# isElpTakerAccess on POST /api/v5/trade/* stops working

Calls to POST /api/v5/trade/*, body parameter isElpTakerAccess on OKX API stopped working on October 31, 2026.

On October 31, 2026, the body parameter isElpTakerAccess was removed from POST /api/v5/trade/* endpoints. Requests that continue to pass this parameter fail since that date. The change follows OKX API's ELP name deprecation deadline.

## What to use instead

Send rpiTakerAccess instead of isElpTakerAccess on place and amend order requests.
