Trello
Business appsAPI keyConnection test available
Create cards in Trello (API key + token).
OCNORA ships 25 typed Trello operations and 1 trigger. Each node has a schema-driven form, input and output tables beside its settings, and is pre-flighted by Workflow Health before your first real run.
Before you connect Trello
- Authentication
- API key
- Credential
- the Trello api_key + token pair, plus "api_secret" — the application secret Trello signs webhook deliveries with{"api_key", "token"}
- Connection test
- Available: the stored credential can be checked against the provider when you add it. This is not a record that a test was run or passed.
- Prerequisites
- The token must be able to administer webhooks; a read-only token registers nothing. Publishing also needs MANTLE_APP_PUBLIC_BASE_URL set to an https URL Trello can reach — Trello runs a HEAD request against the callback before it will create the webhook, and refuses a URL with an invalid TLS certificate.
Prerequisites are taken from the connection notes in this provider’s node contracts; each node’s reference page says which apply to it.

A sample Trello workflow
- 1Eventtrigger.trello_eventStart a run when a Trello board, list, card or member changes. Publishing creates a webhook in the tenant's own Trello account, scoped to the connection's token; disabling or unpublishing deletes it.
- 2Get Card Attachmentstrello.get_attachmentsList every attachment on a card.
- 3Add Attachment to Cardtrello.add_attachmentAttach a URL to a card, optionally using it as the card's cover image.
An outline built from this provider’s node contracts, not a recorded run. Each step’s output fields are available to the next in the field picker.
Every node below has a reference page: what it does, the connection it needs, its config fields with types, constraints and examples, and the shapes it emits.

Trello questions
- How does OCNORA authenticate with Trello?
- With a stored API key credential, shaped the Trello api_key + token pair, plus "api_secret" — the application secret Trello signs webhook deliveries with or {"api_key", "token"}. A connection test can check it when you add it.
- What can I automate with Trello?
- 25 typed operations and 1 trigger, each with a reference page listing its config fields and the shapes it emits.
- What if the Trello operation I need is not listed?
- Where Trello has an HTTP API, call it from the HTTP node with the same credential, or describe the step to the AI builder, which asks our team for a typed node when one is missing.
- Are there templates that use Trello?
- Not yet. Start from a blank workflow, or describe the workflow to Build with AI.
- How are Trello calls controlled?
- Every call and every run step is audited, runs count against the execution budget, and Workflow Health pre-flights the workflow when you save it.
