software distribution

That's a business question, and it's really up to you how you want to handle distributors. If you have a more specific question about how to handle some technical issue then we'll be more than happy to help.

I only interested in technical implementation using LimeLM API.Does LimeLM support the case where the distributor website issues the product key?If my website issues the product key in response to a purchase originated from the distributor website, then how we implement this case?

Yes, you can either create another user account and give them direct access to your LimeLM account, or you can create your own web API that in turn uses the LimeLM web API to create the product keys. It's up to you.

Can we have the distributor website send API to create the product key without giving them direct access to LimeLM account? If not what access right is required for their website to automatically gen. pro. key?

Yes, you create your own API and/or web form that is hosted on your website. It doesn't have to be complicated. It would accept some "API key" from your distributor, and then in your script you would call the LimeLM API to return a key with any custom license fields set.

Thanks, but will this cause security problem? What is the procedure to ensure it is the distributor requesting the product key instead of from some hacker?

Well, you provide them with the unique "username / password" and/or API key to access the script on your servers, and then you validate that information. And presumably you take a cut of the profits of the keys they generate, so they have incentive to keep their access to your script secure.

Does that make sense?

Thank you, you have been very helpful.Is there example you can share to implement all this?Some links to learn the process and coding would be greatly appreciated.

Well, looking at the example web API code you can see the calls you'll need to make from the script to generate the product keys. As far as implementing an API key OR username/password system, using Google is your best bet. There are a billion ways to do it.
