Breaking Change

Fix validBefore/validAfter semantics in TRLink policy rules

Products: Transactions

Scope: API + SDKs

• What's new
  Corrects the documentation for validBefore and validAfter fields to accurately describe their behavior as relative durations (seconds since wait/screening step started) rather than absolute Unix timestamps.

• Impact
  Customers should update their implementations to use relative durations in seconds instead of Unix timestamps for these fields.

Affected endpoints:

1. Get a specific transaction by external transaction ID
2. Get a specific transaction by Fireblocks transaction ID
3. Get transaction history

Fix validBefore/validAfter semantics in TRLink policy rules

Products: Compliance

Scope: API + SDKs

• What's new
  Corrects the documentation for validBefore and validAfter fields to accurately describe their behavior as relative durations (seconds since wait/screening step started) rather than absolute Unix timestamps.

1. Provides all the compliance details for the given screened transaction.

Remove type field from security finding responses

Products: Security Posture Management

Scope: API + SDKs

• What's new
  Removes the type field from security finding schemas and updates example data to reflect a different finding scenario.

• Impact
  Clients should no longer expect the type field in security finding responses and must update any code that depends on this field.

Affected endpoints:

1. Get a FSPM security finding by ID
2. Update a FSPM security finding by ID
3. Get FSPM security findings

Added

Add contacts list endpoint

Products: Contacts

Scope: API + SDKs

• What's new
  Adds a paginated endpoint to list workspace address book contacts with filtering by name, type, tags, access control, container, and archive status.

2. Estimate transaction fee
3. Add Collateral
4. Remove Collateral

Add AMOUNT_ABOVE_MAXIMUM failure reason

Products: Trading (Beta)

Scope: API + SDKs

• What's new
  Adds a new enum value to indicate when a trading operation fails because the requested amount exceeds the maximum allowed limit.
