Check certificate pinning, custom trust-store assumptions and official TLS-test evidence before Twilio rotates REST API endpoint certificates on 9 September 2026.
Direct answer
Use this browser-local preflight to surface manual certificate pinning, untested proxy paths and missing tls-test evidence before Twilio rotates the REST API leaf certificate. Never enter private keys, account credentials or certificate secrets here.

0/5 answered
Every important Twilio REST caller and network path is inventoried
Include apps, jobs, proxies, service meshes and runtimes that terminate or inspect TLS.
Code and configuration have been checked for leaf-certificate pinning or manual serial/fingerprint trust
The risk is concentrated in custom pinning or manual certificate handling rather than normal platform trust.
tls-test.twilio.com succeeds from each important execution environment
Run the official compatibility test from the same kinds of paths that make production REST calls.
Any failed path has been remediated without introducing a new brittle leaf-certificate dependency
Prefer supported trust-chain handling over pinning the current end-user certificate.
A dated owner and pass/fail cutover record exists for 9 September 2026
Keep enough evidence to know which runtimes were actually tested.

Run Twilio REST TLS Rotation Preflight Gate before paying. The three paid tiers buy bounded written proof, diagnosis or an action pack; they do not silently imply a subscription, deployment, certification or legal/compliance decision.

Compatibility-readiness only. This app does not inspect your certificates, contact Twilio with credentials, modify trust stores or prove every production route is identical to the tested path.

The buyer answer is visible HTML. Structured metadata supports discovery, but the useful content and working free path are not hidden in schema.
Check certificate pinning, custom trust-store assumptions and official TLS-test evidence before Twilio rotates REST API endpoint certificates on 9 September 2026.
Yes. The bounded browser-local platform migration preflight proof stays available without signup. Use the free path first and only pay when the workflow needs evidence, implementation help, larger scope or human review.
Paid work is deliberately separate from the free proof: $5 buys a bounded first proof, $50 a focused diagnostic and $99 an action pack. Larger implementation is scoped only when evidence supports it.
