How to deal with WordPress and Pocket API to automate content curation on my hosted wordpress blog? [closed]

A quick look at the Pocket API, I think you might have to revise the objective.

When I mark a Pocket item as “favorite”, publish a new WordPress post with…

The way the API works is that you would get a list of articles from your wordpress plugin. https://getpocket.com/v3/get

Passing a few parameters like sort, favorite, and since

POST /v3/get HTTP/1.1
Host: getpocket.com
Content-Type: application/json

{"consumer_key":"1234-abcd1234abcd1234abcd1234",
"access_token":"5678defg-5678-defg-5678-defg56",
"sort":"newest",
"favorite":"1",
"since":"_timestamp_",
"detailType":"complete"}

You would want to store a timestamp each time your plugin queries the API, to avoid duplicates.

The detailType:complete will give you the title, tags, categories, images, etc. which you would plug into a custom content-type.

Your plugin could then post a draft of each item, which you could select to publish according to your hearts desire.

The quick and easy will depend on your skill level.
