How can I generate discount coupons from my website via API?

Discount coupons can be either import-based (codes are manually uploaded) or API-based (codes are generated on-demand).

To generate discount coupons from your website via API, your website needs to provide a webhook URL that:

• Receives multiple GET parameters;
• Generates unique (single-use) codes on your website based on the provided parameters.

The mandatory GET parameters that can be specified are:

• type – INT – The type of discount generated by the coupon, which can be 0 (fixed value), 1 (percentage), or 2 (free shipping).
• value – INT | FLOAT – Appears for percentage or fixed value types. If type is 1 (percentage), it contains the discount percentage; otherwise, it contains the fixed value.

Optionally, the following parameters can also be specified:

• batch_size – INT – The number of codes that should be generated by the webhook URL (optional but recommended). Codes can be generated in batches to reduce the number of requests. A single code can still be returned even if this parameter is specified.
• prefix – STRING – The prefix that should be added at the beginning of the codes.
• expire_date – STRING – The expiration date in the format YYYY-MM-DD HH:MM for the codes.
• min_amount – FLOAT – The minimum cart value required to apply the coupon (if specified, it should be based on the amount without VAT).
• currency – STRING – Can be RON or EUR (used when specifying a fixed discount value or minimum order amount).

The returned response can be a string (containing the generated code if a single code was created) or an array (list of codes) in JSON format, containing the following keys:

• status – 0 (for error) or 1 (for success).
• codes – An array containing the generated codes (in case of success).
• msg – The error message (in case of error).
