FAQs

Where do I get my Reevo API key?
Go to Settings → Integrations → API Keys → Account & Contact Creation in Reevo and generate a new key. Can I send custom fields to Reevo?
Yes. You must first create the field in Reevo and copy the Field API name. Use it in the contact_custom_fields or account_custom_fieldsobject of the JSON body. Where do I get custom field API names?
To find your custom field’s API name, hover over the field on the custom field Settings page in Reevo. What happens if a contact already exists in Reevo?
Duplicate contacts (based on email) will not be created again. The webhook will reject the entry, and you’ll see a non-200 status code. Can I map different columns in Clay to Reevo fields?
Yes. Just modify the JSON body to pull in any value from your Clay table. What’s a common use case for custom fields?
Many users include a “Lead Source” or “List Name” so contacts can be filtered and grouped in Reevo for sequencing or dialing later.
