Send `meta.nextCursor` back as `before` to read the next page; a null cursor means the timeline is exhausted. `meta.retentionDays` is how long tracking events are kept, so anything older is simply not there. A contact id that does not resolve within the organization yields a 404. Requires the `contacts:read` scope. ## OpenAPI ````yaml /api-reference/openapi.json get /api/v1/user/contacts/{id}/activity openapi: 3.0.0 info: title: Brudcast API version: 1.0.0 servers: - url: https://core-service.prod.brudcast.com description: Production security: [] tags: - name: Analytics x-displayName: Analytics - name: Campaigns x-displayName: Campaigns - name: Contacts x-displayName: Contacts - name: Mailboxes x-displayName: Mailboxes - name: Messages x-displayName: Messages - name: Sender Identities x-displayName: Sender Identities - name: Sending Domains x-displayName: Sending Domains - name: Templates x-displayName: Templates - name: Webhooks x-displayName: Webhooks paths: /api/v1/user/contacts/{id}/activity: get: tags: - Contacts summary: List a contact's activity description: >- Returns the campaigns that targeted the contact and the delivery, engagement and unsubscribe events recorded against them, newest first.
