Post the invoice

Now that we have the request we can post it via the Create Invoice endpoint.Congrats! You’ve created your first invoice!

Paying an invoice

This section will walk you through posting a payment to an invoice.

Get a Journal & Transaction

We need to get a transaction id to reference in the payment.You have two options for this:

Assembling the payment

Now that we have a transaction id, we can create our payment request body.Payments that don’t use the full amount of a transaction will bump out a new line of the journal based on the referenced transaction.

You can apply multiple transactions to an invoice at the same time. Each transaction will be a separate payment.

Field	Description	Example
`transaction_id`	ID from transaction	`"1234"`
`amount`	Payment amount	`10000`
`account`	ID from account (If you want to categorize the transaction at the same time)	`"1234"`

Example request body:

{
    "transactions": [
        {
            "transaction_id": 21069178,
            "account_id": "2550",
            "amount": 8999.99
        }
    ],
}

Post the payment

Now that we have the request we can post it via the Create Payment endpoint.Congrats! You’ve paid your invoice!
