A Charge represents a single payment transaction. Use a Charge to either authorize an amount and capture it later, or authorize and capture payment immediately.
Depending on the integration pattern, you can either create a Charge using a valid Charge Permission, or create it as a result of a successful Checkout Session. A successful Charge will move from Authorized to CaptureInitiated to Completed state. The Authorized state may be preceded by a Pending state if you set canHandlePendingAuthorization to true, or payment was captured more than 7 days after authorization. See asynchronous processing for more information. An unsuccessful Charge will move to a Declined state if payment was declined, and move to a Canceled state if the Charge is explicitly canceled, or the Charge expires after 30 days in the Authorized state.

Note: If your publicKeyId has an environment prefix (for example: SANDBOX-AFVX7ULWSGBZ5535PCUQOY7B) follow these instructions instead.

Operations
Create Charge
You can create a Charge to authorize payment, if you have a Charge Permission in a Chargeable state. You can optionally capture payment immediately by setting captureNow to true. You can create up to 25 Charges per one-time Charge Permission.
The response for Create Charge will include a Charge ID. This is the only time this value will ever be returned, so you must store the ID in order to capture payment, Get Charge details, or Create Refund at a later date. If the request fails, you should reengage the buyer and ask them to go through checkout again.

Capture payment on a Charge in the Authorized state. A successful Capture will move the Charge from Authorized to Captured state. The Captured state may be preceded by a temporary CaptureInitiated state if payment was captured more than 7 days after authorization. See asynchronous processing for more information. An unsuccessful Charge will move to a Declined state if payment was declined.
