MX Lookup API + Notion Integration

Why connect them

The MX Lookup API in Notion.

Notion is the all-in-one workspace for notes, docs, and databases. Connecting APIs to Notion enables automated documentation, dynamic databases, and self-updating knowledge bases. Build living documents that stay current without manual updates.

What you can build

Workflows worth wiring.

Automatically create documentation pages when new API endpoints are deployed

Build a competitor tracking database that updates with the latest company data

Create a reading list that enriches book entries with metadata from external APIs

Maintain an always-current list of domain registrations with expiry dates

Templates

Ready-made ideas.

New database item created Look up MX records → update properties

Add mail server info to domain entries

When a new domain is added to your Notion database, look up its MX records and set the exchange and priority properties from the mx array.

New database item created Look up MX records → set status if no records

Flag domains without MX records

Automatically flag Notion entries where the MX lookup returns an empty mx array, indicating the domain cannot receive email.

Setup

Connect it in a few steps.

Set up with Zapier

1
Set the trigger. Create a Zap with Notion as the trigger app and "New database item" as the event. Connect your account.
2
Add the API action. Add APIVerve as the action, select the MX Lookup API, and map your trigger data to the request.
3
Send it back. Add a second Notion action for "Create page" and map the returned fields (like domain) 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 Notion module set to "New database item". Authenticate your account.
2
Call the API. Add an HTTP module pointing at api.apiverve.com/v1/mxlookup 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 Notion module for "Create page". Map fields like data.domain 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 Notion trigger node for "New database item" and connect your credentials.
2
Add an HTTP Request node. Point it at api.apiverve.com/v1/mxlookup using Header Auth (x-api-key). Feed in the trigger data.
3
Map with expressions. Add a Notion node for "Create page" and reference the response with expressions such as {{ $json.data.domain }}.
4
Execute & activate. Execute manually to verify, then activate the workflow for production.
