we have created a Hubspot form to allow our users to subscribe to our newsletter, and that form is linked to a Hubspot landing page. Double opt-in is enabled for that landing page, so when we navigate to that page directly in the browser and submit the form from there, everything works as expected, a new contact is created and a transactional email is sent so it can confirm the subscription.
However, when we try to collect the data in our own form and send it to the hubspot form via the Forms API it doesn’t work, because the contact is created but the email is not sent. We have tried to include the URL of the landing page in the hs_context param, but that doesn’t work either…
Any ideas on what the problem might be?
