Relationship and validation

Yes,
Problem 1:
When you make the purchase inside the wp_lic_key_tbl table, the license is registered by order, but in that table it does not register the ID item of EDD, it only registers the code of the order but in text (not optimal), it should register the Order (ID only) and item ID to be able to relate.

Problem 2: Register in the meta_data also the ID download or item

So far nothing difficult, now let’s start with the validations

Problem 3: When the client installs the product (plugin / theme) I imagine that there will be a validation form created by the developer, so far everything is perfect, that form must have 2 fields.
1) Purchase email
2) License
Once the client enters these 2 fields, what would be the validation code to confirm that it is a correct license?

I found on one page (https://www.tipsandtricks-hq.com/software-license-manager-plugin-for-wordpress) a way to validate the license with the “software-license-manager” plugin but I am not sure because nowhere it enters the license and the person’s mail.

Could you provide a “wp_remote_get” code with which this validation is simple with you extension?

I wait for your soon response
