Independent and unofficial. en-GB Mon, 12 Oct 2026 00:00:00 +0000 https://openbrokerapi.com/changes IG's REST reference opened on 12 Oct 2026 at labs.ig.com/rest-trading-api-reference.html, after refusing our reader in September. It prints the working order paths with a hyphen: /working-orders, /working-orders/otc and /working-orders/otc/{dealId}. This site had recorded /workingorders, the spelling in IG's own deprecated Java sample. The three records now carry the reference spelling and are marked conflicting, because IG's two sources disagree and neither was tested against a host. The address without .html answered 500 the same day, so the eighteen records that linked it now link the page for their own call.

Required now means only what the page marks as not null: size alone on DELETE /positions/otc; currencyCode, epic, expiry, forceOpen, guaranteedStop and size on POST /positions/otc; currencyCode, epic, expiry, guaranteedStop, level and size on POST /working-orders/otc. The page marks searchTerm optional on the market search. The _method header on deleting a working order is now recorded as optional, not required: IG's reference documents a plain DELETE, and IG's FAQ offers a POST with _method: DELETE only for clients that cannot send a body on a DELETE. This describes IG's page, not a test of what the host accepts.

The IG record links the working addresses. The claims read there are unchanged: the FAQ still gives 12 hours for the session tokens and the guide still gives 6 hours extended up to 72.

It previously said IG's pages name no streaming vendor. labs.ig.com/node/158 was dropped as a second source for two limits, since it showed an out of service notice and the FAQ carries the same figures.
