The Onboarding API is only to be used by partners to Walley that conduct their own AML/KYC process and agreements with merchants. These self-onboarded merchants are referenced as sub-merchants. A separate agreement between the partner and Walley will need to be in place before access is allowed to this API.
The partner initiates the setup of a merchant by performing a request against the Onboarding API with the details needed. Walley will automatically setup all the things needed to be able to start receiving payments from end customers.
One Merchant can have several sub-stores that is used to distinguish selling market and type of store like B2B and B2C.
