Campaigns

Manage campaign contacts

Creates, updates, or removes contacts in a campaign.

Usage scenarios

Upsert contacts (default): Contacts will be added if they don’t exist, or updated if they do. Contacts with a disqualified or completed status will not be added. If no action is specified, the API defaults to upsert.
Update existing contacts only: Set action to "updateOnly". Only contacts already in the campaign will be updated. Contacts not in the campaign are ignored. This is useful when your process might include contacts that aren’t in the campaign and you don’t want them added.
Remove contacts: Set action to "remove" and provide at least email or phone for each contact to remove.

External IDs (CRM routing)

Configure in Manage Assistants — Define external IDs per assistant so each one can reference CRMs outside Replify (for example HubSpot account IDs, storefront codes, or internal site codes).
Example — A key like hubspotId paired with values that distinguish Site A from Site B.
In this API — For organization-wide / multi-assistant campaigns, include optional externalIdKey and externalIdValue. Key names must match what you saved in Manage Assistants.
Where to put them — You can set externalIdKey / externalIdValue on individual contacts, at the request root, or both. See the schemas for those properties in this spec.

Key fields

action: Controls how contacts are processed. Options are "upsert" (default), "updateOnly", and "remove". This applies to all contacts in the request.
status: Use completed or disqualified to stop further outreach from campaigns. Other status values are allowed but won’t affect campaign behavior.
contactMetadata: Add any key:value pairs to inform your AI assistant’s behavior. For example, if you set "tier": "pro", you can configure your AI to identify and handle pro-tier contacts appropriately.
externalIdKey / externalIdValue: Optional; supported on request root and/or per-contact as described in schema field docs.
