      description: "Create and update external payments.<br><br>The set of attributes to send in the request body may vary based on the account configuration. Please contact the implementation specialist for more information.<br><br>\nThe request schema for posting a payment for a single invoice is slightly different than that for posting a payment for multiple invoices.\n\nFor instance, sample request for posting payment for a single invoice looks like:\n```\n{\n  \"identifier\": \"PMT0010-05\",\n  \"invoice_number\": \"INV1234-01\",\n  \"amount\": 10000,\n  \"currency\": \"usd\",\n  \"date\": \"2018-01-10\",\n  \"customer_identifier\": \"C1234\",\n  \"customer_name\": \"Acme Inc.\",\n  \"notes\": \"Notes\",\n  \"ref1\": \"1234\",\n  \"ref2\": \"PO# 84767\"\n}\n```\n\n*Note: Customer will be created using the customer_&ast; attributes if it doesn’t already exist at the time of payment import.*\n"
