Does Tickr have a public API?

Short answer

Yes — under /api/v1/..., authenticated by API key. Full documentation is published at /en/api/.

Details

The public API covers:

Time entries: read, create, edit, delete and bulk upsert.
Timers: start, stop, list running timers.
Projects, tasks, tags and clients: read-only.
Cursor pagination (entries, clients), RFC 7807 errors, per-key rate limiting.

To get started:

Create an API key from Integrations → API keys → Create key (illustrated walkthrough: Personal API keys). Every active workspace member can create their own keys:
- Key role: at most your own role, never Owner. For the MCP connector, pick Workspace User (recommended). An Analyst can only create Analyst (read-only) keys, and a Workspace User cannot create Analyst keys.
- Expiry: 30 days, 90 days (default), 1 year or never.
- Shown once: the key is only displayed when it is created. Copy it right away; nobody can display it again.
- Limits: 10 active keys per workspace and per person; 10 creation attempts per hour (rejected requests count too).
- An email notifies you every time a key is created on your account (it never contains the key), when email is configured.
- Owners and Admins can see and revoke every key in their workspace; other members only see their own.
- Your keys for a workspace are revoked if you leave it, are removed from it, or it is deleted.
- After a password reset through the emailed link, all sessions and all your API keys, in every workspace, stop working immediately: sign in again, then create new keys. Changing your password from your Profile revokes nothing.
