# Close CRM
> Integrate Mavera with Close CRM — email sequence A/B validation, call recording analysis, lead-to-persona automation, and smart view content generation
## Overview
These jobs show how to **pull data from Close CRM** (Emails, Calls, Leads, Smart Views) → **analyze with Mavera** (Chat, Focus Group, Mave Agent, Generations) → **get persona-validated insights** for outbound strategy, call coaching, persona management, and content generation.
**Close API** uses a single base URL for all endpoints. Authenticate with an **API Key** via HTTP Basic Auth (key as username, empty password) or **OAuth 2.0** Bearer tokens.
| Detail | Value |
| ------------------- | ---------------------------------------------------------------- |
| **Base URL** | `https://api.close.com/api/v1/` |
| **Auth** | API Key (HTTP Basic — key as username) *or* OAuth 2.0 Bearer |
| **Rate limits** | 10 RPS (Starter) → 40 RPS (Enterprise); `X-Rate-Limit-*` headers |
| **Mavera surfaces** | Chat, Focus Group, Mave Agent, Generations |
***
## Prerequisites
Generate an API key from **Settings → API Keys** in Close.
Grab your key from [app.mavera.io/settings/api](https://app.mavera.io/settings/api).
```bash theme={"dark"}
export CLOSE_API_KEY="api_..."
export MAVERA_API_KEY="mvr_..."
```
```bash Python theme={"dark"}
pip install requests openai
```
```bash JavaScript theme={"dark"}
npm install openai
```

## Jobs
Show top and worst-performing cold emails to a Focus Group for qualitative A/B validation
Transcribe call recordings and feed them into Mave Agent for structured meeting analysis
Auto-create Mavera Custom Personas for each ICP segment based on Close lead data
Pull leads from Smart Views and auto-generate personalized outreach content
***
## Production Tips
Close uses `has_more` + `_skip` for pagination:
```python theme={"dark"}
all_leads = []
skip = 0
while True:
resp = close_get("/lead/", {"_limit": 100, "_skip": skip})
all_leads.extend(resp.get("data", []))
if not resp.get("has_more"):
break
skip += 100
```
Read `X-Rate-Limit-Reset` header on 429 responses and `time.sleep()` before retrying. Limit concurrent requests to stay under 10-40 RPS based on your plan tier.
Call recordings are immutable. Cache transcripts keyed by `activity_id` to avoid re-transcribing.
Use Close webhooks (**Settings → Webhooks**) to trigger lead-to-persona sync on lead create/update.
