Racecards that keep every change traceable.
A horse racing API integration starts with dated racecards, stable race identities, and entry-specific information. Treat declarations and result publications as snapshots that can change.
Start with the fields that matter.
The following is an application-side planning checklist. These names illustrate concepts; they are not a promise that any particular provider uses this contract.
| Field concept | Suggested type | Why it matters |
|---|---|---|
meeting_id | string | Groups races at a meeting. |
race_id | string | Stable race identity, independent of scheduled time. |
entry_id | string | A horse participating in this particular race. |
participation_status | string | Preserve declarations and non-participation states. |
result_revision | string or null | Source revision or documented observation reference. |
Separate horse profiles from entries
A profile can appear across many races, while an entry carries that race’s assignment, declared rider, and participation state. Keep original distance, conditions, and units where interpretation matters. Do not merge records using only similar names.
Make the first version inspectable.
Begin with a small, fictional fixture and write down the expected display for a missing measurement, a revised result, and an unfamiliar status. Keep identifiers and original source values available so a later correction reaches the right record. Do not make a smooth interface substitute for a clear data contract.
The bundled samples use a shared envelope with a sample: true flag, a source reference, an event, a result state, and a sport_data object. The additional fields on this page are design concepts; the small fixture does not attempt to implement every possible field.
Questions for your provider evaluation
Confirm event and historical coverage, field meanings, update and correction behavior, authentication, and the permissions for your intended display. Inspect actual sample responses rather than assuming that a familiar endpoint name guarantees the information you need.
A provider credential and a finished frontend are separate pieces of a production system. This site includes neither a private ingestion service nor secret credentials. Use the local examples to establish the interface behavior before implementing the selected provider’s supported access path.
Does this include betting markets?
No. The material covers informational racecards and results. There are no odds feeds, wagering functions, or outcome recommendations. A production data arrangement and any separately regulated features require their own review.
What is included in the local sample?
A fictional event, three invented entries, illustrative durations, a provisional classification, and selected discipline-specific fields. It is bundled with this site and does not refresh from an external source.
