If you want to use API's you'll need either an OAuth Client (for OAuth) or an Integration ID (for Basic Auth).
Important: Towards the beginning of 2027 we're planning to retire all Integration IDs. This means that Basic Auth will soon no longer be accepted for API access. Oracle strongly recommends the use of OAuth as it provides a higher level of security. See Implement OAuth.
If you're not already subscribed to receive updates, we encourage you to subscribe to API News for important information regarding Basic Auth retirement.
Basic Authentication (also known as Basic Auth) involves sending the credentials of a user account (username and password) with every API request. Org Admins can also assign permissions to allow users to create, view, update and deactivate integration IDs within your organization.
An Integration ID can only be used on the Aconex instance it was created on. You must create a separate Integration ID for each instance of Aconex you want to integrate with.
