Sandbox API key


Availability: Enterprise plan, Business plan by request

We don't charge for making API calls with the Sandbox key. Developers can use the Sandbox key to evaluate our API and build a Proof of Concept.


  • API calls with the Sandbox key have a limit of 10 requests per minute, per endpoint.
  • Generated PDFs have watermarks and created documents have the "[DEV]" prefix by default.
  • During a free trial term, you can send documents only to emails within your domain.
