How to connect to Testnet on Blockfrost API with blockfrost-js

Question

I am getting an error connecting to the Blockfrost API with blockfrost-js

"Network token mismatch. Are you using token for the correct network? See https://docs.blockfrost.io/#section/Available-networks."

I went to blockfrost.io and requested a API key for the testnet, but I still have this error. What to do?

Answer 1

To connect to the Testnet with blockfrost-js initialize it like this:

const API = new BlockFrostAPI({
  projectId: 'YOURAPIKEYFORTESTNET',
  isTestnet: true
});
