   • New Card Name (Text Input)
   • New Description (Textarea)
2. Add a “Update Card” button.
3. Add the OnClick → Trello → Trello Update Card action.
4. Connect the parameters to the form components via the Symbol Picker.
5. The card information is automatically updated in Trello.

Trello Update Card Advanced Customizations

• Dynamic Update: Only the field that the user fills in can be updated.
• Conditional Usage: If the card is in a specific status, its description can be updated automatically.
• Chain Actions: After the card is updated, a “Card updated” notification can be sent to the team with the Slack Post Message action.

Technical Risks and Controls

• If boardId and cardId are not entered correctly, the update will fail.
• Fields with empty values will not be updated.
• API access permissions must be configured correctly.
