Real-Time API – "Input transcription failed" with 403 Forbidden

Hello,

I’m currently working with the OpenAI Real-Time API and I’m encountering the following error when attempting to transcribe the user’s message:

“Input transcription failed for item ‘item_C3M2hKgcuggeHfIf3Raas’. 403 Forbidden”

Some relevant details about my case:

  • I’m located in a country where access to the API is allowed.

  • I haven’t reached the rate limit for my API key.

  • The same code was working fine before with this prototype, so I don’t think it’s a coding issue.

Has anyone else experienced this issue recently or knows possible causes for this error? Any guidance would be appreciated.

Thank you in advance!
