The WL FS merchant contract API enables retrieval and updating at site & terminal level. Access to contract data is restricted to your acquirer and own merchant contract identifiers. For third parties, contract updating is limited depending on the generic user role (e.g. PSP, PayFac, Merchant) limitations agreed with the acquiring bank.

Version note:
Please be aware that these API interfaces may be changed and improved (e.g. addition of fields).

The "Try out" feature does not work at this time because the sandbox is being improved to support new functionality.
