How to properly handle subscriptions and their attached serialnumbers

Cees Meijer

Originally I just added devices throught the dashboard, which were then automatically added to a subscription (what I was not even aware of). Later, after ading a second endpoint, I found out that this second endpoint would only receive data after manually adding a subscription, which I did by using he Postman script:

{{base_url}}/m2m/subscriptions?type=resources

First I did this for a few single IMEI numbers, and then I also used it to register several numbers at once.
Later I noticed that everytime I do this, a new subscription, with it’s own ID gets created. So now when I ‘GET’ all subscriptions I get a long list with a all different subscription ID’s, and even some duplicate IMEI numbers with different ID’s.
Now I just found in the documentation that I can also add IMEI numbers to existing subscriptions, so that is probably a better thing to do for the next set of IMEI numbers.
But how do I even know which subscription belongs to what ? There obiously is one subscription that is used for the dashboard, but how do I know which one this is ? And how is it possible that all other subscriptions automatically go to the second endpoint ?

What is the easiest way to handle all this? The documentation just gives the CURL examples, and the existing Postman scripts make it a little easier, but I don’t think this very scalable once you have hundreds of devices.

Hi Cees,

The portal uses a different user to manage the subscriptions for all the devices in the project; so you will not see those subscriptions when using the API.
How you manage the subscriptions for your user is completely up to you, you can choose to add a new subscription for each device or you can reuse a subscription and add devices to it.

Multi endpoint capabilities are on the backlog/wishlist for the portal but we currently don’t have a date/sprint for it. If your use case requires this, please contact the iotcreators team to discuss this with them.

@Ederuiter But if I GET all Subscriptions, I do always get at least one subscriptionId section, with a list of IMEI numbers that match the numbers on the dashboard. And when I add something through the dashboard, it will also show up in this list. So what am I seeing then ?

Hi @Cees-Meijer ,

Yes you are right, I was thinking of the mysubscriptions endpoint:

{{base_url}}/m2m/mysubscriptions

This endpoint should only list the subscriptions associated with your user.

@Ederuiter Thanks. I did not know about ‘mysubscriptions’. But it seems indeed the easiest way to list only those.
