Basecamp Work and projects # Connect Basecamp to Hypamoon Yes, with one catch. Basecamp has an open API that you can use yourself, but it signs in with OAuth only, and that takes more work in a Hypamoon adapter today. Open ## The check Three questions about the API of Basecamp, answered from its own docs. **Public API docs**\ **Yes.** [Read the docs](https://github.com/basecamp/bc-api) **A key you create yourself**\ **Yes.** Register your own app at launchpad.37signals.com/integrations to get a client ID and secret. [github.com](https://github.com/basecamp/bc-api/blob/master/sections/authentication.md) **Versions or a changelog**\ **Yes.** The API docs are kept in a public repository with a full change history; the API host carries the generation (3.basecampapi.com). [github.com](https://github.com/basecamp/bc-api/commits/master) **How it signs in**\ OAuth 2.0 only; access tokens last two weeks and are renewed with a refresh token. **Webhooks**\ **Yes.** It can tell your app when something changes. [github.com](https://github.com/basecamp/bc-api/blob/master/sections/webhooks.md) **Hosting**\ Cloud ## What you can build Add to-dos or messages to a project from your chat, and get a message when someone completes a to-do. 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 - Basecamp signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for Basecamp takes more work: ask your chat to check this first. - There are no API keys, so a connection always runs on OAuth with refresh tokens. Every request needs a User-Agent with your app name and contact. ## Try it in your chat Fill in what to read and write, and send it.

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. Say this in your chat > 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.
