# Connect OTYS to Hypamoon

Possible, with help from OTYS. The API is documented, but you cannot just create a key: access goes through OTYS first.

Possible

## The check

Three questions about the API of OTYS, answered from its own docs.

**Public API docs**\
**Yes.** Two APIs: the older OTYS Web Services (OWS, public PDF manual) and the newer REST Web API with public Swagger docs. [Read the docs](https://webapi.otys.app/api/integration-guide)

**A key you create yourself**\
**No.** For the Web API you request a key through a support ticket or your Customer Success Manager, and notify OTYS two weeks before going live. [helpdesk.otys.com](https://helpdesk.otys.com/docs/web-api)

**Versions or a changelog**\
**Not confirmed.** The Web API has no version in its paths and no changelog; the OWS manual itself is versioned. [webapi.otys.app](https://webapi.otys.app/api/integration-guide)

**How it signs in**\
An API key is exchanged for a session token: Bearer tokens of about 14 hours for the Web API, or a session token via loginByUid for OWS.

**Webhooks**\
**Yes.** It can tell your app when something changes. [webapi.otys.app](https://webapi.otys.app/api/integration-guide)

**Hosting**\
Cloud

**Condition**\
The Web API key is issued by OTYS on request.

## What you can build

Look up vacancies and submit applications from your chat; candidate records are only reachable through the older OWS interface.

Your chat writes it as a Hypamoon adapter from the docs above. Reading starts after you click Allow in the portal, and every write waits for your approval, one call at a time. [How adapters work](https://hypamoon.com/docs/adapters)

### Good to know

-   Your adapter uses a fixed key: you paste it once in the Hypamoon portal, never in the chat, and it only goes to the API host you allow.
-   Web API webhooks carry only an event name and an ID, and failed deliveries are not retried.

## Try it in your chat

First get access from OTYS. Then fill in what to read and write, and send it.

## Tool not listed? Ask the chat to check its API.

The same three checks work for any software. Your chat reads the vendor's own docs and tells you what it found.

> Check if \[software\] has an open API that a Hypamoon adapter can use: public API docs, a key or token I can create myself without asking the vendor, and versions or a changelog. Link the pages you used.
