How does the trial / development plan work?
150 credits per month are free. A credit is used for each call to the GroupDocs Cloud API and for further details about credits view the pricing page. You get access to all the features of GroupDocs Cloud. There are no limitations and no evaluation messages on documents.
This plan is intended to give you a good idea of the service's capabilities and let you do some early development. Once your development needs exceed the limits of this plan you should subscribe to a paid plan to continue development.
The free trial is automatically granted when you sign up with a new account and access the dashboard.
