A hire with no card
Nobody made it.
Greenhouse to Trello automation for small teams that run hiring on a board
Greenhouse to Trello automation that turns approved offers and hires into cards with checklists, members and due dates, and keeps them in step inside Trello's limits
Trello allows 300 requests per 10 seconds per API key and 100 per 10 seconds per token and says in the 429 which limit was hit, and recommends webhooks over polling. BoldBellows notes the application ID, the job and the target board before a card is touched, reads Trello's rate headers and prefers its webhooks to polling, then creates one card per approved offer or confirmed hire on the right board and list, adds the standard checklist, assigns the members you name, sets the due date from the start date, moves the card when Greenhouse changes, and archives it if the hire is reversed. Nothing about compensation or demographics goes onto a card.

- A fee you can file from $415, billed once, with the handover pack included at no extra cost
01 · the by-hand card problem
The onboarding card is made when someone remembers to make it
Small teams run hiring and onboarding on a board, and the board is only as good as whoever remembered to add the card. A start date that moves leaves the due dates wrong, a reversed hire has a card nobody archives, and the checklist is a copy of the last hire's with their name still in it. Polling for changes burns the per-token budget when a webhook would do.
Due dates from the last hire
Cards were copied.
A start date that moved
The card was not updated.
- A repeated notice writes the card again
- Cards are made by hand and copied for Greenhouse to Trello
- A moved date is fixed if someone notices with Greenhouse to Trello
- A second delivery lands on the same card through the Greenhouse application ID, tied to its Trello card
- Each hire gets one card with a checklist
- Dates follow the record and requests stay under the limit
02 · how it works
How Greenhouse offers and hires become cards with checklists, members and dates
First the change is judged, then identified, then matched and written, in that Greenhouse order every time.
- 01
Verify and admit
Each Greenhouse event is authenticated, stamped, and admitted only if it meets the rule you wrote.
- 02
Read, match, create
Offers and hires are read, matched on the application ID, and turned into cards with a checklist and members.
- 03
Move, pace, verify
Cards move as the record changes, requests are paced under the limits, and a scheduled check compares the board with Greenhouse.
What the design assumes about Greenhouse and Trello
A hundred per token
Trello allows 300 requests per 10 seconds per API key and 100 per 10 seconds per token and says which limit was hit in the 429, so the route reads the headers and prefers webhooks to polling.
Webhooks over polling
Trello's limit of 100 requests per 10 seconds per token makes polling wasteful, so the route registers webhooks for the boards it watches and reads the rate headers before any bulk change.
Retry discipline
Each retry begins with a lookup in Trello on the Greenhouse application ID, tied to its Trello card; the write is repeated only when nothing is found.

Choosing how Greenhouse reaches Trello: a card made by hand when someone remembers, a zap or a card-per-application sync
Each can create a card. Only one merges by application, sets dates from the record and stays inside Trello's limits.
| The starting signal | a card made by hand when someone remembers | An off-the-shelf Greenhouse-Trello zap | BoldBellows' card-per-application sync |
|---|---|---|---|
| What starts the work | Someone reads the notification | A trigger fires on every match | A Greenhouse event your rule lets through |
| How identity is decided | Whoever notices searches by email | A visible label is trusted as unique | Application ID, tied to the card |
| What reaches Trello | Text typed from memory | Every field, unchecked | One card per hire with checklist, members and due date |
| After an uncertain result | Somebody audits by hand | The failure is retried blindly | Looks up the card, checks its state, repairs or assigns |
An old update lands last
The incoming time is checked against what Trello holds, and an older Greenhouse change is recorded rather than applied.
A hire's start date is pushed back two weeks
The change is read from Greenhouse, the card's due dates and list are updated, the checklist keeps its progress, and no second card is created. A search on the Greenhouse application ID, tied to its Trello card comes first, and what it returns is filed as absent, correct, altered or uncertain. Making a new card is the last resort, used only when the lookup comes back empty.
The first thing agreed is the Greenhouse application ID, tied to its Trello card, and only then are fields chosen and routes drawn.

06 · process & getting started
Six steps from hand-made cards to a board that follows the Greenhouse record
With Greenhouse to Trello in place, a brief becomes a monitored route through six steps with a named output at each stage.
- Step 01
Design the board
On this Greenhouse to Trello route, we map events, lists, checklists and members to a board.
- Step 02
Approve access
We set up read access to Greenhouse and write access to Trello, and choose the keys that link the two.
- Step 03
Agree checklists and rules
Checklist wording, the owner of each event and the rule for a moved date are put in writing before the build.
- Step 04
Try to break it
We replay events, hold them back, strip fields and withdraw access in a safe copy of Trello before anything is live.
- Step 05
Launch with notes
Launch is a planned moment, not a surprise, and the notes you receive cover every rule in force, for this Greenhouse to Trello route.
- Step 06
Follow-through
With Greenhouse to Trello in place, the opening weeks are reviewed against the evidence log with you so early surprises are found, recorded and fixed.
07 · turnaround
How quickly the Greenhouse Trello route ships
Delivery time runs from approved access to both platforms, in the Greenhouse to Trello route.
Launch
4 to 7 business days
Growth
7 to 11 business days
Safeguard
11 to 17 business days
08 · before we start
What the Greenhouse side has to provide
Approval for us to read the agreed Greenhouse objects
Harvest v3 read access, and a Trello board you can connect an app to
Credentials for Greenhouse with read access to the records in scope
Your own list of the Greenhouse events that count and those that do not
A named owner for Trello mapping and exception decisions

09 · security and ownership
No patches to either tool, just the fields on the map
Reads and writes are confined to an agreed list in Greenhouse and Trello, with nothing stored on our side.
No edits to your tools
The connection lives between Greenhouse and Trello; neither product is patched, extended or reconfigured to make it work.
Scoped, revocable access
Access is granted per object and withdrawn in one step, leaving the route inert, for this Greenhouse to Trello route.
Minimum necessary data
The card receives the fields the work needs and nothing else, and private Greenhouse notes are never copied.
Verify, then continue
The route reads the card back from Trello before it decides whether anything still has to be written.
Minimal logging
What gets logged is the Trello event and its result, never the content of a record.
Full handover
On this Greenhouse to Trello route, the documentation is complete enough that another engineer could run the route tomorrow.
