Turn Markdown into images with Zapier

Use Webhooks by Zapier to render Markdown as PNG, JPG, or PDF from any Zap. Any trigger app works — the rendering is a single POST step.

Why

What people build with it

Post a rendered card to Slack or Discord whenever a new item lands in Airtable, Notion, or a form.

Convert a Markdown newsletter draft into a PDF and email it to reviewers automatically.

Render AI-written Markdown into an image before it reaches a social scheduling app.

Setup

Connecting Zapier

01
Create an API token under Profile → API tokens. It starts with mti_ and is shown only once.
02
Add an action step and choose Webhooks by Zapier → Custom Request.
03
Set the method to POST and the URL to the generate endpoint. Under Headers add Authorization with the value Bearer followed by your token, and Content-Type set to application/json.
```
POST https://markdowntoimage.com/api/v1/images/generate
```
04
Put this in the Data field. Replace the placeholder with the field from your trigger that holds Markdown.
```
{
  "markdown": "{{content}}",
  "format": "png",
  "width": 800
}
```
05
Zapier parses the JSON response automatically, so data imageUrl is selectable in any later step.

Every parameter — themes, fonts, code styles, page size for PDF — is listed in the API reference.

Troubleshooting

Support

Which Zapier plan do I need?

Webhooks by Zapier is a premium built-in app, so it requires a paid Zapier plan. There is nothing to install on our side beyond the token.

Should I use Custom Request or POST?

Custom Request gives you explicit control over headers, which is what the bearer token needs. The plain POST action can work too, but Custom Request is less fiddly to get right.

Can I use it in a multi-step Zap with AI?

Yes. A common pattern is an AI step that writes Markdown, then this step renders it, then a publish step posts the image. The image URL is available to every step after the webhook.

What if the Markdown contains quotes or newlines?

Insert the field through Zapier's field picker rather than typing it into the JSON by hand — Zapier escapes the value for you. Hand-written JSON is where most formatting errors come from.
