In order to get started, you'll want to review the Concord API documentation here: http://docs.concordapi.apiary.io
We have a sandbox where your colleagues can start work on our API. Thus, your colleagues will be able to play with our API without the risk of deleting some documents in your real account.
One person should create an account in the Sandbox and invite colleagues (as needed) within Concord, here is the URL: https://uat.concordnow.com/negotiation/library/#/account-activation
For future UAT logins, here's the sandbox URL: https://uat.concordnow.com/
Once this is done, we will activate the API key on the sandbox. Then send an email to firstname.lastname@example.org and provide us with the emails of the people who created an account on the sandbox (please note: the email address you provide us MUST be a user already in your Concord account).
