We use the oAuth 2.0 standard for authenticating apps with Jumplead. Details can be found in our API documentation.
How you do this will be dependant on which programming language you're using. We recommend using an existing library to connect as it'll save you time. A list of client libraries can be found on the OAuth website and a quick search online will find even more.
At this time, our API includes access to Automations, Contacts, Companies and Stages. We will be expanding this in future to include more areas of Jumplead.
