B2B Invoicing - Quickstart

Get up and running in no time

With Payer's Invoice API, generating and sending an invoice is as simple as making one HTTP POST request.

curl --request POST \

 --url 'https://b2b.payer.se/api/v3/invoices' \

 --header 'Authorization: Bearer {token}' \

 --data '{

  "invoiceCustomer": {

    "address": {

      "companyName": "ABC Corp",

      "emailAddress": "customer@example.com",

      "streetAddress1": "123 Main Street",

      "zipCode": "12345",

      "city": "Stockholm",

      "countryCode": "SE"

      // Additional fields is be added here, such as phoneNumber, email etc.

    },

    // Additional customer-level information can go here

  },

  "items": [

    {

      "articleNumber": "10",

      "description": "Product A",

      "quantity": 2,

      "unitPriceExcludingVat": 199.99,

      "vatPercentage": 25

      // Add more fields like costCenter, additionalDetail, etc., if needed

    }

  ],

  "deliveryType": "EINVOICE",

  "draft": false,

  "sendInvoice": true

}'
