First download the module from link. Next, unpack the archive and move the module files from the "Upload" folder to the root directory of the site.
In the administrative settings, open the "Modules/Extensions" section. In the list that opens, find the "RetailCRM" module and click on the "Activate" button.
After activating the module, access to editing will open.
On the edit page, specify the API version used, the system address (for example, https://demo.retailcrm.pro), and the API key created earlier.
Next, select the countries for which shipping of products will be available (required to synchronise delivery methods).
The "Currency settings" field is intended to specify the currency in which the price will be uploaded in the ICML catalogue.
After entering all the necessary data, click on the "Save" button.
In the "References" tab, you must specify the correspondence between the values of the reference books of the online store and the system (RetailCRM).
In the "By default" section, you can configure the payment and delivery methods that will be specified in the order when exporting from the system, if they have not already been selected.
Check if the system has the necessary reference values corresponding to the reference books of the online store. You can add new values in the Data books section.
After saving the settings for matching data books, click on the "Upload customers and orders" button to upload existing orders and customers to the system.
If you want to immediately generate a catalogue to be uploaded to the system, click on the "Upload catalogue" button.
The product catalogue will be generated at http://yoursite.com/retailcrm.xml, (where 'yoursite.com' is the site address). The catalogue address must be inserted into the "URL of ICML file" field to synchronise the store catalogue with the system.
To automatically generate the catalogue, you need to add an entry to cron:
v3.x - * */4 * * * /usr/bin/php /path/to/opencart/system/cron/icml.php >>/path/to/opencart/system/storage/logs/cronjob_icml.log 2>&1
v4.x - * */4 * * * /usr/bin/php /path/to/opencart/system/library/retailcrm/cron/icml.php >>/path/to/opencart/system/storage/logs/cronjob_icml.log 2>&1
To get changes and new data from the system, add the following entry to cron:
v3.x - */5 * * * * /usr/bin/php /path/to/opencart/system/cron/history.php >>/path/to/opencart/system/storage/logs/cronjob_history.log 2>&1
v4.x - */5 * * * * /usr/bin/php /path/to/opencart/system/library/retailcrm/cron/history.php >>/path/to/opencart/system/storage/logs/cronjob_history.log 2>&1
To download promotion prices from the site, add the following entry to cron:
v3.x - 0 0 * * * /usr/bin/php /path/to/opencart/system/cron/prices.php >>/path/to/opencart/system/storage/logs/cronjob_prices.log 2>&1
v4.x - 0 0 * * * /usr/bin/php /path/to/opencart/system/library/retailcrm/cron/prices.php >>/path/to/opencart/system/storage/logs/cronjob_prices.log 2>&1
Note
After adding an entry to cron, set up the "Settings for exporting the promotion price" field, which will be located on the main tab of the administrative panel of OpenCart, where the mapping of the system's "Price type" databook is specified.
