On March 2, 2020, Acoustic Campaign removed support for TLS 1.0 and 1.1. Ensure that all mechanisms you use to connect to Acoustic Campaign support at least TLS 1.2.
Impact to Acoustic Campaign
The Transfer Layer Security (TLS) protocol is used to establish secure connections and encrypt communications across a network, ensuring that all transmitted data remains private. All client connections to Acoustic Campaign require TLS. This includes:
- Mobile app messages. For details on mobile app migration, refer to TLS 1.2 Migration for mobile push clients.
- Calling any of our APIs via any means
- Accessing the Acoustic Campaign via a browser on any device
- Transferring files to and from Acoustic Campaign using an SFTP tool or library
Users need to upgrade
To ensure that you don't encounter any problems with your connections to Acoustic Campaign, you need to:
- Update your API client and client libraries to use TLS 1.2.
- Ensure your workstations and mobile devices (if used) are updated with the most current version of the operating system and supported browsers, which will include support for strong protocols and ciphers.
Note: This change does not impact outbound email (SMTP), SMS, or mobile message traffic. The strict TLS 1.2 enforcement does not apply to inbound recipient activity (tracking links, landing pages, and web forms) as we continue to provide backward compatibility to ensure a good recipient experience.
