In order to access orders information within MyCustomizer Rest API, you must generate an API key. The key should be used as by JWT specification.
We use pagination to allow you to fetch orders or designs. To fetch the first result, do not include or set lastIndex parameter to 0. To fetch the subsequent results, use the lastIndex number from your previous request, in the pagination section. You will reach the last result page when the collectionSize is equal as the lastIndex, or when the resultSize is 0.
