API access is only available on the Pro and Agency plans. If you have an Essentials account, you will need to upgrade to Pro to access the API. To use this API you will need a valid API Key. You can generate an API key on your account page. Your API key needs to be sent with every request in the authorization header:
"Authorization": "Bearer <token>"
The Paperform API is rate limited to prevent abuse. If you exceed the rates, you will see a response of
429 Too Many Requests. You can monitor your current usage and limits via the following response headers.
Request limit per minute.
The number of requests left for the time window.
How many seconds to wait before the limit has lifted.
Unix timestamp for when the limit will lift.
