# Connect Chaser to Hypamoon

Yes. Chaser has a public, versioned API and you create the key yourself, so your chat can write the adapter.

Open

## The check

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

**Public API docs**\
**Yes.** Chaser publishes an OpenAPI reference (Chaser API v1.11.1). [Read the docs](https://openapi.chaserhq.com/docs/static/index.html)

**A key you create yourself**\
**Yes.** You get an API key and secret yourself in Chaser under Organisation Settings, Integrations, Get API keys. [openapi.chaserhq.com](https://openapi.chaserhq.com/docs/static/index.html)

**Versions or a changelog**\
**Yes.** The reference carries a version number. [openapi.chaserhq.com](https://openapi.chaserhq.com/docs/static/index.html)

**How it signs in**\
HTTP Basic with your API key and API secret, base64 encoded.

**Webhooks**\
**Not confirmed.**

**Hosting**\
Cloud

## What you can build

Push customers and invoices from your own system into Chaser so reminders go out automatically, and ask your chat which invoices are still being chased.

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.
-   The rate limit is 200 requests per minute. An OpenAPI file can be imported into Postman.

## Try it in your chat

Fill in what to read and write, and send it.
