Objective
This article helps you turn on PCI mode for your account so that sensitive payment details captured with Programmable Voice and <Pay> are redacted, which is required if you build PCI payment workflows on Twilio Voice.
Product
Programmable Voice
Environment
Twilio Console
User Account Permission/Role(s) Required
Update access to Voice settings is required. Without it the Enable PCI mode button is not shown.
Procedure
- In the Twilio Console, select Communications in the left sidebar.
- Select Voice, then Settings.
- On the General tab, select Payments in the settings navigation.
- Under PCI mode, check the Status field. It reads Disabled if PCI mode is not yet on.
- Read the section description, including the note that once PCI Mode is enabled it cannot be disabled for that account.
- Select Enable PCI mode.
- In the Enable PCI Mode dialog, select the acknowledgement checkbox to confirm you accept the terms.
- Select Save. The dialog closes, a confirmation message reads "Settings Updated", and the Status field now reads Enabled.
Additional Information
- Enabling PCI mode is permanent. Once it is on, the Enable PCI mode button disappears and the setting cannot be turned off from the Console.
- The acknowledgement checkbox is required. Selecting Save without it shows the validation message "Enable PCI Mode is required" and the dialog stays open. Selecting the checkbox clears the error.
- Select Cancel to close the dialog without enabling PCI mode. The status stays Disabled.
- With PCI mode enabled, call recordings are stored automatically when recording is enabled on your PCI workflow. To transcribe those recordings you must use the Voice
<Transcription>noun — native and Marketplace transcriptions are not available while PCI mode is on. - If the change cannot be applied, an error message reads "Error Updating Settings" — retry the save.
- Twilio's Responsibility Matrix and the Programmable Voice documentation, linked in the section description, explain your obligations when using Programmable Voice in a PCI workflow.
