Authentication

Sezzle uses scoped API keys to allow access to the API. You can find/generate these keys on your merchant dashboard once you have been approved by Sezzle.

Once you have a valid token, it must be used as a Header for subsequent requests to our API, using the format below.

Example Payload​

{
  "public_key": "example-public-key",
  "private_key": "example-private-key"
}

caution

You must replace the token you obtain from the Authentication endpoint every 120 minutes. However, we do not restrict you to a single token, and you can obtain a new one at any time.

  "expiration_date": "2017-01-01T01:30:25.388940303Z",
