Hi Luca 👋 You can't reference existing slides through the API unfortunately. It only generates new content from scratch, so there's no way to attach that perfectly set up thank you slide you've already got.
Preserve mode will keep your text exactly as you write it though, so you could include the contact info structured how you want. Separate items with \n (newline) in the inputText, and use \n---\n to create the slide break before your thank you section.
The images and QR codes are the tricky part. Can't pass those in via API, so you'd need to add them manually in the app after generation. You could also use imageOptions.source: "placeholder" to create empty image slots that you fill in afterward.
I know it's not the seamless approach you're hoping for. Image upload at generation time is a really popular request and the team's actively exploring it, just not available in the current beta yet.
