This is the workflow for how I integrate Apollo to add contacts for both Clay’s find people and Apollo’s find contacts for specified accounts, where I need greater coverage in case it’s helpful.
For other data providers with a Find contacts API you can use the same method to add more coverage.
When the account list is very large, I use Make to limit the new entries to the top of the workflow to 83 per hour via Google sheets to stop it running into Apollo API limitation issues
