Authentication

You'll need to authenticate your requests to access any of the endpoints in the FastPDF API. In this guide, we'll look at how authentication works. FastPDF offers a single way to authenticate your API requests: token authentication.

Validating your token

When establishing a connection to all FastPDF API endpoints, you will need your access token — you will find it in the FastPDF profile under API settings. Here's how to add the token to the request header using cURL:

Required attributes

curl -X GET https://data.fastpdfservice.com/v1/token \
  -H "Authorization: Bearer {token}"

The above command should display Valid token in your terminal, or return True.

Using an SDK

If you use one of our official SDKs, you won't have to worry about any of the above — fetch your access token from the FastPDF profile under API settings, and the client library will take care of the rest.
