How to link a contact and a deal in amoCRM?

Question

API

I use the documentation
https://developers.amocrm.ru/rest_api/leads_set.php
https://developers.amocrm.ru/rest_api/contacts_lin... (I don’t understand how to implement it)
Now I have: when sending from the site, a Contact is automatically created , Task and Deal. The Task is associated with a Contact, but the Deal is not associated with a Contact. How to link the latter?
**** 'element_id' => $contact_id - associates a task with a contact; for the transaction, this option does not work.

Answer 1

We first create a deal and then we create a contact.
It turns out that we link transactions to a contact, and not vice versa.
linked_leads_id - list with IDs of the contact's deals
https://developers.amocrm.ru/rest_api/contacts_set.php

Answer 2

If you do everything as in the manual, but the linking does not work, try adding (int) to the 'linked_leads_id' parameter before the value, in the file contact_add.php

Answer 3

I needed to create deals and link to an existing company, I took a request from the admin panel:

POST /ajax/leads/multiple/add/
ACTION: ADD_DEAL_FROM_CONTACTS
new_deal[0][name]: Название сделки
new_deal[0][status]: ID статуса сделки
new_deal[0][pipeline_id]: ID воронки
new_deal[0][main_contact]: ID компании
new_deal[0][element_type]: 3
new_deal[0][price]: Сумма сделки

The main thing is to add a title
