To easily test and integrate with the SignRequest API you can activate a Sandbox team account and generate an API token. While using this specific API token all the documents sent are for free, but will contain a watermark.
Once you're ready to go into production you can either create a new team or switch the Sandbox team account into a production environment by using the 'Convert to production team' button on the team settings page. The watermark will then be removed. To switch to a production environment, you will need to subscribe to the 'Business' plan from our plans page. This can be purchased with a credit card or SEPA mandate. Please submit a ticket if you need any help with that.
Click on the "Convert to production team" button to convert to a real account where the watermark will be removed.
Activate a Sandbox team account
Log into your personal account and make sure you're not active in a team account. Otherwise you'll not be able to create a Sandbox team account. To switch between your personal and team account(s) have a look here.
Use this specific link to activate a Sandbox team account: Create Sandbox team

Generate the API token
