ShipHero GraphQL API Performance Testing

Hi! I am currently working on an integration with ShipHero for a high volume ecommerce fulfillment operation. The customer is expected to fulfill upwards of 6000 outbound orders per day.

Does anyone have experience fulfilling similar outbound order volumes (> 5000 orders/day) with ShipHero? Does ShipHero complete performance testing or does anyone know if this is within their limits?

For context, we are looking to perform the follow GraphQL mutations/queries on a regular basis to process the order data.

Create Orders Mutation: > 5000 orders/day
Query for shipped orders: > 5000 orders/day
Daily item syncs to update/create items > 300 items/day

Please let me know if anyone has experience with pushing this amount of volume through ShipHero. Happy to chat!
