After you have created an account, you will find your important API tokens (secret keys) for your account in the Account menu to the right of the top menu bar.
Once selected, the Token Dialogue is shown. Here tokens can be viewed and copied:
Shop-Token: The shop token allows the loading of Templates and Snippets, uploading images, and saving / loading the current layout.
Service-Token: The secret service token has access to the production API and can render PDFs and PNGs. It is only viewable on accounts with administrative access.
Embed: Here you will find a convenient example embedding code for the current Template. See section “Embedding The Editor” for further details.
The service token should only be used on Server Side to process orders. With it, billable orders can be started. To protect your account never embed the service token into a website!
