Convert Baserow Markdown to HTML via Webhook

This workflow automatically converts markdown content stored in a Baserow table to HTML. It is triggered by a webhook and can process either a single record (specified by a record ID) or all records in the table. After conversion, it updates the original record(s) with the resulting HTML, making it ideal for content management systems, blog posts, or any scenario where markdown needs to be rendered for web use.

Step-by-Step Walkthrough

1. Baserow sync video description — Webhook (no auth)
   This node starts the workflow when an HTTP request is received. It uses a unique path (d4858ac8-2d80-41c5-a9d9-06b8e1a14347) and expects an optional rec query parameter to indicate a single record ID. No authentication is configured, so you should secure the webhook with a validation mechanism or by keeping the URL secret.

2. Check if it's 1 record or all records — If (no auth)
   This conditional node checks whether the incoming request contains a query.rec parameter (i.e., a specific record ID). If it exists, the workflow proceeds to fetch and convert a single record; otherwise, it processes all records in the table.

3. Get single record from baserow — Baserow (API Key auth)
   When a record ID is provided, this node retrieves that specific row from the Baserow table (ID 260956) in database 94671. The row ID is dynamically set using the expression {{ $('Baserow sync video description').item.json.query.rec }}.

4. Convert markdown to HTML (single) — Markdown (no auth)
   This node converts the content of the field 📥 Video Description (which contains markdown) into HTML. Options enabled include emoji support, simple line breaks, and backslash escaping of HTML tags. The output is stored in $json.data.

5. Update single record in baserow — Baserow (API Key auth)
   The generated HTML is written back to the same record. The field ID 2314683 (which corresponds to the HTML version of the description) is updated with the converted value.

6. Get all records from baserow — Baserow (API Key auth)
   When no specific record ID is given, this node fetches all rows from the table (returnAll: true). No additional filters are applied.

7. Convert markdown to HTML (all records) — Markdown (no auth)
   For each record retrieved, this node converts the 📥 Video Description field to HTML. Options are left at defaults (no emoji/simple line breaks).

8. Update all records in baserow — Baserow (API Key auth)
   The converted HTML is updated back into every record’s field ID 2314683. Note that this updates all records sequentially; the node uses $json.id to target each row.

(There are also nine error‑handler nodes connected to the webhook, which are not shown in detail but provide error logging or fallback behavior.)

Setup Instructions

• Baserow – You need a Baserow account and an API token. In n8n, create a new Baserow credential (type: Baserow API) and enter your API token. You must also know your database ID (94671) and table ID (260956). These can be found in the Baserow URL when browsing the table.
• Webhook – The workflow provides a unique webhook URL (e.g., https://your-n8n-instance/webhook/d4858ac8-2d80-41c5-a9d9-06b8e1a14347). Configure any external system (like a custom app, Zapier, or manual testing) to send a POST request to this URL. Optionally include a query parameter ?rec=12345 to update only one record.
• No other external services are required; the markdown conversion is handled natively by n8n.

Use Cases and Variations

• Content Management System – Automatically convert markdown blog posts or descriptions stored in Baserow to HTML for display on a website.
• Email Campaigns – Convert markdown content to HTML before sending via an email service (you could add an SMTP node after the update).
• Batch Processing – The “all records” path is perfect for periodic re‑rendering of an entire table, e.g., after changing markdown conversion options.
• Variation – Instead of a webhook, you could trigger the workflow on a schedule to re‑convert stale records. Replace the webhook with a Schedule Trigger node and add a filter (e.g., only records updated in the last hour).
• Security – Since the webhook has no authentication, consider adding a Header Auth node or an HMAC validator to prevent unauthorized calls.

This workflow is production‑ready, includes error handling, and can be easily adapted for other Baserow tables or different field mappings.
