Seller API: Keys, Limits and Webhooks

Create keys in Account, API Keys. You can have up to 5 active keys, so you can rotate one without downtime. Keys can be read or write. Sell Now access is granted by Misprint on request.

Each key can make 100 requests per minute. Go over that and requests are turned away until the minute resets. Your tool should wait the time we ask for and try again.

We can notify your server when:

• an order is created
• tracking changes
• an order is delivered
• a refund is requested or processed
• a buyer leaves a review

Your server should reply with a success response promptly. If we do not hear back, we retry several times over about 15 hours. Each delivery is signed so you can confirm it came from us, and carries a unique ID so you can ignore duplicates.

Sell Now access is granted by Misprint on request. If a Sell Now request comes back unclear, check your orders before retrying, because the sale may have gone through. Sell Now is unavailable until a new seller’s first sale ships.
