Integrations & API

Make Lily the ATS, or make your ATS much more useful.

Lily can run the complete hiring journey or add conversational screening and automation to an existing recruitment stack. Publish vacancies to thousands of job boards, connect your AI tools through our MCP server, and move data through a documented API, never by re-keying.

Two ways to run Lily

Should Lily replace your ATS, or connect to it?

Replace

Use Lily as the central ATS and system of record

Run the complete hiring journey in one platform: careers pages, job distribution, pipelines, screening, interviews, compliance, offers and onboarding. Your recruitment data lives in one place, and Lily's autopilot does the work between the stages.

One system of record for every vacancy and candidate
Autopilot screening, interviewing and follow-up built in
Multi-site permissions and reporting from day one
Connect

Use Lily alongside your established ATS

Keep your existing applicant tracking system and add Lily as the intelligent screening and interview layer. Candidates flow in, Lily screens and interviews them, and structured results flow back to the system your team already uses.

Add conversational screening and structured interviews
Candidate data and outcomes flow back without re-keying
Job board reach

Publish once. Appear everywhere candidates look.

Lily's multi-posting engine distributes every vacancy to thousands of UK job boards from a single publish (Indeed, Totaljobs, GOV.UK's Find a job, Reed.co.uk, CV-Library and many more), with every application flowing back into one pipeline and source-to-hire tracking on each board.

AI-native integration

Plug Lily straight into Claude, ChatGPT and your AI tools.

Lily ships with an MCP (Model Context Protocol) server, the open standard that lets AI assistants use real systems. Connect it to Claude, ChatGPT or any MCP-compatible tool and your recruitment runs from wherever your team already works: totally automated, fully audited.

Ask your assistant about your pipeline

See who needs attention, check a candidate's progress or pull hiring stats in plain English, straight from Claude, ChatGPT or the AI tool your team already uses.

Take action without opening another tab

Move applications forward, book interviews, request references and send offers from the same conversation. Lily does the work; your assistant drives it.

Build agents on top of Lily

Any MCP-compatible tool or agent framework can drive your recruitment workflows, with the same permissions, safeguards and audit trail as a member of your team.

Prefer code to conversation? Everything the MCP server can do is also available through Lily's documented REST API and real-time webhooks: same data, same permissions, your choice of interface.

Under the hood

What can your team build on Lily?

Documented API

A fully documented external API (OpenAPI) for your developers: pull candidates, hires and compliance data into any system you run.

MCP server

Connect Lily to Claude, ChatGPT and any MCP-compatible assistant or agent, and automate recruitment through natural conversation.

Candidate data movement

Move candidate records between Lily and the systems around your workforce without manual re-entry.

Job and application flows

Bring vacancies in, send applications on, and keep the pipeline consistent wherever a candidate first applied.

Status updates

Keep stages in sync, so a candidate's progress in Lily is reflected in the systems your team works from.

Webhooks for every event

Real-time webhooks with delivery tracking for every hiring event: new applicant, screening complete, offer signed, checks passed.

Security and permissions

Role-based access controls what each integration and user can see, with a clear audit history of recruitment actions.

Implementation

How does an integration happen?

1

Map your stack

We start with the systems you run today (your ATS, HR and workforce tools) and what needs to move between them.

2

Agree the data flows

Together we define which jobs, candidates, statuses and outcomes flow in each direction, and who has access to what.

3

Connect and verify

Your technical team works with ours using the documented API and webhooks, and we verify the flows before anything goes live.

Discuss your recruitment stack.

Tell us what you run today and whether you want Lily to replace it or work alongside it. We'll map the shortest route.
