The Betfair API Headache: How to Get Exchange Odds Without the Red Tape

How To Guides January 13, 2026

Looking for the Betfair API? Here’s What They Don’t Tell You Upfront

You found it. The Betfair Exchange API exists, and yes, it’s technically “free” to access. But before you start dreaming of building your next trading bot, let me save you some time.

Here’s what actually happens when you try to get Betfair Exchange odds:

Requirement Reality
Activation Fee £299 one-time fee to go live
Account KYC-verified Betfair account required
Authentication SSL certificates + session tokens
Session Expiry 20 minutes (Italy/Spain), 4 hours (UK)
Testing No sandbox – use real money or delayed data
Geography Blocked in US, most of Asia, and many other regions

And that’s before you’ve written a single line of code. The Betfair API requires you to generate SSL certificates, manage session tokens that expire, and deal with their non-interactive bot login flow. All to access one bookmaker.

The “Third Option” for Betfair Exchange Data

What if you could skip the £299 fee, the SSL certificates, and the session management entirely?

OddsPapi aggregates odds from 300+ bookmakers – including Betfair Exchange. One API key. One authentication method. No certificates.

Feature Betfair Direct API OddsPapi
Cost to Start £299 activation Free tier
Authentication SSL certs + session tokens Simple API key
Session Management Required (expires every 20min-4hr) Not needed
Geo Restrictions Yes (US, Asia blocked) No
Other Bookmakers Betfair only 300+ (Pinnacle, SBOBet, Singbet)
Historical Data Separate paid product Included on free tier

Understanding Betfair Exchange: Back vs Lay Odds

Betfair is an exchange, not a traditional bookmaker. This means you’re betting against other users, not the house. The exchange offers two types of odds:

  • Back odds – The price you can BUY an outcome at (betting FOR something to happen)
  • Lay odds – The price you can SELL an outcome at (betting AGAINST something to happen)

This is what makes exchange data valuable for arbitrage and trading strategies. You can back on one platform and lay on another to lock in profit regardless of the result.

OddsPapi exposes both sides of the Betfair exchange book through the exchangeMeta field:

# Betfair Exchange response structure
{
  "exchangeMeta": {
    "availableToBack": [
      {"price": 3.65, "size": 13.43},
      {"price": 3.60, "size": 137.91}
    ],
    "availableToLay": [
      {"price": 3.70, "size": 68.50},
      {"price": 3.75, "size": 326.30}
    ]
  }
}

That’s the full depth of the exchange order book – multiple price levels with available liquidity at each.

Tutorial: Get Betfair Exchange Odds in Python

Let’s build a working example that fetches Betfair Exchange odds for a Premier League match.

Step 1: Set Up Authentication

First, grab your free API key from oddspapi.io. Authentication is a single query parameter – no certificates required.

import requests

API_KEY = "YOUR_API_KEY"
BASE_URL = "https://api.oddspapi.io/v4"

# All requests use this simple pattern
params = {"apiKey": API_KEY}

Step 2: Find Premier League Fixtures

# Get Premier League tournament (ID: 17)
response = requests.get(
    f"{BASE_URL}/fixtures",
    params={"apiKey": API_KEY, "tournamentId": 17}
)
fixtures = response.json()

# Find fixtures with available odds
for fixture in fixtures:
    if fixture.get('hasOdds'):
        print(f"ID: {fixture['fixtureId']}")
        print(f"{fixture['participant1Name']} vs {fixture['participant2Name']}")
        print(f"Kickoff: {fixture['startTime']}")
        break

Step 3: Fetch Betfair Exchange Odds

# Get odds for a specific fixture, filtered to Betfair Exchange only
fixture_id = "id1000001761300947"  # Man United vs Man City

response = requests.get(
    f"{BASE_URL}/odds",
    params={
        "apiKey": API_KEY,
        "fixtureId": fixture_id,
        "bookmakers": "betfair-ex"
    }
)
data = response.json()

# Access Betfair Exchange data
betfair = data['bookmakerOdds']['betfair-ex']
print(f"Betfair fixture link: {betfair['fixturePath']}")

Step 4: Parse Back and Lay Prices

Here’s the full path to access exchange odds. Market 101 is Full Time Result (1X2).

# Market 101 = Full Time Result
# Outcome 101 = Home Win, 102 = Draw, 103 = Away Win
market = betfair['markets']['101']

outcomes = {
    '101': 'Home Win',
    '102': 'Draw',
    '103': 'Away Win'
}

for outcome_id, outcome_name in outcomes.items():
    outcome = market['outcomes'].get(outcome_id)
    if outcome:
        player = outcome['players']['0']
        exchange = player.get('exchangeMeta', {})

        # Best available back and lay prices
        back_prices = exchange.get('availableToBack', [])
        lay_prices = exchange.get('availableToLay', [])

        best_back = back_prices[0]['price'] if back_prices else None
        best_lay = lay_prices[0]['price'] if lay_prices else None

        print(f"{outcome_name}: Back @ {best_back} | Lay @ {best_lay}")

Output:

Home Win: Back @ 3.65 | Lay @ 3.70
Draw: Back @ 4.0 | Lay @ 4.1
Away Win: Back @ 2.38 | Lay @ 2.40

Step 5: Compare with Pinnacle (Optional)

Want to spot value? Fetch multiple bookmakers in one request:

response = requests.get(
    f"{BASE_URL}/odds",
    params={
        "apiKey": API_KEY,
        "fixtureId": fixture_id,
        "bookmakers": "betfair-ex,pinnacle,sbobet"
    }
)
data = response.json()

# Now you have exchange AND sharp bookmaker odds
for slug, bookmaker_data in data['bookmakerOdds'].items():
    print(f"\n{slug}:")
    market = bookmaker_data['markets'].get('101', {})
    # ... parse prices
