Trello

Use Trello's REST API for boards, lists, and cards.

Setup

If credentials are not already configured:

1. Get the API key from https://trello.com/app-key
2. Generate a token from the same page
3. Export:

   export TRELLO_API_KEY="..."
   export TRELLO_TOKEN="..."
   

Do not print the raw token back to the user.

Before API calls, write a private temp curl config and register cleanup so secrets stay off the shell command line and the auth file is removed on exit:

AUTH_CURL="$(mktemp)"
chmod 600 "$AUTH_CURL"
trap 'rm -f "$AUTH_CURL"' EXIT INT TERM
cat >"$AUTH_CURL" <<EOF
data = "key=$TRELLO_API_KEY"
data = "token=$TRELLO_TOKEN"
EOF

Common Operations

List boards:

curl -s -G "https://api.trello.com/1/members/me/boards" -K "$AUTH_CURL" | jq '.[] | {name, id}'

List lists in a board:

curl -s -G "https://api.trello.com/1/boards/BOARD_ID/lists" -K "$AUTH_CURL" | jq '.[] | {name, id}'

List cards in a list:

curl -s -G "https://api.trello.com/1/lists/LIST_ID/cards" -K "$AUTH_CURL" | jq '.[] | {name, id, desc}'

Create a card:

curl -s -X POST "https://api.trello.com/1/cards" -K "$AUTH_CURL" \
  -d "idList=LIST_ID" \
  -d "name=Card title" \
  -d "desc=Card description"

Move a card:

curl -s -X PUT "https://api.trello.com/1/cards/CARD_ID" -K "$AUTH_CURL" \
  -d "idList=NEW_LIST_ID"

Comment on a card:

curl -s -X POST "https://api.trello.com/1/cards/CARD_ID/actions/comments" -K "$AUTH_CURL" \
  -d "text=Your comment here"

Rules

• Resolve the board and list IDs before creating or moving cards.
• Read first, write second.
• Confirm before archival or bulk card moves.
• Keep API key and token out of logs and tracked files.
• If you are done before the shell exits, run rm -f "$AUTH_CURL" and trap - EXIT INT TERM.
• Use jq to keep list and search output readable.
