Setup

Connect it in a few steps.

Set up with Zapier

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