Here in below description, ‘Client’ means the organization which is implementing Contis API.
Contis API service notifies the client about 3DS OTP for consumer to authenticate online card transaction. Client should notify consumer via consumer’s preferred delivery option email or SMS.
The client must integrate the call back URL in the Contis API service to receive notifications. If client does not prefer to configure URL then Contis could send 3DS OTP to consumer directly on behalf of client.
