Hello Snahasish, You are having troubles with which step? download a file stored in GCS or attaching the file through the SendGrid API? Are you using any library to interact with SendGrid (https://github.com/sendgrid/sendgrid-java)?
If you're using the SendGrid library have you tried attaching the InputStream as shown here? https://github.com/sendgrid/sendgrid-java#attachments I'm doing exactly the same but with another mail provider instead of SendGrid. I'm using jersey with *FormDataMultiPart* and *StreamDataBodyPart *classes to send the request with the attachment to the API (with no specific client library, just Jersey) FormDataMultiPart formData = new FormDataMultiPart(); formData.field("from", emailFrom); formData.field("subject", subject); formData.field("html", content); formData.field("to", email); StreamDataBodyPart bodyPart = new StreamDataBodyPart("inline", imageInputStream,filename,new MediaType("image","png")); formData.bodyPart(bodyPart); Client client = Client.create(); client.addFilter(new HTTPBasicAuthFilter("api", API_KEY)); WebResource webResource = client.resource(API_ENDPOINT + "/messages"); webResource.type(MediaType.MULTIPART_FORM_DATA_TYPE).post(ClientResponse.class, formData); Let me know if this is what you are looking for. Cheers.
