Modification

Aside from the card lifecycle and options, Treezor offers a series of features to manage your cards on the day-to-day basis.

Feature	Description
Lock/Unlock	Ability to update the card status, hence unlocking and locking the card temporarily or permanently.
PIN code	Ability to change the PIN code, or unlock a card which has been blocked due to erroneous PIN code entries.
CVV unlock	Ability to unblock a card which has been blocked due to erroneous CVV entries.
Regeneration	Ability to recreate the virtual card image if your branding changes for instance.

Block a card

If you suspect fraud or misuse, the API allows you to block temporarily or permanently a card, effective immediately.

This feature can also be used with special cards that must expire at a specific date (such as a one-year valid gift card). You will have to lock the card on the expiration day.

Best practice – Allowing your end users to block their cards

While blocking a card temporarily is no issue, you should not allow end users to block their cards permanently without thorough confirmation steps (as fees may apply to issue a replacement card).

Card Status

Statuses are defined in the statusCode attribute of a Card.

Code	Plaintext value	Description	Locked
`0`	`UNLOCK`	The card is unlocked and can be used (if no other options or limits prevent it)	N/A
`1`	`LOCK`	The card is locked and cannot be used	Temporarily
`2`	`LOST`	The card is lost and cannot be used	Permanently
`3`	`STOLEN`	The card is stolen and cannot be used	Permanently
`4`	`DESTROYED`	The card is terminated and cannot be used	Permanently
`5`	`LOCK_INTERNAL`	The card is locked by Treezor and cannot be used, only Treezor is able to unlock it.	Temporarily
`6`	`EXPIRED`	The card has expired because it has been renewed or its expiry date has passed. The following webhooks are sent: `card.expiryAlert` – The card expires at the end of the next month for you to anticipate Renewal. `card.update` – The card expired.	Permanently

Caution – A lost or stolen card can't be reactivated

If the cardholder wants a replacement card, a new card will have to be ordered.

Request example

You can use the following request to change the card lock status, with the cardId as a path parameter and the lockStatus in the body.

CURL

bash

curl -X PUT {baseUrl}/v1/cards/{cardId}/LockUnlock
	--header 'Authorization: Bearer {accessToken}' \
	--header 'Content-Type: application/json'

Here is an example of {payload} which specifies a lockStatus of 2, declaring the Card as LOST and locking it permanently.

JSON

json

{
	"lockStatus":2
}

Returns a Card object, with a statusCode attribute set to either UNLOCK, LOCK, LOST, STOLEN, DESTROYED.

JSON

json

{
	"cardId": 999894949,
	"userId": 100198207,
	"walletId": 2728965,
	"publicToken": "105603415",
	"cardTag": "string",
	"statusCode": "LOST",
	"isLive": 1,
	"cancellationNumber": "19532590" 	// Generated for LOST & STOLEN Cards only
	// [...] some attributes are hidden
}

Although you provide the lockStatus as an integer, it is returned as a plaintext value.

Treezor also sends a card.lockunlock webhook.

PIN Change

If a Card is in the UNLOCK status and not PIN-locked, you can change its PIN code. There are 2 ways to proceed:

Context	Endpoint	Usage
Without the previous PIN	`/v1/cards/{cardId}/setPIN`	Machine-oriented
Requiring the previous PIN	`/v1/cards/{cardId}/changePIN`	End user-oriented

Once set, you cannot retrieve a PIN code using the Treezor API. Unless you are PCI/DSS compliant, you shouldn't store the PIN code on your infrastructure either.

End user manual action required

When a PIN code is changed via the API, there is no immediate way to relay the information to the physical card. A withdrawal or balance inquiry must be made by the cardholder to an ATM for the change to take effect.

The ATM automatically updates the PIN code of the Card upon such as operation. Note that even a rejected withdrawal will update the PIN code.

If your Card program doesn't allow for withdrawals, you should not allow or change PIN codes, as end users would be unable to physically use their cards.

Without the previous PIN

This is the initial situation upon Card creation.

Parameters

In addition to the cardId passed as a path parameter, the following parameters are required.

Attribute	Type	Description
`newPIN`	string	The new PIN code of the card. Must be a string to allow for leading zeroes.
`confirmPIN`	string	Confirmation of the new PIN code of the card. Must be a string to allow for leading zeroes.

CURL

bash

curl -X PUT {baseUrl}/v1/cards/{cardId}/setPIN \
	--header 'Authorization: Bearer {accessToken}' \
	--header 'Content-Type: application/json' \ 
	-d '{payload}'

Here is an example of {payload}:

json

{
	"newPIN":"1234",

    ]
}

It is recommended that you let your end user choose their PIN when ordering a new Card.

PIN Unlock

Entering 3 erroneous PIN codes in a row blocks the PIN and sets the pinTryExceeds to 1.

As the card is blocked on the server side, you can unblock it instantaneously using a dedicated endpoint. When unlocking a PIN, the PIN code remains unchanged.

Note – You can't change a locked PIN

If the PIN is blocked you must unlock the PIN before being able to change it.

Request example

Only the cardId passed as a path parameter is required to use the following request.

CURL

bash

curl -X PUT {baseUrl}/v1/cards/{cardId}/UnblockPIN \
	--header 'Authorization: Bearer {accessToken}' \
	--header 'Content-Type: application/json'

Returns a Card object and sends a card.unblockpin webhook with the pinTryExceeds parameter set to 0.

CVV Unlock

The Card CVV can get locked if the cardholder enters multiple times in a row an erroneous CVV while attempting an e-commerce payment. The number of attempts is configurable, and is usually set to 3 or 5.

When this happens, the cardtransaction.create webhook contains an authorizationNote valued to DR: CVC2 tries exceeded.

As the card is blocked on the server side, you can unblock it instantaneously using a dedicated endpoint.

CURL

bash

curl -X PUT {baseUrl}/v1/cards/{cardId}/unblockcvc2 \
	--header 'Authorization: Bearer {accessToken}' \
	--header 'Content-Type: application/json'

Danger – Do not expose this endpoint to your end users

This endpoint is only dedicated to you, and you must ensure the cardholder's identity before unlocking the card.

It returns a 204 HTTP response with the following description: successfully unblocked.

Tip – Unlocking for users not using Connect

If you haven't migrated to Connect, or if the feature is not yet available to you, you must open a ticket to unlock a CVV.

3DS Unlock

The 3DS feature of a Card can get locked if the cardholder fails 3 times the 3DS authentication using One Time Password while attempting an e-commerce payment.

When using the Strong Customer Authentication instead of One Time Password, a failure to authenticate doesn't increment the 3DS failure count and will not lock the 3DS feature.

If the SCA feature cannot be used and the fallback to One Time Password via SMS is used, then a locking can still occur.

To unlock the 3DS feature, you must open a ticket as no API endpoint currently allow to unlock the 3DS feature.

Regeneration

In case your brand changes its graphical identity (such as a new logo, new colors, new layout, etc.) you can ask Treezor to set up a new card design, and then re-generate Virtual Cards images without altering their actual PAN, CVC, or expiration date.

Example of a Card regeneration:

CURL

bash

curl -X PUT {baseUrl}/v1/cards/{cardId}/Regenerate \
	--header 'Authorization: Bearer {accessToken}'

Returns the Card object and sends a card.regenerate webhook.
