Progress Status
Progresses a box’s status to the next stage. This is only
available in test mode and can be used to simulate how a live order would
progress through the different statuses.
Note: this will fail with an invalid_progression_error if the status
is one of completed or cancelled.
Returns
This order will transition from ready to printing on the day after this date. For example, if this is a date on Tuesday, the order will transition to printing on Wednesday at midnight eastern time.
An optional string describing this resource. Will be visible in the API and the dashboard.
The last date that the IMB status was updated. See imbStatus for more details.
The most recent ZIP code of the USPS facility that the order has been processed through. Only populated when an imbStatus is present.
These will be merged with the variables in the template or HTML you create this order with. The keys in this object should match the variable names in the template exactly as they are case-sensitive. Note that these do not apply to PDFs uploaded with the order.
The tracking number of this order. Populated after an express/certified order has been processed for delivery.
PostGrid renders a PDF preview for all orders. This should be inspected to ensure that the order is correct before it is sent out because it shows what will be printed and mailed to the recipient. Once the PDF preview is generated, this field will be returned by all GET endpoints which produce this order.
This URL is a signed link to the PDF preview. It will expire after a short period of time. If you need to access this URL after it has expired, you can regenerate it by calling the GET endpoint again.
