Markdown to HTML API + Trello Integration

Why connect them

The Markdown to HTML API in Trello.

Trello makes project management visual and intuitive. Integrating APIs with Trello enables automated card creation, intelligent task enrichment, and data-driven boards. Keep your projects updated with real-time external data.

What you can build

Workflows worth wiring.

Automatically create cards for new support tickets with enriched customer data

Update card descriptions with the latest status from external systems

Create task checklists based on data validation results

Move cards automatically when external conditions change

Templates

Ready-made ideas.

New card created Convert markdown description → add html as comment

Convert card descriptions from Markdown

When a Trello card is created with a Markdown description, convert it to html and add the rendered version as a comment.

Card moved to list Convert markdown → attach html to card

Render Markdown content on card move

When a card moves to a publish list, convert its Markdown description to html and attach the rendered content for review.

Setup

Connect it in a few steps.

Set up with Zapier

1
Set the trigger. Create a Zap with Trello as the trigger app and "New card" as the event. Connect your account.
2
Add the API action. Add APIVerve as the action, select the Markdown to HTML API, and map your trigger data to the request.
3
Send it back. Add a second Trello action for "Create card" and map the returned fields (like html) into it.
4
Test & turn on. Test the Zap with real data to confirm the mapping, then turn it on.

Set up with Make

1
Add the trigger. Create a scenario and add a Trello module set to "New card". Authenticate your account.
2
Call the API. Add an HTTP module pointing at api.apiverve.com/v1/markdowntohtml with your x-api-key header. Pass the trigger's data as the input.
3
Parse & map. Add a JSON module to read the response, then a Trello module for "Create card". Map fields like data.html into place.
4
Activate. Run once to confirm the mapping, then switch the scenario on and set its schedule.

Set up with n8n

1
Add the trigger node. Start a workflow with a Trello trigger node for "New card" and connect your credentials.
2
Add an HTTP Request node. Point it at api.apiverve.com/v1/markdowntohtml using Header Auth (x-api-key). Feed in the trigger data.
3
Map with expressions. Add a Trello node for "Create card" and reference the response with expressions such as {{ $json.data.html }}.
4
Execute & activate. Execute manually to verify, then activate the workflow for production.
