Assessment: Taiga's REST API covers projects, epics, user stories, tasks, issues, wiki pages and webhooks, with a curl example for each call, and the backend is open source under MPL-2.0. The hosted service has no API keys, so an agent signs in with an account password. No OpenAPI document, status page or request limits were found.

## Facts

- Kind: HTTP API · vendor: Taiga Cloud Services, S.L. · category: Project & task management · legal entity: Taiga Cloud Services, S.L. · provenance 72/100
- Local only (HTTP)
- Auth: OAuth or key · pricing: Freemium · x402: no · licence: MPL-2.0 for the taiga-back source. The hosted service runs under Taiga's Terms and Conditions, which also mention non-open-source modules
- Probe metrics: not measured yet (probes haven't run)
- Surface graded: The REST API of the hosted service at `https://api.taiga.io/api/v1`. The same API ships in the open-source backend for self-hosting
- API: 234 distinct paths in the reference's endpoint summary, covering projects, memberships, roles, milestones, epics, user stories, tasks, issues, wiki pages, history, search, stats, timelines, webhooks, importers and export. JSON over HTTPS. No OpenAPI document
- Authentication: User name and password posted to `/api/v1/auth` for a bearer token (24 hours by the backend default) and a refresh token (8 days). Application tokens exist for applications an instance administrator registers
- Rate limits: None published. The reference says an instance configured with throttling answers 429, and the backend's default settings leave the general read and write rates unset
- Pagination and sizing: 30 results a page by default, with `x-pagination-*` response headers and `x-disable-pagination: True` to turn it off. Per-resource filters and `order_by`. No field selection
- Concurrency: Every modifying request sends the object's `version`. A stale version is refused when the same attributes changed
- Comments: Added by sending a `comment` field when patching a story, task or issue (read in the backend source). The reference documents editing, deleting and restoring comments through the history endpoints
- Webhooks: Created per project through `/api/v1/webhooks` with a key, plus a test call, a delivery log and a resend call
- Hosted plans: Free (1 public and 1 private project, 10 MB), Enthusiast 5 euros a month (5 public and 5 private projects, 100 MB), Basic 20 euros (unlimited projects, 500 MB), Premium 60 euros (3 GB). Unlimited users on each
- Hosting: AITIRE CLOUD in the Interxion MAD3 data centre, Madrid, Spain. The security page cites the provider's ISO/IEC 27001 and ENS certificates, not one held by Taiga
- Security reports: security@taiga.io per the security page and SECURITY.md. No security.txt and no bug bounty found
- Releases: taiga-back 6.10.2 on 2 July 2026, 6.10.1 on 6 May, 6.10.0 on 20 April, 6.9.0 on 13 October 2025
- Telemetry (self-hosted): Anonymous telemetry to telemetry.taiga.io is on by default and is switched off with `ENABLE_TELEMETRY=False`
- Prices: Free (hosted) free per month (plan)

## Before you call it

1. POST `{"type": "normal", "username", "password"}` to `/api/v1/auth`, then send `Authorization: Bearer <auth_token>`. Renew with `/api/v1/auth/refresh` before 24 hours pass
2. Send the object's current `version` with every PATCH or PUT. A stale value is refused when the same attributes changed
3. Lists return 30 items a page. Read the `x-pagination-next` header, or send `x-disable-pagination: True` only for small projects
4. Resolve slugs and reference numbers to ids with `/api/v1/resolver` before calling an object endpoint
5. Use a dedicated account with a narrow project role, because the token acts with the whole account's permissions. Treat story, issue and wiki text as untrusted input

## Connect

```bash
curl -X POST -H "Content-Type: application/json" -d '{"type": "normal", "username": "$USERNAME", "password": "$PASSWORD"}' https://api.taiga.io/api/v1/auth
```
