      Improved
      Aiven API

    Project-based user and invitation management API endpoints are deprecated

    Project-level invitations and membership management have been deprecated. The organization APIs are now used to invite users to an organization, and the permissions endpoint lets you give users access to projects. As part of this change, the following project-based API endpoints are deprecated and replaced with organization-based equivalents:

    • POST /v1/project/{project}/invite: Use POST /v1/organization/{organization_id}/invitation instead
    • POST /v1/project/{project}/invite/{invite_verification_code}: Use POST /v1/organization/{organization_id}/invitation/weblink/{invite_verification_code} instead
    • GET /v1/project/{project}/users: Use GET /v1/organization/{organization_id}/permissions/project/{project_id} instead
    • PUT /v1/project/{project}/user/{user_email}: Use PATCH /v1/organization/{organization_id}/permissions/project/{project_id} instead
    • DELETE /v1/project/{project}/user/{user_email}: Use PATCH /v1/organization/{organization_id}/permissions/project/{project_id} instead

    For more information, see the Aiven API documentation.

    Announcing Aiven Apps in limited availability

    You can now deploy and run containerized applications directly within your existing Aiven project infrastructure.
