Obtain LinkedIn Talent Solutions partner credentials through the formal partner program; Recruiter System Connect (RSC) unifies candidate data between LinkedIn Recruiter and ATS and requires partner-level API access.
Use the LinkedIn Job Posting API (using API version 202504 or current) to create or sync job postings from your ATS to LinkedIn, passing the job title, description, location, and employer URN.
Configure the RSC connection so that recruiter actions in LinkedIn Recruiter (notes, InMail, status updates) are reflected in the ATS candidate record and vice versa.
Implement a webhook or polling mechanism to receive InMail responses and application updates from LinkedIn and merge them into the corresponding ATS candidate timeline.
Handle LinkedIn URN-based identifiers for members, organizations, and job postings consistently throughout your data model — URNs are stable but distinct from ATS-internal IDs.
Regularly validate that the job posting sync is current by comparing job statuses in LinkedIn with the ATS; closed or filled roles in the ATS should be closed on LinkedIn promptly to prevent applications on inactive postings.
Known gotchas
LinkedIn Talent API versions are dated (e.g., 202504) and must be specified in API requests; using an outdated version string may return deprecated data structures or errors after LinkedIn retires that version.
Data returned via RSC is subject to LinkedIn member privacy settings — some profile fields are restricted and cannot be retrieved even for candidates who applied; design data ingestion to handle missing optional fields gracefully.
Job posting distribution via the API counts against LinkedIn's content policy and partner terms; bulk-posting low-quality or duplicate postings can result in partner account suspension.
