The upload wp post tool allows you to set featured images in your posts
It requires a couple of things:
- Image in data64 format or src url inside the post
- Posting using JSON API only
- Enable feature in post uploader tool
Assuming your post has images inside.
You must use JSON API, you must add a blog with user name and a specifically created WP Application Password.
XML RPC posting will not work with featured images.
How to set featured images
Create new WP upload task
Check ‘use featured’
As long as the post has an image you will see a green checkmark in the image column
If there are problems you can hover for hints
eg: Not enabling featured images
eg: No images in post
Set JSON API posting
If you upgraded from an old version of SCM you can disable XML RPC first posting
Settings > task > xml rpc first = 0
