The first step is to generate an access token, which will enable access to the Rev AI APIs. Follow these steps: The new access token will be generated and displayed on the screen. Save your access tokens somewhere safe; you will only be able to see them once. You are allowed a maximum of 2 access tokens at a time. Submit an audio file for transcription to Rev AI using the command below. Replace the REVAI_ACCESS_TOKEN placeholder with the access token obtained in Step 1, and replace the sample file URL shown below with the URL to your own audio file if required. You'll receive a response like this: You now need to wait for the job to complete. Wait for approximately 1 minute and then check the status of your job by querying the API as shown below: Polling the API periodically for job status is NOT recommended in a production server. Rather, use webhooks to asynchronously receive notifications once the transcription job completes.
