4. Backend and Steps
The backend for finetuning a Flux model involves several important steps:
After user payment is done, make an API call to Replicate or Fal AI to start the flux finetuning process
Add your WebHook URL in that api call so once the finetuning process is done you’ll be notified
Using the new model id we’ve received from the WebHook, we can now start generating images using the styles user has chosen.
