LinkedIn to SHA256

The LinkedIn to SHA256 API retrieves a SHA256 and MD5 hashed email for a LinkedIn profile, covering both a business and a personal address.

It returns a single business hash and a single personal hash in each format, giving you broad coverage for audience matching across ad platforms. Use this when you need a full match key set for a LinkedIn-identified contact, for example to maximise match rates when uploading customer lists to Meta, Google, or LinkedIn Ads.

Use this endpoint to:

• Maximise match rates on ad platform customer lists
• Build a complete hashed identity set for one contact
• Bridge LinkedIn-sourced contacts into advertising audiences

Need multiple SHA256s? This API returns only ONE SHA256. If you are running ads and want MULTIPLE SHA256's, and are willing to spend at least $10k/yr, please <a href="https://moltsets.com/data-sales/?product=linkedin-to-sha256" target="_blank" rel="noopener">click here</a> and talk to our data team.

Plan Availability: This endpoint is not available on the $397 / month and $997 / month plans. Calls from those plans return 403 with plan_restricted. It is a plan condition, so retrying or topping up tokens does not clear it.

Response fields: Each hash field holds one string, not an array. A field with no data is left out of results, so a profile with only a business email returns just the business_ fields. Check for a field before reading it.

Outcomes: A lookup that finds nothing is not an error. It returns HTTP 200 with status: "not_found", empty or null results, and the usual metadata — and costs no tokens, though it still counts as one request against your Fair Use requests limit. Read status, not the HTTP code, to tell a hit from a miss. The API's only 404 is an unknown or retired tool name.
