No. These are User-Agent strings — a technical asset plugged into the account manager. The delivery contains no login, password or cookie, and the format is labelled accordingly: «строка» (string).

Why does the price per string differ so much?

Because of packaging volume. Positions with a large minimum batch cost many times less per string than small ones, while the product itself is the same. Compare the price per string at the volume you need, not the position price; the minimum batch is stated in the card next to the price.

How does the Web variant differ from the API variant?

By the kind of request the string was selected for: Web variants (iPhone, Android) describe a mobile browser, the API variant describes app API requests. They are not interchangeable.

What does «IAM only» mean on the API position?

That the batch targets work inside InstAccountsManager. Every position in the category is already marked «for InstAccountsManager»; this mark narrows the use further.

User-Agent strings

The only catalogue position that is not an account. These are User-Agent strings — a technical asset that is plugged into the account manager.

What arrives in the delivery string

The format is literally called «строка» (string). There is no login, no password and no cookie here, and there cannot be: you receive a set of User-Agent strings, one per record. Every position in the category is marked «для InstAccountsManager» — the software they were selected for.

Positions differ by device type and by the kind of request:

Mark in the title	What it is
iPhone · Web	strings for mobile Safari on iPhone
Android · Web	strings for the Android mobile browser
API	strings for app API requests
API · IAM only	the same, but the batch targets InstAccountsManager only

Where it imports

The strings are plugged into InstAccountsManager next to an account so that requests look like they come from the matching device. The on-site converter is of no use for this category: there is nothing to parse, the fields are not laid out — it is one value per line.

Match the string type to the account type: an iPhone string for an account run as mobile rather than as a web session.
Web variants (iPhone, Android) and the API variant are not interchangeable: they describe different kinds of requests.
A position marked «IAM only» is intended for work inside InstAccountsManager specifically.

What to check within 30 minutes

The replacement window is 30 minutes from purchase, and what is checked here is the composition of the delivery: whether the stated number of strings arrived and whether they are of the type named in the card. The behaviour of the account you plug the string into has nothing to do with this product.

Compare the number of strings with the order volume.
Compare the type: iPhone, Android or API — it is stated in the position title.
If the delivery does not match the card — support bot @boomlysup_bot, order number and SKU.

Batch size and repeat purchase

This is the category to look at most carefully, precisely because of packaging volume. The same string costs differently depending on whether you take a small batch or a large one, and the gap here is wider than in the other catalogue sections. Compare the price per string at the volume you need rather than the position price — the card shows the minimum and the quantity step.

The practical conclusion: comparing positions in this category by list price is meaningless — compare the price per string at your volume. The SKU is permanent; use it for restock alerts in the shop bot or for repeat buying through the public API.
