How it works

One flow, from people to your product

Your people complete Thomas assessments; Thomas turns them into validated intelligence; you extract it wherever you need it.

1
Connect your people

Resolve or import your directory. We match each person by email or HRIS id.

POST /v1/individuals/resolve
2
Trigger an assessment

Invite a colleague to a Thomas assessment, or surface it inside your own flow.

POST /v1/assessments/assignments/bulk
3
Use the intelligence

Extract profile data and connection insights into your product, for one person or a whole team.

GET /v1/assessments/profile/{individualId}

Every call in this path is made by your API client, acting as itself. Your client can also act on behalf of a named person, for example to coach them or to share their result with their manager. Concepts explains the three callers.

    One integration, many outcomes

    A few of the things partners build today. The same people-data powers the whole employee lifecycle, from hiring to communication, development, role changes and offboarding.

    Assess candidates

    Assign assessments to candidates already in Thomas by their Thomas id, then read each behaviour profile or compare two people once they finish.

    Guide managers

    Surface how to work with and communicate with each report, directly inside Slack, Teams or your HRIS.

    Help people progress

    Recommend the next learning step from a person's profile, in your LMS.

    Run better reviews

    Enrich performance reviews with connection and behaviour insight, not just ratings.

    Not only for HR. Any product with people in it (a CRM, a collaboration or project tool, a community) can embed Thomas. People get assessed when you trigger an assessment; they complete it once, then the profile is available everywhere you build.
    Build from examples

    Bulk endpoints, validated up front and idempotent by email. A full directory is about 100 batched calls, not 10,000.

    Validate firstDry-run a batch of up to 100. Each row comes back ready, reactivate or rejected. If a row needs attention, the rest can still proceed.
    Idempotent by emailRe-import or sync nightly, safely. Archived people are matched and reactivated; active duplicates are rejected.
    Skip redone workBulk-assign the assessment to 100 at a time. Already-assessed people are skipped automatically.

    Your agents are first-class readers

    The same spec that renders these docs is what an AI agent reads to answer "can we integrate Thomas, and how?" accurately, on a developer's behalf.
