Instantly API v2 is officially here!

A major update with more endpoints and more control.

What’s New in API V2?

The second version of our API comes with improvements:

  • API V2 doubles the number of available endpoints compared to V1, including some of the most requested ones:
    Create campaigns

    Connect email accounts through imap/smtp

    Create lead lists

    Add leads to lead lists

    Create inbox placement tests

    Get Inbox Placement Blacklist & SpamAssassin Reports

    Fetch Inbox Placement Tests Analytics

    Manage custom lead labels, and many others.

  • API Scopes enable granular control over API keys and their usage.

  • Create multiple API keys with different privileges.

  • Full adherence to REST API standards.

  • Follows strict naming rules for entities, fields (snake_case), etc.

API is now accessible on the Growth Outreach plan.

V1 Compatibility

While API V1 will remain available and maintained for now, it will be deprecated in 2025.

API v2 is not compatible with the first version.

To avoid disruptions, we encourage all users to migrate to API V2 as soon as possible.

You will need a new API key to use the API V2 endpoints.
Details on how to generate one are in the new documentation site.
