Automation & No-Code, Business & Payments, Email & Newsletters

This task documents how to create a grace-period reminder for expiring subscriptions. It focuses on practical steps to capture the question and categories and turn them into structured content for a WordPress 'tasks' post.

You will map the input data into a clear post payload, including a suitable title, slug, categories, and metadata that helps readers implement the reminder process.

Who is this for?

- Content editors and marketers
- Product and subscription managers
- Support teams documenting workflows
- Developers implementing content templates

Before you start

- Access to WordPress with the 'tasks' CPT
- Basic JSON parsing and string handling
- Clear input with question_raw and categories

General Process (How it works)

  1. Parse input and extract data Read the injected text and parse the inner JSON to obtain question_raw and categories.
  2. Validate parsed data Ensure question_raw is non-empty and categories contain at least one value.
  3. Derive post core fields Create title and slug from question_raw. Prepare post_type and status.
  4. Map categories and metadata Split categories into an array and assemble core meta fields.
  5. Assemble SEO and structure Populate SEO fields and build JSON meta payloads.
  6. Generate final post payload Combine all fields into a single post payload ready for n8n output.
  7. Return payload and ensure uniqueness Ensure slug uniqueness within this output and return as final JSON.

Common beginner mistakes

❌ Assuming input is always clean
❌ Skipping slug uniqueness checks
❌ Overloading meta with too much text
❌ Ignoring required fields
