To create a YeezySupply task you MUST use the product SKU.
For YeezySupply, you can find the product SKU on your own by first navigating to the product and copying the SKU from the search bar.
The product SKU in this case would be FV6125.
Then, paste the SKU into the SKU field, choose a size and quantity, select a profile, and toggle any of the different modes (see below the following picture) depending on the release. If you want to use multisizing simply offset sizes by a comma 4,4.5,5. Select task specific proxy if you want, but it is not recommended unless you absolutely it because it's tedious and designed for smaller amounts of tasks. Below is a proper task setup for the above product.
See "How to import/export tasks (CSV and json)" for a detailed description on how to import your CSV sheet of task(s) into Phantom, or export your tasks from Phantom.
Enter your product SKU or URL into the URL column. Choose YeezySupply in the Site column using the dropdown. Choose a Size using the size dropdown. Enter proxies into the Proxy column if need be, this column can be left blank as it will use the proxies are saved in settings within Phantom. If you do fill out the proxy column, you must still save your proxies in settings, but proxies will be set to specific tasks if entered in the CSV. Enter a Profile in the Profile column, enter true or false for randomEmail, but it doesn't really matter as Phantom will randomize your email regardless (see how to do so here), enter true or false for randomName, enter true or false for oneCheckoutPerProfile, any other columns in the CSV can be left as is/default.
YeezySupply requires that you login in via Captcha Manager found in the View Tasks Page (see how to do so here). This will allow you to pass splash by harvest Recaptcha V3 Tokens.
Residential and Datacenter proxies work on YeezySupply, and both have had success.
We recommend around 5000 ms retry/error delay, but it is contingent on how fast you want your tasks to retry when they hit an error.
We recommend going at least 1:1 in terms of tasks to proxies, as YeezySupply does ban. We recommend randomizing your address, they are often times flexible on the numbers of pairs you can purchase per card, but you can use the same card across multiple items. We recommend you start when waiting room opens/sale starts (watch the message at the top of the waiting room and see if it changes to include "Sale has started" or wait for a notification from us).
