Hi, @PLucas2👋 Great questions. The quick answer is if it is HubSpot created or listed on the HubSpot Marketplace, it is not affected. If it is a 3rd party tool (#3) it is up to the creator to update their tool before the sunset in November.
HubSpot All-In-One Marketing—Forms, Popups, Live Chat — Not affected
MWB HubSpot for WooCommerce — Not affected
WPOP Contact Form 7 to HubSpot — you will need to reach out to this integration creator and inquire when and if they are updating. Their support documentation still instructs folks to generate an API key. WPOP Contact Form 7 — Generate an API key
For #3, my goal is not to be elusive. I cannot answer about when they will get their product updated, only they can.
