Unable to subscribe to notifications (REST API)

Trying to call the `notification/settings` endpoint (POST) with the following payload:

```
[notificationType] => Curl_Seller_Item_Close_Sold
[destination] => <...>/delcampeAPI.php
```

returns the following unexpected response:

```
[Delcampe_Notification] => Array
(
[Notification_Token] =>
[Notification_Datetime] => 2018-05-22 11:26:00
[Notification_Data] => Array
(
[Headers] => Array
(
[Ressource] => item
[Action] => POST
[Status] => 400
)

[body] => Array
(
[error] => Array
(
[0] => The asked destination ("<...>/delcampeAPI.php") seems to be invalid!
[1] => The asked notification type (Sold_Close_Item) is not valid! Call getAvailableNotitications to receive a list of valid notifications type...
[2] => Cette valeur n'est pas valide.
)

)

)

)

)
```

Both, `Curl_Seller_Item_Close_Sold` and the destination should be valid values. Why is this failing?

Hey benjaminl,

We're trying to create a new notification subscription: Link (https)

We're pretty sure that we're making the right calls.
This has been working forever, w're using the same file we've used in the past to do this.

We're executing a POST call on the ` Link (http) ` endpoint, with sending the following post fields:

$postData = array(
'notificationType' => 'Curl_Seller_Item_Close_Sold',
'destination' => '<...>/delcampeAPI.php'
);

I just tried this again, this time with a different Delcampe account that we take care of and we get the same error.
I think the REST API endpoint to add a new notification might be misconfigured on your end.

Also, the error message saying `Call getAvailableNotitications to receive a list of valid notifications type` is weird.
There is no `getAvailableNotifications` call on the REST API. That's the SOAP API.

#0 The URL is valid. Of course I have redacted it from my message before posting to this forum.

I just tried testing this with a different Delcampe account again, one where we have notifications setup and working. It tells me that my URL is invalid, even though for that exact same URL there are other notification subscriptions already existing!

Is there any way I can send you a private message, so I can send you the full cURL command I'm running?



#1 That's the problem! I'm sending in `Seller_Sold_Close_Item`, but it's saying that `Sold_Close_Item` is not valid. It doesn't make any sense.
I tried to change the `notificationType` I send to be `Curl_Seller_Sold_Close_Item` instead, and now I get this error:

<error>The asked notification type (SoldItem) is not valid! Call getAvailableNotitications to receive a list of valid notifications type...</error>

Then I changed the `notificationType` I send to `SoldItem`, and voila, it seems to work. At least I'm not seeing any further errors for an invalid `notificationType` anymore now. Given that `SoldItem` is the new correct value, I think your documentation needs to be updated.



However, I'm still unable to make the request go through because of #0.

I also got this error...

notificationType: Curl_Seller_Item_Add
destination: Link (https)

and got:

<error>The asked destination (" Link (https) seems to be invalid!</error>
<error>The asked notification type (StartedSale) is not valid! Call getAvailableNotitications to receive a list of valid notifications type...</error>
<error>Cette valeur n'est pas valide.</error>

What's wrong?

@vaccarisrl Thanks a lot for chiming in!

Cool, just two clarifications one more time.
1. It doesn't matter which user you try this with. It happens for all of them.
2. It doesn't matter which URL you provide for the "destination" input. It says they are all invalid. In my examples below I used " Link (https) ".

In my case these are the requests and the responses I got. The Delcampe user is "rolfschwerdt".

curl --request POST \
--url ' Link (http) ;' \
--form notificationType=Seller_Item_Close_Sold \
--form destination=<MY_URL>

<error>The asked destination (" Link (https) seems to be invalid!</error>
<error>The asked notification type (SoldItem) is not valid! Call getAvailableNotitications to receive a list of valid notifications type...</error>
<error>Cette valeur n'est pas valide.</error>


Now, after changing the `notificationType` to "SoldItem" I still get this:

curl --request POST \
--url ' Link (http) ;' \
--form notificationType=SoldItem \
--form destination=<MY_URL>

<error>The asked destination (" Link (https) seems to be invalid!</error>
<error>Cette valeur n'est pas valide.</error>

Awesome! Thanks for letting us know!

I'll be happy to forward this to our clients and let them know that they can use our Delcampe integration soon.

Thanks for getting back to us.

However, we're still experiencing the exact same error messages.
I have tried both `notificationTypes` values, "Seller_Item_Close_Sold" (which is documented in Link (https) which gave me the same error again:

[0] => The asked destination ("<...>/delcampeAPI.php") seems to be invalid!
[1] => The asked notification type (Sold_Close_Item) is not valid! Call getAvailableNotitications to receive a list of valid notifications type...
[2] => Cette valeur n'est pas valide.


After that we tried "SoldItem" which still made these two errors show up:

[0] => The asked destination ("<...>/delcampeAPI.php") seems to be invalid!
[1] => Cette valeur n'est pas valide.

It's working again, exactly like it used to before!
Just like you said, my mistake earlier today was to leave out the "Curl_" at the beginning.

Thanks for fixing this before the weekend! Much appreciated.
