Enabling SSO for an organization may affect your REST API integrations, particularly the ones using Content Management APIs. It is therefore recommended that you read this section carefully.
Content Delivery API
For an SSO-enabled organization, Content Delivery APIs work as expected. The Content Delivery API requests are GET calls and they use the stack’s delivery tokens to fetch content. No changes are required.
Content Management API
Any user who accesses the SSO-enabled organization through IdP login cannot make Content Management API requests since it requires a user authtoken. Below we will explain a couple of options on how to utilize the Content Management API for specific users when SSO is enabled.
Since the owner of an organization can access an SSO-enabled organization through Contentstack credentials as well, he/she has a user authtoken. The owner can use this authtoken (received in the response of the “Login” request) to make Content Management API requests.
Similarly, if you have disabled Strict Mode for an SSO-enabled organization and granted a few users the permission to access the organization through Contentstack credentials (by enabling the Allow Access Without SSO option in the Organization Users page), then these users can use the authtoken to make Content Management API requests.
Additional Resource: For SSO-enabled organizations, instead of logging in with credentials and generating an authtoken, users can directly use the Content Management APIs to read, create, update, or delete content using the management token.
