Unipile offers two methods tu run a search :

With filters : you provide any combination of parameters directly in the method body. E.g. : keywords, date_posted, author, etc.
From URL : you provide the URL of a LinkedIn native search so the filters can be automatically infered.

📘
Note about Search Parameters
Many of the search filters on LinkedIn work with IDs that reference parameters, rather than the parameters themselves.
For example, in the posted_by[member] filter, you cannot directly insert John Doe, but instead you should use the corresponding member ID.
Use the List Classic Search Parameters endpoint to help you find the IDs of the parameters you need.

Search with filters

To get a list of posts search results with filters, use the Perform Posts Search endpoint with a parameters body.

📘
Note about pagination
Pagination on this endpoint uses exclusively the offset parameter.

const { data } = await linkedInApi.performClassicPostsSearch({
  path: {
    account_id: "acc_123456789",
  },
  body: {
    keywords: 'Productivity',
    posted_by: {
      member: ['ACoA1B2C3D4E5F6g7Hi8J9K1L2m3NOpqRSTUvWxYZ']
    }
  },
});

posts = linked_in_api.perform_classic_posts_search(
    "acc_123456789",
    perform_classic_posts_search_request={
        "keywords": "Productivity",
        "posted_by": {
            "member": ["ACoA1B2C3D4E5F6g7Hi8J9K1L2m3NOpqRSTUvWxYZ"]
        },
    },
)

curl --request POST \
     --url https://api.unipile.com/v2/account_id/linkedin/search/posts \
     --header 'accept: application/json'  
     --data '
{
   "keywords": "Productivity",
   "posted_by": {
     member: ["ACoA1B2C3D4E5F6g7Hi8J9K1L2m3NOpqRSTUvWxYZ"]
   }
}'

Search from URL

For a URL to be considered valid in the context of a posts search, it must match the following pattern : https://www.linkedin.com/search/results/content.

To get a list of posts search results out of a URL, use Perform Classic Search from URL.

const { data } = await linkedInApi.performClassicSearchFromUrl({
  path: {
    account_id: "acc_123456789",
  },
  body: {
    url: "https://www.linkedin.com/search/results/content?[...]",
  },
});

posts = linked_in_api.perform_classic_search_from_url(
    "acc_123456789",
    {"url": "https://www.linkedin.com/search/results/content?[...]"},
)

curl --request POST \
     --url https://api.unipile.com/v2/account_id/linkedin/search \
     --header 'accept: application/json'  
     --data '
{
   "url": "https://www.linkedin.com/search/results/content?[...]"
}'
