Stay in control of your data

Choose the authentication method that best suits your needs

At ProWorkflow we know that different companies have different needs when it comes to access to their data. That’s why we offer two different authentication methods for accessing our Nexus API and connecting to your data.

  • Use an API key to connect to your account with no restrictions; useful for creating integrations and automations.
  • Register an OAuth app to create and manage JWT Bearer Tokens
  • JWTs allow you to grant access to the API that respects the access and visibility permissions you set against a user in ProWorkflow
