# Clear external dependencies

> Domains, integrations, labels and links — the launch work that waits on other people.

Step 7 of the [launch path](/docs/guides/launch/overview). Everything here depends on DNS propagation, a supplier, or someone else's system. None of it is difficult and all of it is slow, which is why it has its own step rather than sitting inside go-live.

Start these now so [Test your processes](/docs/guides/launch/test-end-to-end) can run against the real thing rather than a temporary address.

## Your store address

Add your domain under **Settings → Domains** and verify it. Decide which address is primary for search engines.

Adding and verifying the domain happens here. **Making it primary happens at [Go live](/docs/guides/launch/go-live)**, not now — that is the switch itself.

<Note>
  Until a dedicated guide lands: [Domains](/docs/settings/domains) and [Set up the online store](/docs/guides/sales-channels/set-up-the-online-store).
</Note>

**Done when:** your domain is added and verified, and you know which address will be primary.

## Integrations and API access

Anything that needs to talk to TWICE — an accounting system, a booking widget, your own site — needs an API key from **Settings → Integrations & API** and pointing at the right endpoint. Webhooks are configured in the same view.

Test each integration end to end before you launch, not on the day.

<Note>
  Until a dedicated guide lands: [Integrations and API](/docs/settings/integrations).
</Note>

**Done when:** every integration has a key, is pointed at TWICE, and has been tested with real data.

## Labels and barcodes

If you label stock, decide the code format and print a test sheet before you print thousands. Check that a scanner reads them at the counter, at the angle and distance staff will actually use.

<Note>
  Until a dedicated guide lands: [Stock codes and barcodes](/docs/guides/inventory/stock-codes-and-barcodes).
</Note>

**Done when:** a printed label scans reliably at the counter.

## Links you already published

If you are replacing an existing site or booking flow, list every place your old links appear — your own website, business and directory listings, social profiles, email signatures, paid ads, and QR codes on printed material and signage.

Assign each one to a named person. This is the item most often discovered after launch, by a customer.

**Done when:** every place your old links appear is listed and has an owner.
