Do you like what you see? If you want to achieve the same level of integration of btcpayserver into your S4HANA Development system, you need to follow these steps:

1. Setup a btcpayserver instance (https://btcpayserver.org/) This is a free and open source payment processor software - no third party involved!

   • btcpayserver comes with a bitcoin fullnode, a lightning node and a Store

2. Configure your btcpayserver and make it reachable via the internet. Configure the following list:

   • a Store on your btcpayserver (this is important for the API calls)
   • a bitcoin wallet
   • a lightning wallet / node
   • bitcoin and fiat exchange rate source (in my case, Kraken)
   • the checkout appearance (in my case, in the look of SAP)
   • an admin user and a API key (you can setup a dedicated "read only" and "create invoice"-only technical user with an API key for extra security)
   • depending on your setup:
     • give it an URL via your DNS provider (important for the Destination settings in SAP environment)
     • a certificate for secure https connection (important for the transaction STRUST in your SAP environment)
     • take care of your firewall within SAP (create an exception rule for your btcpayserver, so the SAP connection can be established)

3. Within your SAP environment, take the following steps:

   • create a Destination to your btcpayserver in t-code SM59

   • import your ssl-certificates into t-code STRUST and distribute it with t-code SMICM

   • create a package in SE80

   • create two database tables with the following fields Name: YTABINVOICE Name:ZTABINV

   • Import the program main code Z_BITCOIN (insert your individual information where needed (Destination in t-code SM59, the URL, and StoreIDs))

   • Import the function module for the price Z_GET_PRICE (Destination in t-code SM59, the URL, and StoreIDs)

   • take care of the naming of the fields

4. Test it!
