Automating upload of an Account Image

Automating upload of an Account Image

Is it possible to upload an image to the Account_Image field in CRM?

I tried this to copy an existing image to another record to another but it did not work...
  1. response = zoho.crm.getRecordById("Accounts", 000000000000000000);
  2. imageFile = response.get("Record_Image");
  3. update = {"Record_Image": imageFile};
  4. response = zoho.crm.updateRecord("Accounts", 1111111111111111, update);
This did not work either (although admittedly the documentation for the .getFileContent() did say it returns junk from image files)...
  3. fileVariable = invokeUrl
  4. [
  5. url: "https://... image.png"
  6. type: GET
  7. ];
  8. imageFile = fileVariable.getFileContent();
  9. update = {"Record_Image": imageFile};
  10. response = zoho.crm.updateRecord("Accounts", 11111111111111, update);
Very grateful for help
