Connect Claude & ChatGPT to CATS

Ask your AI to find candidates with a certain skill in CATS, add someone to a job's pipeline, or show who is at the interview stage. It can create and update candidates, jobs, companies and contacts, move candidates through pipeline statuses, log calls and meetings and manage to-do tasks. Recruiting admin gets done while you talk about the role.

Try asking

  • “Find candidates with React and Danish in their profile.”

    The AI searches candidates by those terms and lists names, contact details and owners.

  • “Add Maria Holm to the Senior Frontend Developer job.”

    It finds the candidate and the job and adds her to the job's pipeline.

  • “Who is in the pipeline for the Senior Frontend Developer job, and at which stage?”

    It lists the candidates in the job's pipeline with their current status.

What your AI can do

Candidates

Search, read, create and update candidates, see which jobs they are in and log calls, emails, meetings and notes.

Jobs and pipelines

Create and update jobs, change job status, add candidates to pipelines and move them from status to status.

Companies, contacts and tasks

Search and manage client companies and hiring contacts, and create or complete to-do tasks.

  • “Move Maria to interviewing.”

    It looks up the statuses her pipeline can move to and changes it to the interviewing status. Status changes can fire your account's automated triggers.

  • “Log that I called Maria today about the second interview.”

    It logs a call activity on the candidate with today's date and your notes, linked to the job.

  • “Create a job for Nordic Foods: Warehouse Manager in Aarhus, two openings.”

    It finds the company, then creates the job with title, location and number of openings.

Questions

What can the AI do in CATS?

The AI can search, read, create and update candidates, jobs, client companies and contacts. It can add candidates to a job's pipeline, move them between pipeline statuses, change job status, list and log activities on candidates, and list, create and update to-do tasks. It can also list users, job statuses and pipeline statuses.

Does the AI see my CATS API key?

No. Your CATS credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start with read-only tools. Moving a candidate to a new pipeline status can fire your account's automated triggers, so that action can require your approval before it runs. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own CATS account.

Does my old CATS API key work?

No. HeyMyApps uses the CATS v3 API, which needs a v3 API key. Transaction codes from the old API do not work. You create a v3 key on the Administration settings page in CATS.
