Mercari temporarily blocked
ListSwiftly connects to Mercari by signing in as you, the same way you would in a browser — Mercari doesn’t publish a seller API. Because of that, Mercari’s own network protections can occasionally get in the way of a sync, separately from anything being wrong with your account.
What this looks like
Section titled “What this looks like”A sync that’s affected shows a message along these lines: Mercari’s network blocked the request rather than answering it, your sign-in itself is fine, and ListSwiftly will retry automatically. In ListSwiftly’s own wording, this usually clears on its own within the hour.
This is different from your session expiring — if it’s expired, ListSwiftly tells you to reconnect instead. A temporary block doesn’t need that; the retry that’s already scheduled handles it.
What to do
Section titled “What to do”- Nothing, for a first occurrence — let the next automatic sync try again.
- If it keeps happening well past an hour, or every sync to Mercari fails the same way, contact support.
Signing in specifically
Section titled “Signing in specifically”If you’re in the middle of connecting or reconnecting Mercari and it shows a CAPTCHA/verification challenge on Mercari’s own sign-in page, that’s a different moment from the block above: ListSwiftly does not attempt to solve a CAPTCHA on your behalf, and asks you to try signing in again. If it keeps happening, try again after a while, and make sure the account credentials you entered are current.
