The check

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

Public API docs
Yes. Read the docs
A key you create yourself
Yes. Create an API key and secret yourself under the API section of the settings; the key gets the rights of the user it belongs to. developer.simplicate.com
Versions or a changelog
Yes. v2 (REST) and v3 (RPC) side by side, with a dated changelog. developer.simplicate.com
How it signs in
An API key and secret you create in Simplicate, sent as Authentication-Key and Authentication-Secret headers (v2) or as a Bearer value (v3). Keys can have an expiry date.
Webhooks
Yes. It can tell your app when something changes. developer.simplicate.com
Hosting
Cloud

In practice

What it takes in a real Simplicate administration.

Getting access
An administrator opens the API section in the general settings, creates a key and secret for a user (best a dedicated user with only the rights needed) and sets an expiry date.
Limits
At least 60 requests per minute; limits can differ per endpoint; HTTP 429 when exceeded. developer.simplicate.com
Writing
Read and write. Create and update records through v2, for example project services, sales and invoices; v3 offers specific commands such as approvals.
Cost
API access is listed among the base features on the pricing page, without a surcharge. simplicate.com

What you can build

A web intake that creates the organization, contact person and a sales opportunity in Simplicate, and a Monday chat summary of hours not yet approved per project.

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

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.
  • Expect at least 60 requests per minute; the API returns HTTP 429 when you go over the limit. Your account address is part of the API URL.

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. Link the pages you used.
