AddCompanies

Add up to 100 companies to your workspace’s blacklist in one call. Leads working at a blacklisted company are excluded from your campaigns.

Each entry takes one or both of the following, and at least one is required:

• url (optional): a LinkedIn company URL, linkedin.com/company/..., with or without https:// and www.. The URL is reduced to the company slug, so every spelling of the same company - scheme, host, query string, fragment, trailing slash, an /about/ suffix - collapses onto one entry. School URLs and bare domains such as acme.com are rejected.

• name (optional): a name-only entry, excluding by exact, case-insensitive company-name comparison. Returned as BroadMatch.

The call returns 200 even when some entries do not land, following the same partial-success model as ‘AddLeads’:

• added: how many entries were newly created.

• entries: one reference per input that produced a stored entry, correlated by inputIndex (its position in the list you submitted). id is what you pass to ‘RemoveCompanies’, and created is false when the company was already blacklisted.

• duplicates: identifiers that were already blacklisted, or repeated within this batch.

• validationErrors: one message per entry that was skipped, for example an invalid URL or an entry with no identifier at all.
