Overview

**Use this API to initiate a payment.**

When you create a payment, it is stored with GreenBanana. At this stage, the payment intent is generated but requires confirmation from either the user or merchant to proceed.

Once confirmed (by including confirm=true and payment_method), the request is sent to the selected BNPL provider to verify if the customer is eligible for credit to proceed with the Buy Now, Pay Later (BNPL) provider.

The following request body example demonstrates how to create a payment with GreenBanana, which can be processed through any BNPL provider.

**Note:** The `metadata` field is used to carry additional information required by the BNPL provider. We have compiled all necessary metadata fields to ensure compatibility with any BNPL provider.

Payments - Create

**Use this API to confirm the payment and forward it to the BNPL provider.**

Alternatively, you can confirm the payment directly in the *Payments/Create* API by setting `confirm=true`. After confirmation, the payment may result in one of the following outcomes:

Once payments confirm is successfully completed, we will have payment status as `requires_capture` or `succeeded` indicating the amount for customer is authorized by the BNPL provider

1. **Fail** with a `failed` status.
2. **Transition** to a `requires_customer_action` status, along with a `next_action` block.
3. **Succeed**, with either:
- `succeeded` (for automatic capture), or
- `requires_capture` (for manual capture).

`BNPL providers typically use methods like `manual_capture` or `manual_multiple_capture` for capturing payments, as specified in the Payments Create request.

You can configure routing rules to process specific payments through specific connectors. If you would like to route a specific payment with specific connector you can also pass
"connector": ["connector_name"] to process the payment.
