Attenuate token
Add restrictions to an existing token without needing the private key.
Attenuation is a Biscuit cryptographic feature that allows anyone holding a token to add restriction blocks. The resulting token can only do a subset of what the original token could do—restrictions cannot be removed.
Security Model
This endpoint requires the token:read capability.
-
Cryptographic guarantee: Attenuation can only reduce permissions, never expand them. The Biscuit format ensures restriction blocks are append-only and cannot be removed without invalidating the signature.
-
Self-service by design: Users can only attenuate tokens they already possess. If you have a token, you can create a weaker version of it—this is analogous to being able to share read-only access to something you own.
-
No privilege escalation: The attenuated token inherits all existing restrictions from the source token, plus any new ones added. A read-only token cannot be attenuated into a read-write token.
Use Cases
- Create a read-only version of your token for delegation
- Restrict a token to specific resources or actions
- Generate time-limited tokens for external services
- Scope a broad token down to a single organization or project
Timezone
All timestamps use UTC in ISO 8601 / RFC 3339 format.

}Authorizations
Biscuit-based bearer token. Obtain tokens from the Adaptyv Portal or via the /tokens endpoint. Tokens encode organization membership and role-based capabilities; the API verifies the token's cryptographic signature and authorization claims before processing requests. Use /tokens/attenuate to create restricted tokens for delegation.
Body
application/json
Request to attenuate (restrict) an existing token.
Attenuation is a Biscuit cryptographic feature that adds restriction blocks without needing the private signing key. Any authenticated user can attenuate their tokens to create limited-scope versions for delegation.
Restrictions to apply to the token.

Human-readable label for this attenuated token.
Names are not unique — they are purely for display purposes.
Existing token string (format: abs0_{slug}{biscuit_base64}) to attenuate.
If attenuating an already-attenuated token (chained attenuation),
provide the id of the parent attenuated token record. Omit when
attenuating a root token directly.
