Quick answers for developers connecting to **MJX CRM** in Pathshala. Each answer links to the page with the details.

## Keys and access

**Who can make an API key?**
The Owner or an Admin, on CRM › Setup › Advanced: API & webhooks. See [Authentication and API keys](developers/authentication-and-api-keys).

**I lost my key. Can I see it again?**
No — it is shown once. Revoke it and make a new one.

**Does a key work for more than one institute?**
No. A key belongs to one institute, and only that institute's leads can be reached with it.

**Can a key be limited to reading?**
Yes. Pick **Only read** when you make it. It cannot add or change anything, and an AI assistant using it sees only the read tools.

**What happens if the institute moves from Pro to Basic?**
Calls are refused with "The API comes with MJX CRM Pro." The keys are kept and work again on Pro.

## Leads

**What fields are required to add a lead?**
A phone number or an email. Send a name too. See [CRM API reference](developers/crm-api-reference).

**My form uses different field names. Do I have to rename them?**
No. `full_name`, `mobile`, `whatsapp`, `requirement` and many other spellings are recognised. Unknown fields are kept as Additional details.

**What does "duplicate": true mean?**
The phone (or, with no phone, the email) already belongs to a lead. Nothing was written; the existing lead is returned.

**Are foreign numbers accepted?**
Yes. A foreign number with its country code is kept as `+<digits>`.

**What are the statuses?**
`new`, `in_conversation`, `follow_up_due`, `converted`, `lost`. On screen they read New, Talking, Call back, Admitted / Joined / Won, and Not interested.

## Webhooks

**Which events are there?**
`lead.created` and `lead.status_changed` (with `previous_status`), plus `ping` from [[Send a test]]. See [Lead webhooks](developers/lead-webhook).

**Can my webhook be on http:// or a local address?**
No. It must be `https://` on port 443 and on the public internet.

**What if my server is down?**
We retry once after a minute. After 20 failures in a row the webhook turns itself off until you press [[Turn on again]].

## Lead sources and connectors

**What is the difference between a lead source and the API?**
A lead source is a one-way address for sending leads in, with no key, safe for a browser. The API needs a key and can also read and update.

**How do I connect Facebook lead ads?**
Press [[Connect Facebook]] on the Facebook & Instagram card. See [Lead connectors setup](developers/lead-connectors-setup).

**Can I put the form on WordPress or Wix?**
Yes. See [Embed the web form](developers/web-form-embed).

## MCP

**Which AI assistants can connect?**
Claude Desktop, Claude Code, Cursor, the Claude API's MCP connector, and any MCP client that can send an Authorization header. See [MCP server](developers/mcp-server).

**Can an assistant message my leads?**
No. MCP tools never send messages and cannot delete.

## Limits

**What is the rate limit?**
120 requests a minute per key (REST and MCP together). See [Rate limits and errors](developers/rate-limits-and-errors).

## Support

WhatsApp or call **7996837555**, or email **info@mjxtechnologies.com**.

## Questions people ask

### Where do I find my API base address?

On the Integrations page under For your developer — "Base address". It is your institute's own address followed by /api/v1/crm.

### Do I need CRM Pro for a website form?

No. The enquiry form, its embed code and a website lead source (Any form or tool) work on every plan. The API, webhooks, MCP and the IndiaMART, JustDial, Meta, LinkedIn, Google Ads and missed-call sources need Pro.

### Does a lead added through the API get a WhatsApp welcome?

No. Nothing added through the API, MCP or a lead source sends a message. Setting next_followup_at later lets the automatic follow-up message the person.

### Can I delete or assign leads through the API?

No. The API reads, adds and updates leads (status, tags, follow-up date) and adds notes.

### Is there an API for students, fees or attendance?

No. The public API covers MJX CRM leads only. The private app API (/api/app/v1) is not for other software.

### How do I test without a real lead?

Use your own number and delete the lead afterwards, or press "Send a test" on a webhook to get a ping with no lead in it.
