Trello Cards

Move a Card — Document Gets Sent

Move a Trello card to the 'Send for Signature' list and Zignature automatically sends the right document — the card name, description, and custom fields populate the template.

  • List move trigger — Move card to 'Needs Signing' list → document dispatched.
  • Card data auto-fill — Card title and description fields populate document template.
  • Label triggers — Apply a Trello label → trigger specific document type.

Move a Card — Document Gets Sent

Trello card moved to configured list → Zignature document sent automatically.

Included on all plans
Trello Butler

Automate With Trello Butler Rules

Use Trello Butler automation rules to trigger Zignature document dispatch — no Zapier account needed. Butler's 'call webhook' action fires Zignature's API when any rule condition is met.

  • Butler webhook action — Butler rule triggers Zignature API call directly.
  • No Zapier required — Butler's built-in automation handles the trigger.
  • Complex conditions — Multi-condition Butler rules for sophisticated document logic.

Automate With Trello Butler Rules

Trello Butler automation rules call Zignature webhooks for no-code integration.

Board Visibility

Contract Pipeline Visible as Trello Lists

Use Trello lists to represent your contract stages — Preparing, Sent, Signed, Archived. Cards move through lists based on signing events, giving a visual contract pipeline.

  • Visual pipeline — Contract stages as Trello lists — Sent, Viewed, Signed, Declined.
  • Auto card move — Signing completion moves card to 'Signed' list automatically.
  • Card attachments — Signed PDF attached to Trello card on completion.

Frequently Asked Questions

Everything you need to know.

How do I trigger a Zignature document from a Trello card?

Two options: Zapier (Trello trigger: card moved to list) fires a Zignature API call, or Trello Butler automation rules use the 'call webhook' action to trigger Zignature directly — no Zapier account needed for Butler.

Can Trello card data auto-fill Zignature document templates?

Yes. Map Trello card name, description, and custom field values to Zignature template variables via Zapier field mapping. Basic fields (name, assignee email) are available on all plans; custom fields require Trello Standard or above.

Can a signed document automatically move a Trello card?

Yes. Configure a Zignature completion webhook to trigger Zapier, which moves the Trello card to the 'Signed' list and attaches the signed PDF to the card.

Does Trello Butler have a native Zignature integration?

Trello Butler supports webhook actions — you can call Zignature's REST API directly from Butler rules without Zapier. This is the most lightweight integration option for Trello users.

Can I use Trello for managing contracts across multiple clients?

Yes. Create a Trello board per client or a single board with labels per client. Each card is a contract — moving through Preparing, Sent, Signed, and Archived lists with Zignature driving the signing workflow.

Does this work with Trello Free?

Basic Zapier integration works with Trello Free. Trello Butler webhook actions (for no-Zapier integration) require Trello Standard or above. Custom fields for data mapping require Trello Standard.
