Streak CRM for Gmail API
Streak Gmail-native CRM REST API for sales, support, and operations teams to manage pipelines, contacts, and deals entirely within Gmail and Google Workspace with email tracking, mail merge, and workflow automation. Enables AI agents to manage pipeline and box (deal) creation for Gmail-native CRM automation, handle contact and organization management for relationship tracking automation, access email tracking and open/click detection for sales intelligence automation, retrieve mail merge campaign creation for personalized outreach automation, manage pipeline stage and field configuration for sales process automation, handle task and reminder creation for follow-up automation, access Google Workspace calendar and task integration for workflow automation, retrieve pipeline analytics and funnel reporting for sales performance automation, manage data import and export for CRM migration automation, and integrate Streak with Zapier, Slack, and productivity platforms for end-to-end Gmail-embedded sales workflow automation.

⚡ Reliability
Best When
A Gmail-centric SMB or startup team wanting AI agents to automate deal pipeline management, email tracking, mail merge campaigns, and contact management entirely within Google Workspace through Streak's Gmail-native CRM.
Avoid When
GMAIL DEPENDENCY CREATES SINGLE POINT OF FAILURE: Streak is fundamentally a Gmail-based product; any Gmail or Google Workspace outage affects all Streak functionality; automated CRM workflows with high availability requirements must consider Gmail uptime SLA as part of Streak availability; Google Workspace service incidents propagate to Streak pipeline access. PIPELINE DATA IN GMAIL THREAD CONTEXT — NOT PORTABLE: Streak pipeline boxes are linked to Gmail threads; automated CRM data export for BI or backup must handle Streak's Gmail-thread-linked data model; automated analytics on Streak pipeline data requires transformation from Gmail-thread-centric model to standard CRM object model. EMAIL TRACKING PIXEL DETECTION BY MAIL CLIENTS: Streak email open tracking uses standard pixel tracking; modern email clients (Apple Mail Privacy Protection, corporate proxy tracking protection) block tracking pixels creating false zero-open rate; automated sales intelligence based on Streak email open data in environments with privacy protection creates misleading outreach timing.
Use Cases
- • Managing deals from Gmail-native pipeline agents
- • Tracking email opens from sales intelligence agents
- • Running mail merges from outreach automation agents
- • Tracking hiring pipelines from Gmail-based HR agents
Not For
- • Standalone CRM without Gmail dependency (use HubSpot, Salesforce, or Pipedrive)
- • Enterprise CRM with complex automation (Streak is SMB/startup-focused)
- • Non-Google Workspace organizations

Agent Metadata
Known Gotchas
- ⚠ BOX vs THREAD vs CONTACT OBJECT MODEL: Streak uses Box (deal record), Thread (email conversation), and Contact as core objects; automated CRM operations must understand relationship between objects; automated box creation without thread linkage creates orphaned pipeline records not visible in Gmail thread context; proper workflow: create box → link thread to box → add contacts
- ⚠ PIPELINE-SPECIFIC CUSTOM FIELDS NOT SHARED: Streak custom fields are pipeline-scoped and not shared across pipelines; automated multi-pipeline workflows must maintain separate field mapping per pipeline; automated data extraction that assumes uniform field schema across pipelines encounters missing field errors for pipeline-specific field IDs
- ⚠ MAIL MERGE SENDING VIA GMAIL RATE LIMITS: Streak mail merge sends via Gmail; Google Workspace enforces sending limits (500/day for consumer Gmail, 2000/day for Workspace); automated outreach via Streak mail merge must enforce sending limit; automated bulk outreach exceeding Gmail sending limits creates deferred/failed delivery without Streak-level error
- ⚠ WEBHOOK DELIVERY REQUIRES STREAK PRO+: Streak webhooks for pipeline events are restricted to Pro and Enterprise plans; automated event-driven workflows using Streak webhooks must verify plan supports webhooks; free/Solo plan automated workflows must use polling rather than webhooks for box stage change detection
- ⚠ GOOGLE OAUTH TOKEN REFRESH FOR LONG-RUNNING AUTOMATION: Streak API OAuth tokens require refresh after expiry; long-running automated pipelines must implement token refresh before expiry; automated CRM workflows that assume static OAuth tokens create authentication failures after 60 days without refresh
