Etsy limits how much an app can change in one Etsy shop each day. When your shop reaches that limit, Etsy pauses Shuttle's requests until the limit lifts, so the product, order or review in progress stops with this error. Etsy sets this limit, so Shuttle cannot raise it or get around it.
Why Etsy's daily limit gets reached
A large run of product transfers, product updates, order transfers or stored reviews can use up Etsy's daily limit. Shuttle does not set a number of products or reviews per day. The limit is Etsy's, and how far a run gets before reaching it depends on the products, orders and reviews in it.
How you know Etsy's daily limit has been reached
Shuttle shows a banner at the top of its pages while the limit is on:
You've hit Etsy's API call limit on Products, Orders, Reviews and Stock Syncer
Etsy's API call limit reached on the overview and the inventory pages, where stock updates to Etsy are paused too
On Products, Orders and Stock Syncer, the banner shows roughly how long until Etsy lifts the limit, counting down from when the limit started. That estimate assumes Etsy lifts the limit about 20 hours after it began.
If the estimated time has passed and Etsy still has the limit on, the banner on Products, Orders and Stock Syncer says instead that the limit will lift automatically. The banner on Reviews always says this. Every banner disappears once your shop can make changes on Etsy again.
When a transfer run stops at the limit, Shuttle also sends an email to your notifications address. You can change that address in Settings > Account > Alerts & Notifications, under Notifications email.
What to do while Etsy's daily limit is on
Wait for Etsy to lift the limit. Do not start new transfers or updates while the banner shows, because they stop at the same point.
Pick up where the run stopped
Once the banner has gone, continue the run that stopped:
For products, open Products. If the Last transfer didn't finish banner shows, click Continue, then click Continue last transfer.
For orders, open Orders. If the Last order run didn't finish banner shows, click Continue.
For reviews, open Reviews and click Continue last run on the banner about the last store run.
If the error showed on a single product, transfer or update that product again.
How to stay under Etsy's daily limit
Split very large transfers across several days, so that each day's run fits within the limit.
