Hey @Théo
Glad to hear you’re interested in embedding the Zapier experience for users of your app
This is only available to apps that are Published in the Zapier App Directory at this time, which have access to: https://platform.zapier.com/embed/full-zapier-experience
To submit your app for Publishing it would need to meet these guidelines: https://platform.zapier.com/partners/integration-review-guidelines
Published apps can also create Zap Templates, to guide your users through common workflows and simplify their setup: https://platform.zapier.com/partners/zap-templates
If that’s not something you choose to pursue, there is a zap.new shortcut, which if you type it into your browser, opens a new Zap in your Zapier account if you are logged in; or the Zapier login screen if you are not - not quite what you are looking for as it won’t create a Zap with your particular app, but I thought I’d mention it as one way to direct users from within your app to creating a new Zap!
