This error means Apollo deprecated the endpoint you're using. You need to update your HTTP API configuration to use the new endpoint they specified.
Apollo has multiple API keys for different endpoints, so make sure you're using the correct API key for the new endpoint.
Can you copy and paste your current JSON configuration so I can help you troubleshoot the specific setup?

Got it! Since you're using our native Apollo integration (not HTTP API), that deprecation error suggests there might be an issue with your Apollo API key or connection setup.
Try checking if your Apollo API key has the right permissions for the endpoint you're trying to use. Sometimes Apollo has different API keys for different endpoints.
If you're still seeing connection issues, you might need to verify your entire API key was copied correctly - even one missing character can cause verification errors.
What specific Apollo action are you trying to run when you get this error?

The deprecation error you're seeing is likely related to your Apollo API key permissions or configuration. Since you're using our native Apollo integration for "Find People By Job Title," try these steps:
First, refresh your browser (Cmd/Ctrl + Shift + R) and retry the affected rows using the error retry option.
If that doesn't work, check that your Apollo API key has the correct permissions for the people search endpoint - Apollo often has different API keys for different endpoints. Even one missing character when copying your API key can cause verification errors.

another error after checking the apis on apollo- Unexpected token ‘I’, “Invalid ac”... is not valid JSON

That "Invalid JSON" error means there's a formatting issue in your configuration. The "Unexpected token 'I'" suggests there might be hidden characters or syntax problems.
Can you copy and paste your current JSON configuration into the chat? I can help troubleshoot the specific formatting issue.
Common causes are missing quotes around string values, extra commas, or hidden characters copied from documentation.

no json, it looks like this

That "Missing authentication" error with "Invalid JSON" suggests your Apollo API key isn't properly configured or verified.
Try these steps:
1.
Refresh your browser (Cmd/Ctrl + Shift + R) and retry the affected rows
2.
Double-check that your entire Apollo API key was copied correctly - even one missing character causes verification errors
3.
Make sure you're using the correct API key for the people search endpoint
If that doesn't work, try using Sculptor (top-right corner) to help troubleshoot the Apollo connection setup. Let me know if Sculptor helps or if you're still seeing the authentication error!

for connecting clay to apollo, I didnt use api key, i used oauth as only that was available

Got it! If you used OAuth to connect Apollo (instead of an API key), the authentication error might be related to your OAuth connection needing to be refreshed or re-authorized.
Try going to Settings > Connections, find your Apollo OAuth connection, and see if there's an option to refresh or re-authenticate it. Sometimes OAuth tokens expire and need to be renewed.
If that doesn't work, you might need to remove the existing Apollo connection and add it again using + Add connection.
