Dear sharavanak20,

Please share with an example of your request and we will be glad to assist you with it.

The audio tag can play from URL or base64 audio content.
Please be sure that the requests parameter ‘b64’ set to ‘true’.
In this case the API returns an audio content in the base64 string format which playable by the audio tag.

Please find below the link to the API documentation which may be helpful:
