Créer une session
Initiate a Sezzle session with shopper order details, redirect links, and capture and tokenization settings. A session must carry an order, tokenize a customer, or both. Omit the order and set customer.tokenize to true for standalone tokenization, which returns tokenize.approval_url instead of an order.

The HTTP request information used to redirect the customer upon completion of the session. Required for sessions that include an order and use redirect checkout, and for any session that tokenizes a customer — including standalone tokenization, where it is the destination the customer returns to after approving.
The HTTP request information used to redirect the customer in the case of a cancellation. Required for sessions that include an order and use redirect checkout. Optional for standalone tokenization sessions, which have no order to cancel — supply it only if you want a separate destination for customers who decline.
Customer details for this session. To optimize checkout and boost conversion, it is recommended to include as much customer information as possible.

Merchants enrolled in Sezzle's Long Term Lending program (as well as general integrations) must send a Customer object that includes, at a minimum, a complete and valid shipping_address object.

Tokenizing a customer allows you to authorize future transactions on their behalf. If omitted, will default to false. To create an order and tokenize a customer in a single session, set customer.tokenize to true and provide an order object. The user will be prompted to accept tokenization during checkout. To tokenize a customer without a purchase (standalone tokenization), set customer.tokenize to true and omit the order object. The response returns tokenize.approval_url to redirect the customer to. Standalone tokenization is enabled per merchant — contact your account manager.
Indicates whether the tokenization is part of a recurring subscription. true - The token is associated with a subscription and will be reused for future charges. false - The token is for a one-time use, such as Pre-order or Single Tokenization.
Order ID, amount, and capture intent. Order details optional.

This token represents the merchant request to tokenize a customer. This token can only be used one time. Once a user accepts/denies tokenization, this token and its approval URL will be obsolete.
The expiration of the request token in ISO 8601 date/time format.
The URL for the user to accept tokenization. This URL does not create an order and the customer is not charged; it is only used for tokenizing a customer. Returned only for standalone tokenization — a session with customer.tokenize set to true and no order object — and only for merchants who have standalone tokenization enabled. It is omitted for sessions that include an order, where the customer authorizes tokenization during checkout instead. The URL expires 30 minutes after the session is created, which is sooner than the expiration field above. Create the session at the moment the customer clicks to authorize.
