Activates a physical card ordered via bulkOrderCard, linking it to a customer account and optionally creating a new customer if one doesn't exist.
If needed, a PIN can be set during activation. All operations are atomic—any failure rolls back the entire operation.
After receiving their card, the cardholder is to call this endpoint to register an account in UnDosTres and activate the card.
Also, you can activate several cards for the same account in case of enterprise users creation.
You will provide customer_id in the request body, it will associate the new card with the existing customer.
Accounts with a Composite Balance can also use this endpoint to register and activate their accounts.
You can learn more about these accounts here: Composite Balance
Example 1: Only customer_id provided
customer_id provided{
"customer_id": "12345678",
"card_identifier": "CARD-001",
"reference_batch": "7e4b85e27c4610824900af48f340394d"
}Example 2: When using Composite Balance (only for Credit Engine)
In case of a Composite Balance, a parameter balance is required.
It must be an object containing the balance identifier.
