TLS
Transport Layer Security (TLS), or its earlier version Secure Sockets Layer (SSL), are the most popular and important security protocols on the internet. Nearly all websites protected by cryptographic means rely on protocols that are part of the SSL/TLS suite.

In business automation
TLS encrypts traffic between a client and a server. In automation, it is the foundation for every API call, webhook, and dashboard: without valid TLS, secrets and data travel in the clear or are exposed to an impersonator.
Examples
These examples illustrate a possible workflow. Adapt the connections and rules to your own systems.
Store webhook with a valid certificate
The store sends an order event to the workflow's HTTPS address. The server presents a signed certificate. If someone tries to intercept the traffic without an appropriate certificate, the connection fails instead of transferring order details.
Relevant tools
- Vercel
- A site deployment receives a TLS certificate for its domain; outgoing API connections still require checking that the destination uses valid HTTPS.
What to check
- An HTTPS address with an expired certificate or disabled verification during testing may remain that way in production.
