Study Notes

Visa Token Service (VTS) Process Flow

VTS sends a "Token Created" notification to the Issuer when a token is created.
Visa sends a "Token Provisioned" notification to the Issuer when the token is provisioned.
The Provision Token API is used to submit card details to VTS in exchange for a token and other payment-related data.
- Endpoint: POST - /vts/provisionedTokens?apiKey={apikey}
- Input: clientAppId, panSource, accountType, clientWalletAccountId, encPaymentInstrument, presentationType
- Output: vProvisionedTokenID, vPanEnrollmentID, encrypted token info

Get Card Metadata & Content

TR retrieves card metadata and content resources using the PAN enrollment ID obtained previously.
Visa returns corresponding card metadata and content GUIDs to TR.
TR sends a getContent call to VTS based on the obtained GUIDs, and VTS returns the actual content resources, which TR must cache locally.
Get Card Meta Data API:
- Endpoint: GET - /vts/panEnrollments/{vPanEnrollmentID}?apiKey={apikey}&platformType={platformType}
- Input: platformType: iOS|ANDROID|WINDOWS|WEB
- Output: Card Metadata (e.g., backgroundColor, labelColor, etc.), Card element GUIDs
Get Content API:
- Endpoint: GET - /vts/cps/getContent/{guid}?apiKey={apikey}
- Input: guid
- Output: Base64 encoded content data, mime type, dimensions, etc.

Get Payment Data for Transaction

TR requests payment data for a transaction using the provisioned token ID.
Visa Token Service returns a cryptogram (TAVV) to be used for each transaction.
Get Payment Data API:
- Endpoint: POST - /vts/provisionedTokens/{vProvisionedTokenID}/paymentData
- Input: vProvisionedTokenID
- Output: TAVV cryptogram

Card Metadata Change Notification

Issuer updates card metadata via issuer tools.
VTS sends a card metadata change notification to TR.
TR sends a card metadata retrieval request to VTS to get the updated card metadata information.
Notification API – Card Metadata:
- Endpoint: POST /panMetadata?apiKey={apikey}
- Input: vPanEnrollmentId, datetime
- Output: updated card metadata information
