How to set up a Blink wallet

This is a minimal guide to set up Blink (ex Bitcoin Beach Wallet) account as a funding source for the LightningATM.
Get more info and download the app from blink.sv. To learn more about the API visit dev.blink.sv or discuss on the Galoy Mattermost.

Get the credentials from the Blink Dashboard

  • open the Blink Dashboard
  • log in with your email or phone number if you are using Blink already
  • if you have no account yet can create a new one by logging in with a phone number

Wallet ID

  • once logged in to dashboard find the wallet IDs under the balances

    wallets

  • copy the BTC wallet ID to pay out from the BTC balance

  • copy the USD wallet ID to pay out from the Stablesats balance

  • paste the wallet ID into the config.ini file under the [blink] section

API key

  • create a new key on the API Keys tab

  • give it a name and choose a Scope which permits to send payments (Read and Write)

  • the default expiry is 90 days

    api_key

  • copy the key (starting with blink_ ) and paste it into the config.ini file under the [blink] section

Set the config.ini file

  • in the [atm] section set the activewallet to blink

    activewallet = blink

  • in the [lnurl] section set the lnurlproxy to active

    lnurlproxy = active

  • the [blink] section must include these:

    [blink]
graphql_endpoint = https://api.blink.sv/graphql
wallet_id = 5dxxxxxxxxxxxxxxxxxxxxx
api_key = blink_xxxxxxxxxxxxxxxxxxxxxxxxxxxxx

  • A complete example of a config.ini using the pocket version of the ATM without a button with USD coins:

    [atm]
cur = usd
centname = cent
language = "en"
camera = False
fee = 0
dangermode = on
display = waveshare2in13v2
activewallet = blink
payoutdelay = 10

[lnurl]
lnurlproxy = active
lnurlproxyurl = https://api.lightningatm.me/v1/lnurl

[btcpay]
url =

[lnd]
macaroon =
verify = on

[lntxbot]
url =
creds =

[lnbits]
url = https://legend.lnbits.com/api/v1
apikey =
method = lnurlw
timeout = 90

[blink]
graphql_endpoint = https://api.blink.sv/graphql
api_key = blink_xxxxxxxxxxxxxxxxxxxxxxxxxxxxx
wallet_id = 5dxxxxxxxxxxxxxxxxxxxxx

[coins]
coin_types = 2,0.01,1  usd cent
            3,0.05,5 usd cent
            4,0.10,10 usd cent
            5,0.25,25 usd cent
            6,1.00,1 usd

Notes

  • remember to top up the funding wallet with some sats
  • easiest to monitor the payouts if you are logged in to the Blink app on your phone
  • be aware when testing that paying the same account is not allowed (cannot withdraw from the LightningATM to the same account from which the credentials are used)
  • note the date of the expiry of the API key (valid for 90 days by default) and create a new one before the ATM stops working
