Hi everyone, we are implelenting a blog stream in a client’s website therefore we are using API cURL call `https://api.hubapi.com/content/api/v2/blog-posts?hapikey=demo&updated__gt=1430452800000&content_group_id=351076` we are facing an issue: blog post have been tagged with several tags, such as News, Events or other marketing tags. what we are trying to make out is if there’s a way to list ONLY posts tagged with specific single keyword such as NEWS. thank you! ---

@matteo - Unfortuanately, you cannot query the API with a blog topic name. However, you can use the[topics api endpoint](https://developers.hubspot.com/docs/methods/blog/v3/list-blog-topics) to get the topics that you need to query, which will get the relative ID to that topic. Then, you can pass a parameter of **topic\_id=** to your blog post listing API call. example: [https://api.hubapi.com/content/api/v2/blog-posts?hapikey=demo&topic\_id=53100784](https://api.hubapi.com/content/api/v2/blog-posts?hapikey=demo&topic_id=53100784) * * * If this answer helped, please, mark as solved 😄 * * * [tim@belch.io](mailto:tim@belch.io) | [forms.belch.io](https://forms.belch.io) | Design your own Beautiful HubSpot Forms; No coding necessary.

@tjoyce is it possible to pass multiple topic id values to the same topic\_id query parameter? Something like &topic\_id=xxxxxxxx&xxxxxxxx OR &topic\_id=xxxxxxxx&topic\_id=xxxxxxxx ? ---

Hi @MFall13 - I have not tried to search multiple topics before but perhaps the double underscore query might be something you can explore… Something like `&topic_ids__in=10945,28906` However, I suspect something like this might return only posts that appear in both topics… might need some guess work done around this ```auto Optional query string filters & options Some parameters support "range" filters via double-underscored param suffixes, like '__gt'. If a parameter supports a filter type of 'gt', that means you can append a double-underscore and 'gt' to the parameter name to find all items greater than a specified value. For example, the following query will find all items with the 'updated' time greater than 1364424600000: https://api.hubapi.com/blogs/v3/topics?hapikey=demo&created__gt=1364424600000 ``` ---

@tjoyce thanks for the suggestion. I feel like I’ve tried every value filter combo out there. `&topic_ids__in=30111149151,32404273845" (and &topic_id__in too)` returns `Invalid query Filtering by \"topic_id(s) in\" is not allowed` … another try with the following exact params: `&topic_id=30111149151&topic_id=32404273845` responds with a valid request, but only pulls in blogs with the first topic id …and another try with the suffix ‘\_\_contains’ to no avail. Any other suggestions? Much appreciated!
