I'm getting an error: "sslv3 alert handshake failure"

We don't support SSLv3 due to a security vulnerability: .

You can force SSLv2 by using the --sslv2 flag with curl on most systems.

You can also just POST to http://textbelt.com/text, as opposed to https://. This will solve the problem, but traffic will not be encrypted (you might be ok with this for hobby projects because to begin with).

Can I use Textbelt via Tor?

No, because of too much spam/abuse coming through Tor.

Can I use Textbelt with Postman?

Yes. Here's a screenshot of a Postman configuration that works:

Why isn't my VOIP number receiving SMS?
