tryExecuteSirenAction

tryExecuteSirenAction<R>(actionName: string, __namedParameters: object): Promise‹AxiosResponse‹R››

Defined in src/swap.ts:147

Low level API for executing actions on the Swap.

If you are using any of the above actions (Swap.redeem, etc) you shouldn't need to use this. This only performs an action on the CND REST API, if an action is needed on another system (e.g blockchain wallet), then the needed information is returned by this function and needs to be processed with doLedgerAction.

throws A Problem from the cnd REST API, or WalletError if the blockchain wallet throws, or an Error.

Type parameters:

R

Parameters:

actionName: string

The name of the Siren action you want to execute.

__namedParameters: object

NameType
maxTimeoutSecsnumber
tryIntervalSecsnumber

Returns: Promise‹AxiosResponse‹R››

The response from Cnd. The actual response depends on the action you executed (hence the type parameter).
