Description

This endpoint provides an alternative to polling the /fixtures/odds endpoint and allows you to passively listen for updates. This endpoint leverages the SSE responses of the http protocol.

Specific Parameter Information

include_fixture_updates

This will return any status or start date changes for fixtures that meet the criteria of the passing in data.

Best Practices

While our endpoint supports passing multiple leagues and game ids, we recommend grouping up to 10 leagues per connection.

Notes

Choosing a good key to store the data.

If you are tracking multiple sportsbooks for a Game / Market combination. We would recommend making a key of (Fixture ID + Sportsbook + Market + Name).

If you are tracking a single sportsbook for a Game / Market combination. We would recommend making a key of (Fixture Id + Market + Name).

Common Cases

Case 1: Sportsbook moves main line and DOES NOT have any alternate lines

Original Lines:

Over 5.5 | -110 | is_main=True
Under 5.5 | +110 | is_main=True

Sportsbook changes lines:

Over 5.5 | -110 | is_main=True ----> Over 6.5 | -110 | is_main=True
Under 5.5 | +110 | is_main=True ----> Under 6.5 | +110 | is_main=True

Filter is_main=True:

The events you will receive are:

{event: "locked-odds", data: {"data":[{"bet_name": "Over 5.5", "is_main": True, "bet_price": -110, ....}
{event: "locked-odds", data: {"data":[{"bet_name": "Under 5.5", "is_main": True, "bet_price": +110, ....}
{event: "odds", data: {"data":[{"bet_name": "Over 6.5", "is_main": True, "bet_price": -110, ....}
{event: "odds", data: {"data":[{"bet_name": "Under 6.5", "is_main": True, "bet_price": +110, ....}

Filter is_main=False:

You will not receive any events.

Filter is_main is not set

The events you will receive are:

{event: "locked-odds", data: {"data":[{"bet_name": "Over 5.5", "is_main": True, "bet_price": -110, ....}
{event: "locked-odds", data: {"data":[{"bet_name": "Under 5.5", "is_main": True, "bet_price": +110, ....}
{event: "odds", data: {"data":[{"bet_name": "Over 6.5", "is_main": True, "bet_price": -110, ....}
{event: "odds", data: {"data":[{"bet_name": "Under 6.5", "is_main": True, "bet_price": +110, ....}

Case 2: Sportsbook moves main line and DOES HAVE alternate lines.

Original Lines:

Over 5.5 | -110 | is_main=True
Under 5.5 | +110 | is_main=True
Over 6.5 | +120 | is_main=False
Under 6.5 | -120 | is_main=False

Sportsbook changes lines:

Over 5.5 | -110 | is_main=True ----> Over 5.5 | -120 | is_main=False
Under 5.5 | +110 | is_main=True ----> Under 5.5 | +120 | is_main=False
Over 6.5 | +120 | is_main=False ----> Over 6.5 | -110 | is_main=True
Under 6.5 | -120 | is_main=False ----> Under 6.5 | +110 | is_main=True

Filter is_main=True:

The events you will receive are:

{event: "odds", data: {"data":[{"bet_name": "Over 6.5", "is_main": True, "bet_price": -110, ....}
{event: "odds", data: {"data":[{"bet_name": "Under 6.5", "is_main": True, "bet_price": +110, ....}

Note that we WILL NOT send any locked events for:

Over 5.5 | -110 | is_main=True
Under 5.5 | +110 | is_main=True

Filter is_main=False:

The events you will receive are:

{event: "odds", data: {"data":[{"bet_name": "Over 5.5", "is_main": False, "bet_price": -120, ....}
{event: "odds", data: {"data":[{"bet_name": "Under 5.5", "is_main": False, "bet_price": +120, ....}

Note that we WILL NOT send any locked events for:

Over 6.5 | +120 | is_main=False
Under 6.5 | -120 | is_main=False

Filter is_main is not set

The events you will receive are:
