There are a few options you have with integrating your lead capture with Táve and WordPress. The simplest and quickest way to get up and running it to use the Táve contact form and embed it using an iFrame. If your WordPress theme doesn't support iFrame, we suggest trying the Advanced iFrame plugin.
The other two options are Gravity Forms and Contact Form 7. Both of these contact form plugins have additional Táve integration plugins that you can install.
