How to switch odds-data providers
Changing the feed under a live product sounds risky, but done right it is boring — which is the goal. This guide is the low-drama way to switch odds-data providers: run the new feed in parallel, map the schema, verify coverage and freshness, then cut over when the evidence says so.
7 min read
The feed under a matched-betting, comparison or trading product is load-bearing, so switching it feels dangerous. It does not have to be. The trick is never to switch blind: run the candidate alongside your current feed until the evidence is overwhelming.
This guide lays out that parallel-run migration, the checks that matter, and the signals that tell you it is safe to cut over.
Why teams switch
Teams move feeds for a few recurring reasons: coverage gaps (a book they need is missing, bet365 being the usual one), freshness that is not what was promised, a schema that is painful to work with, delivery that is expensive to poll, or support that does not answer when a mapping breaks.
Whatever the reason, the migration approach is the same — and the reason becomes your acceptance test. If you are switching for coverage, coverage is what you verify hardest.
Step 1 — Run in parallel
Do not cut over on faith. Get a trial or sandbox key for the new feed and run it alongside your current one, reading both into a comparison harness. You are not shipping the new feed yet; you are watching it.
A parallel run turns migration from a leap into a measurement. It also surfaces the differences that only show up on real data — the fixture both feeds name differently, the market one covers and the other does not.
Step 2 — Map the schema
Every feed models events, selections and markets slightly differently. Map the new feed's schema to your internal model, and confirm a comparison between the two is apples-to-apples before you trust any difference you see.
A feed normalised to one consistent event and selection model makes this step short; a per-book grab-bag makes it long. That is itself a signal about the feed you are moving to.
Step 3 — Verify what you switched for
Now test the thing that made you switch. For coverage: are the books you need present, bet365 included, by name? For freshness: do the timestamps move the way the cadence implies, and does a live freshness surface agree? For matched output: are the pairs, ratings and qualifying figures correct against your own reckoning?
Verify on your real workload, not a toy query. The bank-holiday card with three times the volume is where feeds differ.
- Coverage: your books, by name, bet365 confirmed.
- Freshness: timestamps and a live surface agree with the cadence.
- Matched output: pairs, ratings and gating are correct.
- Delivery: ETag/304 and gzip behave under your real polling.
Step 4 — Cut over with evidence
When the parallel run has agreed for long enough — across a busy period, not just a quiet afternoon — cut over. Keep the old feed available for a short rollback window, then retire it.
Because you switched on evidence rather than a promise, the cut-over is the boring part. That is exactly what you want from a migration.
Step by step
- 01
Get a parallel key
Trial or sandbox key for the new feed; run it alongside your current one, shipping neither change to users yet.
- 02
Map and compare
Map the new schema to your model and confirm a like-for-like comparison between the two feeds.
- 03
Verify your reason
Test hardest the thing you switched for — coverage, freshness, matched output — on your real workload.
- 04
Cut over and keep a rollback
Switch after the parallel run agrees across a busy period; keep the old feed for a short rollback window, then retire it.
Key takeaways
- Never switch blind — run the new feed in parallel until the evidence is overwhelming.
- Map schemas first so any difference you see is real, not a modelling artefact.
- Verify hardest the reason you are switching, on your real workload.
- Cut over after a busy period, keep a short rollback window, then retire the old feed.
Where OddsRelay fits
OddsRelay is built to be switched onto without drama: a trial or sandbox key lets you run it in parallel against your current feed, its one normalised schema keeps the mapping short, and a live coverage and freshness surface lets you verify coverage, bet365 and freshness against the cadence — not a promise. It powers a leading UK matched-betting platform, so the production question is already answered.
Questions
Will switching feeds mean downtime?
Not if you run in parallel. Keep your current feed live, run the new one alongside it against a trial or sandbox key, and only cut over once the evidence agrees. Keep a short rollback window after cut-over.
How long should a parallel run last?
Long enough to cover a busy period, not just a quiet afternoon — the differences between feeds show up under load, on the big fixture days. Let the parallel run agree across that before you cut over.
What should I verify hardest?
The reason you are switching. Coverage buyers verify the books by name (bet365 included); freshness buyers watch the timestamps and the live freshness surface; matched buyers check the pairs, ratings and gating on real data.
