Clay

Clay does not let other apps read your tables, so Echo works the other way round: an HTTP API column in Clay sends each row to Echo. The rows then appear in the Import leads dialog under Clay, grouped by list name.

#1. Create a token

In Settings, Integrations, on the Clay card, click Create Clay token. Copy it: it is shown once. You can have up to 10 tokens and revoke any of them.

#2. Add an HTTP API column in Clay

{
  "list": "Q4 RevOps leaders",
  "row": {
    "first_name": "{{First Name}}",
    "company": "{{Company}}",
    "title": "{{Title}}",
    "email": "{{Email}}",
    "website": "{{Website}}"
  }
}

list is the name the rows are grouped under in Echo. Send only the columns your page needs.

#3. Import into Echo

Open Leads, Groups, Import leads, choose Clay, pick the list, tick the fields and import.

#Rules

• Rows with the same email in the same list update the existing row instead of duplicating it.
• Up to 500 rows per request (send "rows": [...] instead of "row"), 500 KB per request, and 600 requests a minute.
• Clay's own limit: a webhook source table accepts 50,000 rows over its lifetime.

#Getting links back into Clay

Download the campaign CSV and import it into Clay, matching on email; the space_url column holds each lead's link. Or let Clay's own sequencer action use the link column.
