Hi @Juan Carlos Barreno Bravo,

I will recommend you to use base64 encode URL to download the record. You can refer to following steps

1. Convert the base64 encoded result to unpadded base64url format by removing = characters from the end of the value, replacing / with _ and + with -.
2. Append u! to be beginning of the string.
3. After encoding url with base64 and following above steps, will get a string in below format

4. Using the example Access the shared item directly, can get the file content
   GET /shares/{base64encoded-callRecordingUrl}/driveItem/content
