Hi Dan 👋 this is not currently possible with the beta version of the API but will be very soon (though I cannot share specifics).

exciting - ok, any workarounds with templates or anything?

or enforcing it on a title slide perhaps?

If you create a custom theme in your Gamma workspace that includes your logo, you can use that theme when generating via the API. The theme will apply your branding, including the logo, to the generated cards. Here's the workflow:
1.
Create a custom theme in Gamma with your logo included
2.
Find the theme name
3.
Use it in your generation request with the themeName parameter
The theme should handle the logo placement for you automatically.

Max J. I think we removed the automatic logo now that we have card headers and footers

Thanks for the jumping in there Nikolas P.! To clarify Dan P. uploading a logo to a theme only places it on the bottom left corner of each slide, but there's not a way to programmatically assign values to the header and footer via the API yet.
