Map Custom Lead Fields to Your CRM
Want to sync not just the default lead details (like name, contact details, job info) but also your custom fields from Spreadly to your CRM? No problem! In this guide, we'll show you step by step how to map custom lead fields, including how to grab the right API key from your CRM system (specifically for HubSpot and Pipedrive).
1. Create or Edit a Custom Lead Field in Spreadly
First, head to the Custom Attributes section in your Spreadly dashboard.

When creating or editing your custom attribute, you'll see a CRM field input. This is where you'll paste the CRM field's API key (sometimes called "internal name" or "field key").

2. How to Find the API Key for Your CRM Field
HubSpot
Follow these steps to get the internal name (API key) of your HubSpot property:
- Open a Contact and Click "Actions" → "View all properties"

- Search or Browse for Your Property, Then Click "Manage properties"

- Find the Property and Click It

- Copy the "Internal name". That's your API key!

Pipedrive
- Go to "Data fields" in Your Company Settings

- Find Your Custom Field, Click the Three Dots, and Select "Copy API key"

3. Paste the API Key into Spreadly
Head back to the custom field in Spreadly and paste the copied API key into the CRM field input.
That's it! Your custom Spreadly field will now sync directly with your CRM's custom property.
