Quick start

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. Here's an example of how straightforward it can be:

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 added here, such as phoneNumber, email etc.

    },

    // Additional customer-level information will go here

  },

  "items": [

    {

      "articleNumber": "10",

      "description": "Product A",

      "quantity": 2,

      "unitPriceExcludingVat": 199.99,

      "vatPercentage": 25

      // Support for more fields like costCenter, additionalDetail, etc., if relevant

    }

  ],

  "deliveryType": "EINVOICE",

  "draft": false,

  "sendInvoice": true

}'

What Happens Next?

Once this example request is sent:

1. The invoice is created in real-time and returned inte the API Response
2. The invoice is distributed immediately (if sendInvoice=true and draft=false) as an e/EDI-invoice.

With just these components, you can send a ready-to-use invoices to your customer and get paid. For advanced use cases, continue with the following guide on coming pages or explore our full API documentation right away.
