Authorization

To use pdf4me, you need to authenticate with basic authentication. You can get a free trial Api Key from our web portal. When using the Pdf4meApi directly you can set the basic authentication in the Header as following:

  • Authentication: Basic <Your Key>

Please login with your social account or create an account here. Once logged in you have access to your free credentials. Authorization happens through the Pdf4meClient. The credential hand-over is language dependent.

Check the Subscription tab after logging in. Select the ‘Default’ application or create an application using ‘Create Application’.

Copy the Primary/Scondary key and pass it to the authentication code (token).

Sample

  • curl
  • C#
  • Java
  • JavaScript
  • PHP
  • Python
  • Ruby
curl No Sample
