API to generate vanilla and subscription payment links.

Payment Status

Once your customer completes a payment, the redirect URL will be appended with the following params
- createdAt: The date the charge was captured at
- paymentLinkId: The payment link id
- status: indicates the payment status, whether captured or failed
- transactionId: The transaction / charge id related to the payment

You may also get notified about a payment's status by setting up a webhook. Details [here](https://mamopay.readme.io/reference/post_webhooks)

A third approach to check the transaction status is by calling our transaction info API [here](https://mamopay.readme.io/reference/get_charges-chargeid)
