Using the client library you can set the base64 encoded email to the raw property of a Message then use that Message as the message property of the Draft.

More generally: The Draft Message consists of an id and a Message Resource https://developers.google.com/gmail/api/v1/reference/users/drafts

{
  "id": string,
  "message": users.messages Resource
}

The Message Resource should have its "raw" field set to a base64 encoded RCF 2822 formatted string.

Eg:

from: me@email.com
to: you@email.com
subject: test email

email body

As a base64 encoded string is:

ZnJvbTogbWVAZW1haWwuY29tDQp0bzogeW91QGVtYWlsLmNvbQ0Kc3ViamVjdDogdGVzdCBlbWFpbA0KDQplbWFpbCBib2R5

So the request body of a draft.create should look something like:

{
  "message": {
    "raw": "ZnJvbTogbWVAZW1haWwuY29tDQp0bzogeW91QGVtYWlsLmNvbQ0Kc3ViamVjdDogdGVzdCBlbWFpbA0KDQplbWFpbCBib2R5"
  }
}
