We have implemented new cybersecurity measures in the Rastro API, enhancing the protection of tracking information. Now, when checking the status of their shipments, users will have access to more secure and accurate data.
These changes are aimed at preventing third parties from accessing information about items shipped by contracted clients and to reduce the misuse of tracking data by unauthorized websites and applications.
Tracking queries are now restricted to items associated with the sender's contract, applying exclusively to the Rastro API. Clients using third-party platforms must use their Correios credentials to track their shipments.
With these measures, Correios reinforces our commitment to the security and reliability of our clients' data.

New Feature: Third-Party Access Delegation!

We’ve developed a new feature in CWS that allows the management of third-party access delegation for Correios' APIs and Systems. Now, contracted clients can grant a third party permission to operate on Correios' platforms, enabling them to query or use APIs and systems on their behalf while using their own access key. Access delegation can be done directly in CWS by contracted clients, following the respective permissions and restrictions defined.

This new feature ensures greater flexibility and security in access management! Click here to "create a new access key."
