Send website inquiries to a Trello board

6 min read Updated Nov 8, 2026

If your work lives on a Trello board rather than in a CRM, each inquiry can arrive there as a card at the top of the list you choose, named after the person, with their message and details already in the description. Drag it along the board like any other job.

The inquiry still lands in your Webkio Inbox too. The shared rules, what is never sent, how failures are retried, are on Send your website inquiries to your CRM. This page is the Trello part.

What you need

Field Where it is
API key Go to trello.com/apps/admin. If you have no Power-Up there, create one; it is only a container for the key, and nothing is installed on your board. Open it, go to the Trello Auth tab, and generate an API key.
Token On the same tab, next to the key, click the Token link and Allow access. Copy the long value Trello shows.
List id See below.

The token acts as you on every board you can see, which is why it is stored encrypted and never shown again. The key on its own does nothing; it is an identifier and stays visible.

Finding a list id

Trello does not show list ids in its interface. Two ways to get one:

  • Open the board, add .json to the end of its address in the browser (so trello.com/b/AbCdEf12/jobs.json), and search the page for "lists". Each list has an "id" of 24 characters and a "name".
  • Or open any card in the list, add .json to its address, and read "idList" in that page.

Setting it up

  1. Project settings > CRM, choose Trello under Task boards.
  2. Enter the key, the token and the list id.
  3. Tick which inquiries to send.
  4. Add destination, then Send test.

No field mapping: a card is a thing to read, not a record with columns.

What the card contains

On the card From the inquiry
Title What happened and who: "Website inquiry: Ada Lovelace". With no name, the email address.
Description Their message first. Then Email, Phone and Company on their own lines, then any extra fields the form collected (a budget, a job type), then a last line saying which form, which site and which page.
Position Top of the list, so the newest inquiry is always the first card.

The card is created with one call to Trello's cards endpoint, authorized with your key and token, and Trello answers with the card. A green result means it is on the board.

What it will not do

Labels, members, due dates. The card arrives bare. A Trello Butler rule on "when a card is added to list ..." can add any of those with your defaults.

Update a card. A second inquiry from the same person is a second card.

Attachments. Nothing a visitor uploaded travels; the card links to nothing but the page they wrote from, in text.

Archived lists. A card can be added to a list that is archived, and it will be invisible until the list is restored. Use an open list.

When something fails

Trello answers failed calls with a short plain-text message, and the destination card shows it.

What the destination shows What it means What to do
invalid key The API key is wrong. Copy it again from the Trello Auth tab. It is 32 characters of letters and digits.
invalid token The token is wrong, or it has been revoked. Trello tokens can be revoked from your account's Settings page, and are revoked when the Power-Up that issued them is deleted. Generate a new token from the Token link and paste it in.
invalid value for idList The list id does not exist, or the token's user cannot see that board. Re-read the id from the board's .json, and make sure the account that made the token is a member of the board.
unauthorized permission requested The token was issued read-only. Generate the token again and allow write access when Trello asks.
A 429 answer Trello's rate limit. Retried by itself.
Accepted, but no card Look at the top of the list named by that id. If the board has filters on, clear them.

Four consecutive failures pause the destination; Resume once the value is fixed.

Frequently asked questions

Can inquiries go to different lists by form?

Add one destination per list, each ticking the inquiries it should carry. Property inquiries to one list and contact forms to another is two destinations.

Can the card be assigned to someone?

Not by us. A Butler rule on the list can assign a member, add a label or set a due date the moment the card arrives.

Does the description render formatting?

Yes. Trello renders Markdown in descriptions, and the field labels are bold so the details are easy to scan.

Is the token safe to paste here?

It is stored encrypted and never displayed again, and the pattern check refuses anything that is not shaped like a Trello token. If you ever want it gone, revoke it in Trello and the destination stops with a clear error.

Why not a Trello Power-Up?

A Power-Up runs inside Trello's interface and adds buttons there. This is the other direction, data into Trello, and a card write needs no Power-Up at all; the one you create is only where Trello hands out keys.

What is the "Webkio Test" card?

From Send test. Archive it.
