API call limits will be applied to variant creation

We’re adding call limits that restrict the number of variants that can be created by the API after a shop reaches a certain threshold.

On March 14, 2019, we're adding new API call limits to the endpoints listed below. These limits will be rolled out over a period of a few weeks to the affected shops.

REST:

• POST admin/products.json
• PUT admin/products/{ID}.json
• POST admin/products/{ID}/variants/{ID}.json

GraphQL:

• productCreate
• productUpdate
• variantCreate

When an app reaches a limit, it will receive an HTTP 429 error. The app should then implement retry behavior.

For more information, see API call limits for specific endpoints.
