# Heyreach API Guide for GTM Workflows

> Campaigns must be pre-created in HeyReach UI; resolve campaign IDs first, then batch inserts and confirm stats after writes.

## Playbook

Use HeyReach for outbound activation after qualification and verification are complete.

* Always list campaigns first and resolve the exact campaign target before inserts.
* HeyReach public API does not expose campaign creation. Do not attempt to create campaigns via API tools; create campaigns in HeyReach UI first, then reference the resulting `campaign_id`.
* Batch writes in small chunks and validate response shape before scaling.
* Pull campaign stats after insert operations to confirm downstream effects.

```bash theme={null}
deepline tools execute heyreach_list_campaigns --payload '{}'
```

```bash theme={null}
deepline tools execute heyreach_add_to_campaign --payload '{"campaign_id":"12345","contacts":[{"linkedin_url":"https://www.linkedin.com/in/example","first_name":"Ada","last_name":"Lovelace","email":"ada@example.com"}]}'
```
