Notion Setup

Mirror WordPress form submissions into a Notion database with SheetLink Forms. Free, no add-on required - each submission becomes a database page.

Overview

The Notion destination mirrors each form submission into a Notion database, per sync rule, alongside your primary destination - every submission becomes a new page (row). It is free and built into the core plugin - no add-on required. Delivery goes straight from your WordPress server to the Notion API and runs after the primary delivery, on the same retry pipeline as the core sheet write.

You need two things from Notion: an internal integration token and the database ID.

Step 1: Create an internal integration

  1. Open notion.so/my-integrations and click New integration
  2. Give it a name (e.g. "SheetLink Forms") and select the workspace that holds your database
  3. Copy the Internal Integration Secret - this is the token SheetLink needs

Step 2: Share the database with the integration

  1. Open the target database as a full page in Notion
  2. Click the ... menu (top right) -> Connections -> add your integration
  3. Copy the database ID from the URL: notion.so/workspace/32-character-id?v=... - the 32-character string before ?v=

This sharing step is the one everyone misses. An integration can only see databases explicitly connected to it - a correct token with an unshared database returns a 404.

  1. In WordPress go to SheetLink -> Destinations -> Notion
  2. Pick the sync rule to mirror and check Enabled
  3. Paste the integration token and database ID
  4. Map form fields to your database's property names. SheetLink writes native Notion property types - Email, Phone, URL, Number, Select, Date, and Checkbox properties are detected from the database schema and filled with correctly typed values, not plain text
  5. Save, then Test - a page should appear in the database within seconds

Troubleshooting

  • 401: the integration token is wrong or was revoked
  • 404: almost always the sharing step - connect the integration to the database (Step 2), or the database ID is wrong
  • 400 validation errors: a mapped property name does not exist in the database, or its type cannot accept the value (e.g. text into a Number property)
  • Mirror deliveries appear in the Delivery Log and retry automatically on transient failures

Frequently asked questions

Why does a Notion request return 404?

Almost always because the database has not been shared with the integration. Open the database as a full page, use the ... menu, choose Connections and add your integration. A wrong database ID produces the same 404, so check the 32-character ID copied from the URL as well.

Is the Notion destination free?

Yes. Mirroring submissions into a Notion database is built into the free core plugin and needs no add-on. Using Notion as a rule's sole destination, with no Google Sheet, requires the SheetLink Plus, which includes Primary Destinations.

Which Notion property types does SheetLink write?

Email, Phone, URL, Number, Select, Date and Checkbox properties are detected from the database schema and filled with correctly typed values; other properties receive plain text. A 400 validation error means a mapped property name does not exist in the database or cannot accept the value, for example text into a Number property.

Does a failed Notion delivery retry?

Transient failures retry automatically on the same pipeline as the core sheet write, and every attempt is listed in the Delivery Log. A 401 (bad or revoked token), 404 (unshared database) or 400 (property mismatch) needs a configuration fix before it can succeed.
