Folder from vtigersync_3.zip should be placed in prestashop root directory

• vtigersyncconfigconfig.php

here connection with vtiger - ​link, access token and sync time interval

• vtigersyncconfigmapfields.php

here field mapping - vtiger field vs prestashop fields

• vtigersynccronvtigersync.sh

this file should be added in cron

You need to create table in Prestashop database and insert data inside

CREATE TABLE IF NOT EXISTS `vtigersync` (

  `id` int(11) NOT NULL,

  `time` datetime NOT NULL,

  `actual_order` datetime NOT NULL,

  `actual_contact` datetime NOT NULL,

  `actual_product` datetime NOT NULL,

  `next_order` datetime NOT NULL,

  `next_contact` datetime NOT NULL,

  `next_product` datetime NOT NULL,

  PRIMARY KEY (`id`)

) ENGINE=MyISAM;

INSERT INTO `vtigersync` (`id`, `time`, `actual_order`, `actual_contact`, `actual_product`, `next_order`, `next_contact`, `next_product`) VALUES

(1, '2017-01-31 09:00:02', '2017-01-31 09:00:02', '2017-01-31 09:00:02', '2017-01-31 08:45:01', '2017-01-31 09:15:02', '2017-01-31 09:15:02', '2017-01-31 10:45:03');

Its nessesary to create field in vtiger Product profile where will be placed prestashop_product_id

vtigersyncvtigerconnector.php

line 282 - need to place fieldname of prestashop_product_id that created in vtiger

$queryResult = $this->client->doQuery("SELECT * FROM Products WHERE cf_753<-!!HERE!! = '$sku';");
