Hi I’m looking to sign an fcl transaction from my backend server that looks something like this:
const result = await fcl.send([
fcl.transaction`${BUY_NFT}`,
fcl.args([
fcl.arg(params.nftId, fcl.t.UInt64),
fcl.arg(params.contractAddress, fcl.t.Address),
]),
fcl.proposer(proposer),
fcl.authorizations(authorizations),
fcl.payer(payer),
fcl.limit(9999),
])
.then(fcl.decode);
However, I am not sure how to configure the proposer/authorizer/payer without having a wallet connected from a frontend.
Any help would be greatly appreciated. Thank you
