Workflow Steps


1. Manual Trigger: The workflow begins when the user clicks the ‘Test workflow’ button.
2. Create Image Call: Sends a POST request to OpenAI's /v1/images/generations endpoint with a specified prompt, generating an initial image.
3. Convert JSON Binary to File: Converts the base64-encoded image returned from OpenAI into a binary PNG file format.
4. Edit Image: Sends the binary image to OpenAI's /v1/images/edits endpoint for further editing based on a new prompt.
5. Final Conversion: Converts the edited image, again in base64 format, into a downloadable PNG file for user access.
