How to Create LN Markets API Keys for Beet Robot
Step-by-step guide to creating LN Markets API keys with the right permissions so Beet Robot can trade on your behalf — without ever touching your funds.
Before Beet Robot can place or manage trades, it needs access to your LN Markets account through API keys. This guide walks you through creating a key with exactly the permissions the bot needs — nothing more, nothing less.
Security first: Beet Robot only needs
futures:isolated:readandfutures:isolated:writeplus a few read-only account permissions. It never requires withdrawal access, so your funds stay safe even if a key is ever compromised.
Step 1 — Open the API Keys section
Log in to LN Markets, click the account menu in the top-right corner, and select API keys.
Step 2 — Create a new key
On the API keys page, click + New key.
Step 3 — Name the key and set a passphrase
Give the key a memorable name (e.g. Beet Robot) and choose a strong passphrase.
Important: The passphrase is only known to you — LN Markets does not store it. If you lose it, you will need to delete the key and create a new one. Write it down somewhere safe before continuing.
Step 4 — Set the correct permissions
Select the following permissions. These are the minimum required for Beet Robot to operate:
| Permission | Why it's needed |
|---|---|
account:read |
Check balance and account information |
account:deposits:read |
View deposit history (read-only) |
account:withdrawals:read |
View withdrawal history (read-only) |
account:notifications:read |
Read account alerts |
futures:isolated:read |
View open and closed positions |
futures:isolated:write |
Place and cancel limit orders |
Do not enable account:write, account:deposits:write, account:withdrawals:write, futures:cross:*, or synthetic-usd:write. Beet Robot does not need them, and keeping them off limits the blast radius if anything goes wrong.
Step 5 — Copy and store the credentials
After clicking Create, LN Markets shows you the key, secret, and passphrase once. Copy all three somewhere secure before closing the page.
You won't be able to see the secret again. If you close this page without copying it, you'll need to delete the key and start over.
Step 6 — Paste the credentials into Beet Robot
Head to the Settings page in Beet Robot, find the LN Markets connection section, and paste your API Key, Secret, and Passphrase into the corresponding fields. Select Mainnet (or Testnet4 if you're testing).
That's it — Beet Robot will verify the connection and start trading on your next scheduled tick.
Troubleshooting
"Invalid API key" error — double-check that you copied the key and secret without extra spaces. The secret is base64-encoded and sensitive to whitespace.
"Insufficient permissions" error — return to the LN Markets API keys page, edit the key, and ensure futures:isolated:write is checked.
Lost your passphrase — delete the existing key on LN Markets and create a new one following this guide.
