What words can I use besides 'sold'

Any of these keywords will trigger the autoresponse: buy, sold, claim, and mine

So for example, commenting "sold 101" or "buy 101" will trigger the chatbot to sell the product tagged 101 to the person who commented

Your shoppers can also comment with the variant in the comment itself. So for example "mine 101 XL" will work and will skip the question about size.

Unless you are using custom tags (only available for Retail and Scale plans), your shoppers do NOT need to include the word 'sold'. They can just comment with the tag like "101". You can try it by commenting "101" on this test post
