Exploring basic rules

Let's try exploring the /lots endpoint:

.. literalinclude:: tutorial/lot-listing.http
   :language: javascript

Just invoking it reveals empty set.

Now let's attempt creating a lot:

.. literalinclude:: tutorial/lot-post-attempt.http
   :language: javascript

Error states that the only accepted Content-Type is application/json.

Let's satisfy the Content-type requirement:

.. literalinclude:: tutorial/lot-post-attempt-json.http
   :language: javascript

Error states that no data has been found in JSON body.

.. index:: Lot

Creating lot

Let's create lot with the minimal (only required) data set:

.. literalinclude:: tutorial/lot-post-2pc.http
   :language: javascript

.. literalinclude:: tutorial/lot-patch-2pc.http
   :language: javascript

.. literalinclude:: tutorial/lot-patch-2pc-verification.http
   :language: javascript

Success! Now we can see that new object was created. Response code is 201 and Location response header reports the location of the created object. The body of response reveals the information about the created lot: its internal id (that matches the Location segment), its official lotID and dateModified datestamp stating the moment in time when lot was last modified. Pay attention to the lotType. Note that lot is created with verification status.

Let's access the URL of the created object (the Location header of the response):

We can see the same response we got after creating lot.

.. literalinclude:: tutorial/initial-lot-listing.http
   :language: javascript

Let's see what listing of lots reveals us:

We do see the internal id of the lot (that can be used to construct full URL by prepending and its dateModified datestamp.

The previous lot contained only required fields. Let's try creating lot with more data (lot has status created):

.. literalinclude:: tutorial/create-second-lot.http
   :language: javascript

.. literalinclude:: tutorial/pending-second-lot.http
   :language: javascript

.. literalinclude:: tutorial/patch-lot-to-pending.dissolution.http
   :language: javascript

And again we have 201 Created response code, Location header and body with extra id, lotID, and dateModified properties.

Let's check what lot registry contains:

.. literalinclude:: tutorial/listing-with-some-lots.http
   :language: javascript

And indeed we have 2 lots now.

Assume that we have lot in active.salable status and we want to modify this lot. For such purposes recomposed status exists.

.. literalinclude:: tutorial/patch-lot-to-recomposed.http
   :language: javascript

After some checks have been done, lot status will be switched to pending automatically.

Modifying Lot

Let's update lot description:

.. literalinclude:: tutorial/patch-lot.http
   :language: javascript

We see the added properies have merged with existing lot data. Additionally, the dateModified property was updated to reflect the last modification datestamp.

Checking the listing again reflects the new modification date:

.. literalinclude:: tutorial/lot-listing-after-patch.http
   :language: javascript

Deleting Lot

Let's delete lot:

.. literalinclude:: tutorial/lot-delete.http
   :language: javascript

Integration with assets

Concierge operations

For lot to be formed, you need to specify some id of the assets to be included in that lot. If all of the assets are available, they will be attached to lot and status will be changed to active.salable:

.. literalinclude:: tutorial/concierge-patched-lot-to-active.salable.http
   :language: javascript

In case of at least one of the assets is unavailable (e.g. it has already been attached to another lot), status of the current one will be turned to pending:

.. literalinclude:: tutorial/concierge-patched-lot-to-pending.http
   :language: javascript

When bot finds that status of lot is pending.dissolution, it turns status of the assets being attached to that lot to pending. Status of the lot itself will become dissolved.

.. literalinclude:: tutorial/patch-lot-to-dissolved.http
   :language: javascript

When bot finds that status of lot is recomposed, it turns status of the assets being attached to that lot to pending. Status of the lot itself becomes pending as well.

.. literalinclude:: tutorial/patch-lot-to-pending-from-recomposed.http
   :language: javascript

When bot finds that status of lot is pending.sold, it turns status of the assets being attached to that lot to complete. Status of the lot itself turns to sold.

.. literalinclude:: tutorial/patch-lot-to-sold-from-pending.sold.http
   :language: javascript

Convoy operations

When lot is finally formed (active.salable) it can be used in the procedure within CDB. For this to be done, you need to specify lot id. By doing this, you will find the merchandisingObject field with the current lot id in the created procedure and id of the auction within which it is going to be sold. Status of the lot used will be automatically changed to active.awaiting in RDB. This indicates that Organizer is creating some auction with this lot within CDB, so it is currently unavailable for usage.

.. literalinclude:: tutorial/convoy-patched-lot-to-active.awaiting.http
   :language: javascript

When the procedure is successfully created, lot status will be changed to

.. literalinclude:: tutorial/
   :language: javascript

After lot has been sold in the auction, its status is turned to pending.sold within RDB:

.. literalinclude:: tutorial/convoy-patched-lot-to-pending.sold.http
   :language: javascript

In case of that lot has not been sold, its status will be changed to active.salable in RDB:

.. literalinclude:: tutorial/convoy-patched-lot-to-active.salable.http
   :language: javascript
