Trello Comment Component

Trello Comment Component connects your flow to your Trello account to work with the comments of a card: write a new comment, see all the comments of the card, change a comment’s text, or delete it.

It is useful to record on the card itself what happens outside Trello, such as a customer’s reply or the result of a process, and to let an agent read the conversation of a task before acting.

When to use it

  • A customer replies to an email and you want the reply to be added as a comment on the case card.
  • An automatic process finishes and you want to note the result on the matching card.
  • An AI agent must read a card’s comments to summarise the status of a task.
  • You want to correct or remove a comment that the flow itself wrote.

Configuration

You need a Trello Task API credential with your Trello account’s token and API key. See Credentials.

FieldWhat it does
Credential (required)The Trello Task API credential used to access your account.
OperationWhat the component does. See Operations. Default: Create.
Card ID (required)The card’s ID. Used in every operation.
Comment ID (required)The comment’s ID. Only in Update and Delete.
Comment Body (required)The comment’s text. Only in Create and Update.

Operations

OperationWhat it does
CreateAdds a comment with the given text to the card.
Read AllReturns all the comments of the card.
UpdateChanges a comment’s text.
DeleteDeletes a comment from the card.

Output

The Data output returns the comment you worked with as Trello stores it: its ID, the text, the date and who wrote it, among other details. With Read All you get one item per comment. Delete returns a confirmation.

The component can also be connected to an Agent as a tool, so the agent decides when to comment or read comments. See Tool Mode.

Example

A technical service wants every visit report to be noted on the card of the fault.

  1. The technician sends the report from a form with the card ID and what was done.
  2. Add Trello Comment Component with the Create operation.
  3. In Card ID enter the card’s ID and in Comment Body the report text, for example Visit done: thermostat replaced. Waiting for the customer to confirm.

Good practices

  • To change or delete a comment you need its ID: look it up with Read All on the card.
  • Comments are posted on behalf of the credential’s account. If several flows comment, start the text saying where it comes from, so the team knows who wrote it.
