Transport Layer Security (TLS)



Hi Team,

We are planning to use CRM Hubspot ( 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)?

Hi @Brijesh,

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?
