Connect iDoklad to Hypamoon
Yes, with one catch. iDoklad 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.
OpenThe check
Three questions about the API of iDoklad, answered from its own docs.
- Public API docs
- Yes. Documentation is on the developer portal after a free developer registration. Read the docs
- A key you create yourself
- Yes. Apps register themselves on the iDoklad Developer portal to get a client ID and secret; there is also a client credentials flow for your own data. api.idoklad.cz
- Versions or a changelog
- Yes. The API is version 3.0.0 with a version prefix in the path (/v3/) and an FAQ and changelog page. api.idoklad.cz
- How it signs in
- OAuth 2.0 with authorization code, client credentials or a PIN flow, and a bearer access token on every request.
- Webhooks
- Yes. It can tell your app when something changes. api.idoklad.cz
- Hosting
- Cloud
- Condition
- The number of API calls depends on the plan, for example 7,500 a month on Oblíbený and 75,000 on Prémiový for Czech agendas.
What you can build
Issue invoices from your own order flow in iDoklad and match bank payments to them, with your chat answering which invoices are still open.
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
- iDoklad signs in with OAuth or signed requests only, with tokens that expire. The Hypamoon vault holds a fixed key today, so an adapter for iDoklad takes more work: ask your chat to check this first.
- Webhooks, attachments, tags and e-invoices are covered by the API. Call limits are per month and depend on your iDoklad plan.

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.
Fill in the name of your software. Checking needs no connection to Hypamoon.
