Filter posts tags by WordPress api

To filter posts by tags using the WordPress REST API, you can use the tag query parameter in the API endpoint for retrieving posts. The API endpoint for retrieving posts is /wp-json/wp/v2/posts.

Here’s an example of how to retrieve posts with the tag “news”:

https://example.com/wp-json/wp/v2/posts?tags=news

This will return an array of posts that have the “news” tag. You can also use the per_page parameter to specify the number of posts to return, and the page parameter to specify which page of results to retrieve.

Here’s an example that returns 5 posts per page, with the second page of results:

https://example.com/wp-json/wp/v2/posts?tags=news&per_page=5&page=2

You can also filter posts by multiple tags by passing a comma-separated list of tag slugs to the tags parameter. For example:

https://example.com/wp-json/wp/v2/posts?tags=news,events,sports

This will return an array of posts that have either the “news”, “events”, or “sports” tag.
