When your program is ready to go live on the Solid platform, it needs to be configured with different payment types enabled or disabled and with various transaction limits for each payment type. The program config is primarily used to set Account Transaction Limits for each account that is created under the program.
Solid's customer success manager will work you the FinTech program to provide the config spreadsheet and set up the program config before going LIVE.
You can view a sample of the Solid – FinTech Program Config spreadsheet here.
