Retrieve a one-time charge using its unique identifier, chargeId (e.g., 28936112-bcf1-4240-a851-85fb087c282a). This ID can be found at the end of the URL when the charge is created.
If the charge has been paid, transaction details will appear under the paylinkTx field in the response. If no transaction has occurred yet, the field will be returned as "paylinkTx": null.
