Yes, Clay uses Instantly's v2 API. If your integration is failing, here's how to resolve it: 1. Make sure you're using the correct API key:
โข Go to Instantly's "Integrations > Apps" section
โข Find the "Instantly API" app
โข Select "Copy API Key"Important: Do not generate your API key under "Integrations > API Keys" as that corresponds to an unsupported API version.Before using the integration, ensure you have: ** Added your Instantly API key to Clay
** Created a campaign in Instantly (note that campaigns cannot be created directly within Clay)You can add your Instantly API key within any Instantly enrichment panel in Clay.
