I’m calling this RESTAPI URL: Shipment/ConfirmShipment

Using a body:

{"entity":{"Type":{"value":"Shipment"},"ShipmentNbr":{"value":"SH00788384"}},"parameters":{}}

 

Question: how long do I need to wait between calls to this URL?

 

I get an empty response back when successful but if I don’t wait at least 5 seconds before I call the next Shipment/ConfirmShipment RESTAPI URL, I get this response:

When you invoke an action through the REST Api, you’ll get back a Location link that you can query to see when the process has completed.

From the I330 documentation:

Monitor the status of the release operation by using a request with the following settings:
• HTTP method: GET
• URL: https://localhost/MyStoreInstance/entity/Default/20.200.001/SalesInvoice/ReleaseSalesInvoice/
status/389fbc0c-7fc1-42f9-a2d2-822e15959f15 (You copy this URL from the Location header of the
previous POST request.)
• The headers shown below

  • Key Value
  • Accept application/json

Content-Type application/json
Once the GET HTTP method returns 204 No Content, the operation is completed

This is correct. refer to documentation @ Execute an Action That Is Present in an Endpoint

I’m doing a POST and there is no URL is being returned.  Just an empty response if successful and a JSON object if there is an error.  Are you saying that I also need to call a monitoring URL constantly to find out when the operation is completed?  If so, how to I get this URL?

Are you getting a 202 or a 204 returned?  If you get a 204, then the operation is complete. If you’re receiving a 202, then you should have a Location header returned with the URL. Note that the Location is returned as Header value and not a Body value.

And, yes, when you get a 202, you do want to check that URL periodically until it, too, returns 204. How long that period is up to you but somewhere between 2-5 seconds should be fine.

I wrote a new helper method to do this Location URL checking.  Thank you for all your help!  Works fine now!  😀
