The "Could not generate OAuth code and state" error typically indicates an issue with your Apollo API key setup. Here's how to fix it: Check your API key: ** Verify the entire API key is copied exactly - even a single missing character can cause this error ** Ensure your API key has the necessary permissions and access to the enrich endpoint ** Confirm your API key is active and correct Additional troubleshooting: ** Try a browser refresh (Cmd/Ctrl + Shift + R) ** Check that you have enough credits in your Apollo account ** If the connection isn't visible, try adding a new connection by selecting "+ Add Connection" and choosing "Apollo" For proper API key setup guidance, reference Apollo's documentation.

Hey Nicole! Thanks for reaching out. Have seen this quite a lot in the last two three days. My team recommended you reach out to Apollo's support since we are not able to reproduce this on our end. That generally means its not an issue on Clay's end. Do reach out to them and let me know. Will keep an eye out for this issue!
