# Forget **DELETE /byron-wallets/{walletId}/transactions/{transactionId}**
status: stable
Forget pending Byron transaction. Importantly, a transaction, when sent, cannot be cancelled. One can only request forgetting about it in order to try spending (concurrently) the same UTxO in another transaction. But, the transaction may still show up later in a block and therefore, appear in the wallet. ## Servers - https://localhost:8090/v2: https://localhost:8090/v2 () ## Parameters #### Path parameters - **walletId** (string(hex)) - **transactionId** (string(hex)) ## Responses ### 406: Not Acceptable #### Body Parameters: application/json (object) - **message** (string) May occur when providing an invalid 'Accept' header. - **code** (string) ### 403: Forbidden #### Body Parameters: application/json (object) - **message** (string) Occurs when attempting to delete a transaction which is neither pending nor expired. - **code** (string) - **info** (object) ### 404: Not Found #### Body Parameters: application/json (object) - **message** (string) May occur when a given walletId does not match with any known wallets (because it has been deleted, or has never existed). - **code** (string) - **info** (object) ### 204: No Content [Powered by Bump.sh](https://bump.sh)
