Users are associated with an organization. - **Roles** — The Role object represents a role of a User. - **Users** — The User object represents a User. ### Unified Ticketing API - **Attachments** — Attachments are the files associated with a ticket or a comment. - **Collections** — Tickets and contacts can be grouped into Collections. Collection resource usually maps to the various grouping systems used in the underlying product. Some examples are lists, projects, epics, etc. You can differentiate between these grouping systems using the type attribute of a Collection. - **Comments** — Comments represent the communication happening on a Ticket, both between a User and a Contact and the internal things like notes, private comments, etc. A Ticket can have one or more Comments. - **Organizations** — Organization represents the company or the entity using the ticketing system. An Organization can have one or more Workspaces and Users. - **Tags** — Tags represent a common classification approach used in various ticketing systems. A Ticket may have one or more Tags associated with them. - **Task Lists** — Task Lists represent a collection of Tasks on a Ticket. - **Tasks** — Task represent a smaller subdivision of a Ticket, which could be the list of things to do in a Ticket. - **Ticket Status** — Ticket Status represents the completion level of the Ticket. Some products provide customizing the Ticket Status. - **Tickets** — Core resource which represents some work that needs to be carried out. Tickets are usually mapped to issues, tasks, work items, etc. depending on the underlying product. - **Workspaces** — Workspaces represent the top-level subdivision in a ticketing system. They usually have their own set of settings, tickets, statuses, priorities and users. Some of the usual terminologies used by the products for the top-level subdivision are projects, bases, spaces, workspace, etc. A Workspace could belong to an Organization. ### Unified Search API - **Search** — Search endpoint for all the apps. ## How it works 1. **Link your customer's Trello account.** Use Truto's frontend SDK; we handle every OAuth and API key flow so you don't need to create the OAuth app. 2. **Authentication is automatic.** Truto refreshes tokens, stores credentials securely, and injects them into every API request. 3. **Call Truto's API to reach Trello.** The Proxy API is a 1-to-1 mapping of the Trello API. 4. **Get a unified response format.** Every response uses a single shape, with cursor-based pagination and data in the `result` field. ## Use cases - **Sync tickets between your platform and your customers' Trello boards** — If your SaaS product manages tasks, bugs, or requests, your users expect those items to flow into the tools they already use. Offering a Trello integration lets their teams track work on familiar Kanban boards without leaving your product behind. - **Push contextual updates into Trello cards automatically** — SaaS companies in support, QA, or CRM need to enrich Trello cards with comments, attachments, and metadata as events happen in their platform. This keeps the end-user's Trello workspace up to date without manual copy-paste. - **Read Trello boards and cards to power dashboards or time tracking** — Products that aggregate work data — capacity planners, time trackers, reporting tools — need to ingest a user's Trello boards, lists, and card assignments. Truto's Unified Ticketing API provides a consistent way to query this data across providers. - **Map Trello lists to workflow statuses in your product** — Trello uses lists as implicit statuses rather than a dedicated status field. SaaS companies building status-sync features need to let end-users map Trello lists to internal stages, requiring reliable access to boards, lists, and card-move events. - **Offer Trello as one of many ticketing destinations without per-provider engineering** — B2B SaaS companies that already support Jira or Asana can add Trello through Truto's Unified Ticketing API using the same data model, avoiding the cost of learning another bespoke API and maintaining separate auth flows. ## What you can build - **One-click escalation to Trello** — Let your users create a Trello card on a chosen board and list directly from your app, pre-filled with relevant context like descriptions, tags, and attachments. - **Two-way ticket status sync** — Keep your app's ticket status in sync with Trello list positions so that when a card moves to 'Done' in Trello, the linked record in your product updates automatically. - **Automated comment thread mirroring** — Post new comments on a Trello card whenever a customer reply, internal note, or status change happens in your platform, giving the Trello user full context without switching apps. - **Board and list picker for integration setup** — Build a setup wizard that queries the user's Trello workspaces, boards, and lists so they can configure exactly where new cards should land and which list represents each workflow stage. - **Task import for time logging or capacity planning** — Pull all cards assigned to a connected user across their boards and surface them as selectable items in your time tracker, resource planner, or reporting dashboard. - **Attachment and file sync to Trello cards** — Automatically attach files — screenshots, contracts, logs — to Trello cards created or updated through your integration, so the end-user's team has everything in one place. ## FAQs ### How does Truto handle authentication with Trello? Truto manages the full OAuth flow for Trello on your behalf. Your end-users authorize their Trello account through Truto's embedded auth experience, and Truto stores and refreshes tokens so you never handle credentials directly. ### How does Trello's data model map to the Unified Ticketing API? Trello Workspaces map to Workspaces, Boards map to Collections, Lists map to Task Lists (and can represent Ticket Status), Cards map to Tickets/Tasks, Labels map to Tags, and Card Members map to Users. Comments and Attachments map directly to their unified counterparts. ### Trello doesn't have a formal 'status' field — how do I track card status? In Trello, a card's position on a List is its de facto status. Through Truto's Unified Ticketing API, you can query Task Lists and Ticket Status resources to determine which list a card belongs to, and use that to drive status logic in your product. ### Does Truto handle Trello's API rate limits and pagination? Yes. Truto abstracts away Trello's rate-limiting behavior and pagination mechanics. You make standard requests against the Unified API and Truto manages retries, backoff, and cursor-based pagination under the hood. ### Are there pre-built tools for Trello, or is it built on request? Trello integration through Truto is currently built on request. The Unified Ticketing API data model (Workspaces, Collections, Tasks, Tickets, Comments, Attachments, Tags, Task Lists, Ticket Status) defines the schema, and Truto's team configures the Trello-specific mapping when you request it. ### Can I access Trello user and organization data beyond ticketing? Yes. Truto also offers a Unified User Directory API that covers Organizations, Roles, and Users. This lets you resolve Trello board members, map them to users in your product, and assign cards to the right people programmatically.
