I try to create a Shopify application with koa. I use the koa-shopify-auth official package and the two methods shopifyAuth and verifyRequest to get a token with right scopes from the shop.
After getting fresh and validated token with right scope, I make a request on https://xxx.myshopify.com/admin/api/2019-04/shop.json which is a simple endpoint to get information about the shop using app.
Sometime I get the right answer from the API, but sometime I get an error:
{
"errors": "[API] API Access has been disabled"
}
The token is good because some shop works well, the token is not invalid for this shop because this is not the same error (Invalid API key etc.)
Do you know this error message and why I get it ?
