We currently support attaching the following file types:
We support this via Data URLs and we would recommend using a library to simplify this process (although it's entirely possible to DIY).
from datauri import DataURI str(DataURI.from_file('test.pdf')) # => data:application/pdf;base64,JVBERi0xLjMNJeLjz9 (truncated)
const Datauri = require('datauri/sync'); Datauri('test.pdf').content; // => data:application/pdf;base64,JVBERi0xLjMNJ (truncated)
We do not have an explicit limit set on the attachment size, but we do have a 25MB (26214400 bytes) limit on the request body size.
Assuming your request body is 1MB without the attachment, that leaves 24MB before hitting our limit.
In the worst-case scenario, base64 encoding increases the original file size by 4/3.
So with a 1MB body, you could include up to 18MB (18 * 4/3 == 24MB) of attachments in the request.
