Payment Resource
Agent Assisted Payments
Introduction
Agent assisted payments allow agents to collect customer payment information in a PCI-compliant manner on Twilio voice calls in the contact center. With agent assisted payments, the agent stays on the phone and guides the customer through the payment flow, requesting required various pieces of payment information one item at a time.
The agent can control the payment flow asking for payment information in the order they see best for the customer and even re-request information as needed. When the customer is inputting their payment information, the agent will not be able to hear the DTMF (dual tone multi frequency), ensuring the security of the payment information and the customer.
Once the agent has all the information they need, they complete the payment and Twilio sends to the connector for processing.
Workflow
- Agent requests some information, including payment method, from the customer and begins a Twilio Pay session
- Agent triggers API calls (through their UI) to collect specific pieces of payment information from the customer (e.g., credit card number, expiration date, bank account number)
- Caller enters the requested payment information via DTMF. Agent is not able to hear any DTMF that the customer enters.
- Once the customer is done, the agent sees the result of the customer’s input (e.g., xxxx xxxx xxxx 4242 or “invalid-card-number”)
- Agent requests the next piece of required payment information and continues to do so, until all the information needed is entered
- The agent is able to re-request a piece of payment information as needed in any order and at any point during the flow
- The agent is also able to cancel the payment at any point during the flow
- Once all the information is collected, the agent completes the Pay session and receives the result of the payment e.g., success
API design
Agent collects and enters information like payment method, charge amount, or token type and then starts the pay session. Then the agent calls the Update API (through their own UI) for each piece of payment information. Once all the required payment information is collected through the Update API, the Agent then completes the pay session by setting the status to complete
, which then processes the payment and completes the transaction. The agent can also cancel the <Pay> session by setting the status to cancel
.
Resulting information will be delivered via status callbacks.
