Instagram Publishing\n\n**Purpose:** This block takes the final image URL and caption, prepares them for the Instagram Graph API, uploads the media to create a container, waits for Instagram to process it, and finally publishes the container as a post to the connected Instagram account.\n\n**Input (from Nodes '3c. Generate Post Caption (Gemini)' & '4. Generate Image using Prompt 1 (Replicate Flux)'):**\n*   `ImageURL` (string: URL of the generated image from Replicate)\n*   `Caption` (string: Generated post text with hashtags from Gemini)\n\n**Process:**\n1.  **Format Data (`5. Prepare Data...`):** Organizes the ImageURL and Caption into the required structure.\n2.  **Create Media Container (`6a. Create...`):** Sends the `image_url` and `caption` to the Instagram Graph API (`media` edge) to initiate the upload. Receives a container `id`.\n3.  **Wait for Processing (`6b. Wait...`):** Pauses the workflow to allow Instagram's servers time to process the uploaded media. *Note: Wait time might need adjustment depending on media size and API responsiveness.*\n4.  **Publish Media (`6c. Publish...`):** Sends the container `id` (as `creation_id`) to the Instagram Graph API (`media_publish` edge) to make the post live.\n\n**Output:** The content is published as a new post on the target Instagram profile. The final node (`6c. Publish Post...`) returns the `id` of the successfully published media object on Instagram."}, "typeVersion": 1}, {"id": "d7082400-def2-40eb-9dbc-3e15d24c8f8f", "name": "Sticky Note5", "type": "n8n-nodes-base.stickyNote", "position": [4640, -480], "parameters": {"color": 6, "width": 380, "height": 300, "content": "# 05.
