How to get keypair for API Authorization

estherlinlin commented 2 years ago

Problem

Our team is developing maker-app base on this repository. Currently we are migrating update and transfer hotspot features from helium-app, but encounter an issue 401 authorization fail, when calling API from wallet endpoint https://wallet.api.helium.systems/api

status:401 message: POST url:https://wallet.api.helium.systems/api/transactions]

We need keypair to generate token for the Authorization header in api request, (keypair are also needed when calling transaction APIs) but we only could retrieve walletLinkToken when user sign in by linking helium account.

How can we get the keypair for API authorization and transaction signing? Or is there a way to get keypair from walletLinkToken?

export const createKeypair = async (
  givenMnemonic: Mnemonic | Array<string> | null = null,
) => {
  ...
  const { keypair: keypairRaw, address } = await Keypair.fromMnemonic(mnemonic)

  await Promise.all([
    setSecureItem('mnemonic', JSON.stringify(mnemonic.words)),
    setSecureItem('keypair', JSON.stringify(keypairRaw)),
    setSecureItem('address', address.b58),
  ])
}

export const getKeypair = async (): Promise<Keypair | undefined> => {
  const keypairStr = await getSecureItem('keypair')
  if (keypairStr) {
    const keypairRaw = JSON.parse(keypairStr)
    return new Keypair(keypairRaw)
  }
}

We found the solution in the latest update. Thanks! 🙏 The flow of transfer hotspot and assert location has changed by submitting the transaction on helium official hotspot app, it seems that it is not allowed to go through whole transaction only by maker app.
