Q: What is disclosedVendors?
A: It’s a TC String segment that lists the vendor IDs that were disclosed/shown to the user in the CMP interface.
Q: Do I need to update my website code?
A: Typically no. You should just ensure you’re running the latest Termly embed script and that IAB TCF is enabled for the EU region.
Q: Will old TC Strings break?
A: No, TC Strings created before the enforcement date remain valid per the spec; enforcement applies to newly created strings after Feb 28, 2026.
Q: How does Termly know which vendors to include?
A: When TCF is enabled, Termly uses your configured vendor list. Vendors can be auto-detected during scans and can also be managed manually in the Vendors page.
Q: Will this change my banner UI/behavior?
A: Enabling IAB TCF already enforces certain TCF-required behaviors and restricts some customization options for EU experiences. This update is primarily about TC String compliance.
