After a manual trigger, it sets the creative prompt and logo/reference image, normalizes image URLs, and then splits into two parallel branches: one generates the branded visual through Kie AI Seedream 4.0 with async wait/resume handling, while the other uses an OpenAI chat model and a Social Media Manager chain to generate an Instagram-ready caption with emojis and hashtags. The workflow then merges the finished image and caption, uploads the image to Postiz, and schedules or publishes the post to Instagram.\n\n### Setup steps\n\nAdd and verify the required credentials for OpenAI, Kie AI, and Postiz before testing the workflow. Optionally update the `Set params` node to change the image prompt, confirm the `Wait` node\u2019s resume webhook is reachable for async image generation, and check that the Instagram/Postiz integration ID is correct. If you want automated scheduling instead of manual testing, replace the Manual Trigger with a schedule trigger. Run a manual execution first to validate the full flow from prompt generation to image creation, caption output, upload, and Instagram publishing.\n"
