We are planning to use CRM Hubspot (https://share.hsforms.com/xxxxxxxxxxxx) to post leads for our client.
Could you please suggest the supported TLS for this API( TLS 1.0,TLS 1.1 or TLS 1.2)?
The HubSpot API supports TLS 1.0 and up. That said, I'm not familiar with that particular endpoint. Are you sure that's representative of the API you'll be using?
