I’m trying to get/generate an API key to integrate with Mailerlite, through Zapier. Instructions at Zapier say to go to Settings>webhooks and API, but this doesn’t exist under settings. How can I go about getting my API? Thanks.
To expose your site you can use Wix Fetch or Wix HTTP Functions. as for working with Zapier, that is not a Wix company and you would therefore need to contact Zapier own support teams
