data
4. Generate auth URL: https://oauth.yandex.com/authorize?response_type=token&client_id=<app_id>
5. Copy the token from the redirect

Using the token

curl -H 'Authorization: OAuth YOUR_TOKEN' \
  'https://api-metrika.yandex.net/management/v1/counters'

Management API

Counters

Action	Method	Endpoint
List all	GET	/management/v1/counters
Get one	GET	/management/v1/counters/{id}
Create	POST	/management/v1/counters
Update	PUT	/management/v1/counters/{id}
Delete	DELETE	/management/v1/counters/{id}
Restore	POST	/management/v1/counters/{id}/undelete

List counters with filters:

curl -H 'Authorization: OAuth TOKEN' \
  'https://api-metrika.yandex.net/management/v1/counters?status=Active&sort=Visits&per_page=50'

Query params: status (Active/Deleted), sort (Visits/Hits/Uniques/Name), per_page, offset, search_string, permission (own/view/edit), favorite.

Goals

Action	Method	Endpoint
List	GET	/management/v1/counter/{id}/goals
Get one	GET	/management/v1/counter/{id}/goal/{goalId}
Create	POST	/management/v1/counter/{id}/goals
Update	PUT	/management/v1/counter/{id}/goal/{goalId}
Delete	DELETE	/management/v1/counter/{id}/goal/{goalId}

Goal types: url, action, phone, email, messenger, chat, file, social_network, search, payment_system, visit_duration, depth, composite.

Create a URL goal:

curl -X POST \
  -H 'Authorization: OAuth TOKEN' \
  -H 'Content-Type: application/json' \
  'https://api-metrika.yandex.net/management/v1/counter/COUNTER_ID/goals' \
  -d '{
    "goal": {
      "name": "Thank you page",
      "type": "url",
      "conditions": [
        {"type": "contain", "url": "/thank-you"}
      ]
    }
  }'

URL condition types: exact, contain, start, regexp.

Create a JavaScript event goal:

curl -X POST \
  -H 'Authorization: OAuth TOKEN' \
  -H 'Content-Type: application/json' \
  'https://api-metrika.yandex.net/management/v1/counter/COUNTER_ID/goals' \
  -d '{
    "goal": {
      "name": "Form submitted",
      "type": "action",
      "conditions": [
        {"type": "exact", "url": "form_submit"}
      ]
    }
  }'

Then trigger from JS: ym(COUNTER_ID, 'reachGoal', 'form_submit');

  'https://api-metrika.yandex.net/stat/v1/data?preset=sources_summary&id=COUNTER_ID'

Filter Syntax

# Equals
ym:s:trafficSource=='organic'

# Not equals
ym:s:trafficSource!='organic'

# Contains (for strings)
ym:s:startURL=@'blog'

# Greater than
ym:s:pageViews>5

# Multiple values
ym:s:lastTrafficSource=.('organic','direct','referral')

Setting Up a Counter in a Web Project

Next.js / React

For detailed setup patterns, see references/nextjs-setup.md.

The key steps:

1. Load the Metrika tag.js script dynamically via next/script or a useEffect
2. Call ym(COUNTER_ID, "init", { ... }) with your options
3. Track SPA page navigations with ym(COUNTER_ID, 'hit', url) on route change
4. Add a <noscript> pixel fallback

Plain HTML

<!-- Place before </head> or at end of <body> -->
<script type="text/javascript">
  (function(m,e,t,r,i,k,a){m[i]=m[i]||function(){(m[i].a=m[i].a||[]).push(arguments)};
  m[i].l=1*new Date();
  for (var j = 0; j < document.scripts.length; j++) {if (document.scripts[j].src === r) { return; }}
  k=e.createElement(t),a=e.getElementsByTagName(t)[0],k.async=1,k.src=r,a.parentNode.insertBefore(k,a)})
  (window, document, "script", "https://mc.yandex.ru/metrika/tag.js", "ym");
  ym(COUNTER_ID, "init", {
    clickmap: true,
    trackLinks: true,
    accurateTrackBounce: true,
    webvisor: true
  });
</script>
<noscript>
  <div><img src="https://mc.yandex.ru/watch/COUNTER_ID" style="position:absolute; left:-9999px;" alt="" /></div>
</noscript>

Init Options

Option	Default	Description
clickmap	false	Record click coordinates for heatmaps
trackLinks	false	Track outbound link clicks
accurateTrackBounce	false	Accurate bounce rate (true = 15s threshold)
webvisor	false	Enable session replay (Webvisor)
trackHash	false	Track hash changes as page views
ecommerce	false	Enable e-commerce data layer
triggerEvent	false	Fire yacounter{ID}inited when ready

JavaScript API (client-side)

// Track a pageview (SPA navigation)
ym(COUNTER_ID, 'hit', '/new-page', { title: 'Page Title' });

// Reach a goal
ym(COUNTER_ID, 'reachGoal', 'goal_identifier');

// Reach a goal with callback
ym(COUNTER_ID, 'reachGoal', 'purchase', function() {
  window.location = '/thank-you';
});

// Set user parameters
ym(COUNTER_ID, 'userParams', { age: 25, gender: 'male' });

// Set visit parameters
ym(COUNTER_ID, 'params', { order_price: 1500, currency: 'RUB' });

Quotas

• Reporting API: 10 requests per second per token
• Management API: varies by endpoint
• Logs API: limited concurrent requests
• Max 20 metrics and 10 dimensions per report request
• Max limit = 100,000 rows per request

Troubleshooting

Issue	Check
No data in reports	Counter status is Active, tracking code is on all pages
Goal not tracking	Goal ID matches, reachGoal event name matches condition exactly
Stats delayed	Data lag is normal (up to several hours); check data_lag in API response
403 from API	Token has correct scopes (metrika:read / metrika:write)
Sampling applied	Set accuracy=full (slower but precise); check sampled in response
SPA pages not tracked	Add ym(ID, 'hit', url) on route change
