Inventory system management

To start with the integration of your inventory system you must start by registering your system on our platform. The generated id will be used by the others involved to communicate with your inventory system.

Webhooks

The POS can send different types of data about its inventory items, the inventory system that you have registered can receive this data by registering the urls of the webhooks where it wants to receive each of these types. Types of information that the POS sends:

• Type 1: Receive the POS item data list

• Type 2: Receive the stock updates of POS items

These webhook requests will send a header called X-Signature-Request, as a security measure to confirm that the request came from our system.

The value of this field is a hexadecimal HMAC signature of the next json payload, using the client secret as a key(generated on account creation) and SHA256 as the hash function.
