# POST /tendermint.abci.ABCI/VerifyVoteExtension

`POST /tendermint.abci.ABCI/VerifyVoteExtension`

## Request body

- TendermintAbciRequestVerifyVoteExtension
  - `hash` string, byte
  - `height` string, int64
  - `validator_address` string, byte
  - `vote_extension` string, byte

## Response `200`

A successful response.

- TendermintAbciResponseVerifyVoteExtension
  - `status` 'UNKNOWN' | 'ACCEPT' | 'REJECT' — - REJECT: Rejecting the vote extension will reject the entire precommit by the sender. Incorrectly implementing this thus has liveness implications as it may affect CometBFT's ability to receive 2/3+ valid votes to finalize the block. Honest nodes should never be rejected.

## Other responses

- `default` — An unexpected error response.
