Receiving attachments

Bytes on webhook and on message show.

Each attachment hash has filename, content_type, and size. Bytes are not on the list endpoint.

Where the bytes are

  • JSON receiving webhook. Each attachment includes content_base64.
  • GET /api/v1/inboxes/:id/inbound_messages/:id. Same content_base64 field, plus raw for the MIME.
  • sendgrid_parse webhook. Parts are attachment1, attachment2, and so on. attachment-info holds filename and type. email is the raw MIME.

Index rows stop at metadata. Use show or the webhook when you need the file.
