Attachments in Gmail

I am unable to send attachments in Courier using the Gmail integration.

Above is the link to some documentation I’ve found. My responses contain a data field, but i’m confused on the type of data this accepts. Is it Base64? I have a Supabase storage bucket with images, and additionally I use blob images inside my application.

I’ve tried sending requests with Base64 inputs, along with blobs and even links to the images. None of them work. Any idea what I should do?

Have you tried using a different provider? It should work with Mailgun, Sendgrid, SES, Postmark.
