  3. Sets Topic for AI Research: It prepares the topic data for the subsequent AI research step.
  4. Researches Topic with Perplexity AI: It makes an HTTP request to Perplexity AI to gather information and insights about the trending topic.
  5. Aggregates Research Results: It combines the research results from Perplexity AI into a single output.
  6. Generates Blog Post with OpenAI (GPT): It uses the aggregated research to prompt OpenAI's GPT model to generate a comprehensive blog post.
  7. Publishes to WordPress: Finally, it takes the generated blog post content and publishes it as a new post on a configured WordPress site.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
