Request Transaction Signing

The BindID transaction signing request initiates a flow that requests approval for a transaction and then authenticates the user. You can invoke a transaction signing process by calling the /authorize_ciba endpoint with a bindid_psd2_transaction claim. For example, when a user calls their bank to approve a large money transfer, the bank can initiate the transaction request by SMS:
