--- title: ConnectWise PSA API Integration on Truto slug: connectwisepsa category: Ticketing canonical: "https://truto.one/integrations/detail/connectwisepsa/" --- # ConnectWise PSA API Integration on Truto **Category:** Ticketing **Status:** Beta ## How it works 1. **Link your customer's ConnectWise PSA 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 ConnectWise PSA.** The Proxy API is a 1-to-1 mapping of the ConnectWise PSA 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 - **Automate license-based billing reconciliation** — SaaS vendors selling per-seat or consumption-based products (security agents, backup storage, SaaS licenses) can automatically sync active usage counts into ConnectWise Agreement Additions, ensuring MSPs bill their end-clients accurately every month without manual audits. - **Push security alerts as prioritized service tickets** — Cybersecurity and monitoring SaaS platforms can create, update, and auto-close tickets on ConnectWise Service Boards in response to real-time threat detections or infrastructure alerts, giving MSP technicians full diagnostic context without leaving their PSA. - **Sync asset and configuration data into ConnectWise** — IT discovery, endpoint management, or lifecycle tools can push device and software inventory into ConnectWise Configurations, so technicians always have an up-to-date view of a client's environment when working tickets. - **Capture technician time from external tools** — Remote support, project management, or field service platforms can push time entries back to ConnectWise tickets and projects, ensuring every minute of billable labor is recorded for accurate payroll and client invoicing. - **Close the loop on customer satisfaction surveys** — CSAT and quality assurance platforms can listen for ticket closures in ConnectWise, trigger surveys, and write scores and feedback back into ticket notes or custom fields so MSP managers can report on service quality. ## What you can build - **Closed-loop alert-to-ticket pipeline** — Automatically create ConnectWise service tickets from alerts, append diagnostic notes as new data arrives, and close tickets when the issue resolves — all without duplicate ticket noise. - **Dynamic agreement addition sync** — Push real-time seat counts or consumption metrics from your platform into ConnectWise Agreement Additions so MSPs never under-bill or over-bill their clients. - **Configuration inventory push** — Sync discovered devices, installed software, or managed assets into ConnectWise Configurations tied to the correct Company, keeping the MSP's CMDB current. - **Two-way ticket status sync** — Reflect status changes between your app and ConnectWise in both directions so technicians and your platform always show the same ticket state. - **Time entry writeback** — Record session durations or logged work from your product as ConnectWise Time Entries against the relevant ticket or project phase. - **Company-to-tenant mapping UI** — Let MSPs map their ConnectWise Companies to tenants or workspaces in your product during onboarding, establishing the foundation for all downstream data sync. ## FAQs ### How does authentication work with the ConnectWise PSA API? ConnectWise PSA supports API key-based authentication using a public/private key pair tied to a member account, as well as client ID-based access. Truto handles credential storage and auth header construction so your end users simply provide their ConnectWise instance URL and API keys during the connect flow. ### Does ConnectWise PSA enforce rate limits? Yes. ConnectWise applies rate limiting on its REST API. Truto manages request pacing and retry logic so your integration stays within limits without you needing to implement backoff strategies yourself. ### Can I read and write custom fields on ConnectWise tickets or other objects? ConnectWise PSA supports custom fields (called 'Custom Fields' or sometimes exposed via the customFields array on entities like Tickets and Companies). You can read and update them through the API, which is useful for writing back scores, tags, or metadata from your product. ### What ConnectWise PSA entities can I interact with through the API? The ConnectWise REST API exposes a broad set of entities including Companies, Service Tickets, Service Boards, Agreements, Agreement Additions, Configurations, Time Entries, Contacts, Projects, and Notes. Truto can build proxy or unified access to any of these endpoints on request. ### Are there Truto Unified APIs or pre-built tools for ConnectWise PSA? ConnectWise PSA tools and Unified API mappings are built on request. Once requested, Truto handles pagination, auth, error handling, and data normalization so you get a consistent developer experience across ConnectWise and other ticketing or PSA platforms. ### How do I handle pagination when listing large datasets like tickets or companies? The ConnectWise API uses page/pageSize query parameters for pagination. When Truto builds your integration, pagination is abstracted away — you receive complete result sets or cursor-based iteration without manually managing page tokens.
