Initiate verification

Introduction

Initiate verification is initiated through HTTPS POST request by using URLs and the parameters.

To initiate card verification, Connecting Party’s app sends {accessToken} with other device parameters to Connecting Party’s server. These parameters are used to start a session with unique random {nonce} and encrypted {signature}. In response Connecting Party’s server also provides information about {invoiceId} in Connecting Party’s system and {endpointId} in Billblend.
