Batched: pass every source string and every target language in one call. Each TM's own `minMatchPercentage` and penalty settings (case / whitespace / trailing punctuation) are applied, so `matchPercentage` is the net score after penalties. See the [translation memory guide](/docs/guides/translation-memory). **Constraints:** - Returns an empty object when translation memory is disabled for the org or the project. - At most 100 source texts and 50 languages per request; up to 10 matches per language. ## OpenAPI ````yaml /openapi/textsetu.json post /projects/{projectId}/tm/matches openapi: 3.1.0 info: title: TextSetu API version: 1.2.0 description: >- Public REST API for TextSetu. Authenticate with a Personal Access Token (tsu_pat_…) or a project token (tsu_proj_…) via the `Authorization: Bearer ` header. **Authorization is permission-based.** Every token carries an explicit allow-list of RBAC permission keys (e.g. `translation_read`), and each endpoint declares the permission it requires (`x-permission`). A token's effective access is its underlying authority ∩ its allow-list — a PAT is further bounded by its owner's role-based permissions, so it can only narrow, never exceed, what the owner already has. A project token is bound to a single project. There are no coarse read/write/manage scopes. **Response envelope.** Every endpoint returns `{ "success": true, "data": … }` on success and `{ "success": false, "error": { "code", "message" } }` on failure. **Rate limit.** 600 requests/minute, keyed by token (or by IP when unauthenticated). Exceeding it returns 429 with the standard error envelope. servers: - url: https://api.textsetu.com/api/v1 description: Production - url: /api/v1 description: This server (self-hosted / same-origin) security: - bearerAuth: [] tags: - name: Projects description: >- Read project metadata — settings, key separator, and the approval/branching flags that shape how the other endpoints behave. - name: Languages description: >- List and manage a project's target languages. Each language is referenced by its BCP-47 code; the source language is flagged separately. - name: Translations description: >- Manage a project's translations: create, read, update, and delete translation keys — the identifiers your app looks up, carrying metadata (description, tags, screenshot) — and set the translated value for a key in a given language. Value writes honor the project's approval workflow — non-approver writes land as `pending_review`. - name: Stats description: >- Per-language completeness and approval progress for a project — the numbers behind the dashboard. - name: Import/Export description: >- Bulk-load source files into a project or export the current translations. Supports the same file formats as the web app. - name: Branches description: >- Work on translations in isolation and merge them back. Branch reads/writes mirror the main endpoints but stage changes as a diff until merge.

See the [translation memory guide](/docs/guides/translation-memory). - name: AI description: >- Machine-translate a project with the org's configured AI engine (brand voice, glossary/TM grounding, and an optional review pass). Runs asynchronously — start a run and poll the returned `jobId`. - name: Webhooks description: >- Get notified when a project's translations change, instead of polling. Register an HTTPS endpoint, subscribe it to the events you care about, and TextSetu POSTs a signed payload whenever one occurs. Payloads follow the [Standard Webhooks](https://www.standardwebhooks.com) spec — verify the `webhook-signature` header with any compatible library. Delivery is at-least-once and unordered, so treat `webhook-id` as an idempotency key. Failed deliveries are retried five times over roughly seven hours, and every attempt is inspectable and replayable via the delivery log. - name: Meta description: Service-level and cross-cutting endpoints. paths: /projects/{projectId}/tm/matches: post: tags: - Translation Memory summary: Get fuzzy TM matches description: >- Fuzzy-match source strings against the translation memories that apply to this project, returning scored suggestions.
