Convert a lead into a contact, an account and optionally an opportunity.

SuiteCRM API: https://cotlet.dev/docs/api/suitecrm.md

`POST https://cotlet.dev/api/v1/suitecrm/leads/{lead_id}/convert`

Access: write. Confirm: waits for the user's OK before it runs.

Runs Convert Lead from the lead's Actions menu, with the sections pre-filled from the lead. If SuiteCRM shows a duplicate warning, nothing is created and the matching record is returned so you can pass its ID. The lead's Status becomes Converted, and several records are created, so this is not undone in one call. By default you confirm each call; you can switch that off for this tool.

## Parameters

| Name | Type | Required | Description |
|---|---|---|---|
| `lead_id` | string | yes | Lead ID from list_records. |
| `account_id` | string | no | Link to this existing Account instead of creating one. |
| `contact_id` | string | no | Link to this existing Contact instead of creating one. |
| `create_opportunity` | boolean | no | Also create an Opportunity. |
| `opportunity_name` | string | no | Name of the Opportunity. |
| `amount` | number | no | Expected value of the deal. |
| `close_date` | string | no | Expected close date, ISO date. Required by SuiteCRM when an opportunity is created. |
| `sales_stage` | string | no | Sales Stage, for example Prospecting or Qualification. |
