Touch points are different channels/medium through which transactions or inquiries can be performed by OBAPI user or Third Party Applications. For e.g. Mobile Application, Internet, Siri/Chatbot, etc. are different internal touch points through which OBAPIs can be accessed whereas Yodlee, which is a third party provider can be configured an external touch point, and can access OBAPIs on behalf of the user (provided user consent is in place).
OBAPI enables the Banks to define touch points, map transactions to roles for each touch point and help user in managing fine grained consents for each third party application.
