Detailed API documentation

The Swagger API documentation is always up-to-date and lets you try out any query with your user session or an API-key.

Integration guide

Fetching a case

Fetching a single case is simply done using the case ID

curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456

If successful, the above invocation will return the case basic model:

{
  "data": {
    "id": 123456,
    "subject": "My testcase",
    "description": "This is the description of the case",
    "customer": { "id":1, "shortName":"mnemonic", ...},
    "service": { "id":6, "shortName":"support", ...},
    "type":"operationalIncident",
    "status":"pendingCustomer",
    "priority":"medium",
    ...
  }
}

Creating a case

To create a case, you need to specify the service, case type, subject and description:

curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case -d '{
  "service": "support",
  "type": "operationalIncident",
  "subject": "My testcase",
  "description": "This is the description of the case"
}'

By default, the case is created for the customer bound to the current user. To specify a different customer, use the "customer" parameter. 

"customer":"mycustomer"  # ID or shortname of the customer to use

Note that the "service" parameter used must be valid for the selected customer. See Fetching subscriptions below to list which services are valid for a customer.

See Swagger API documentation for details on valid request parameters, and a detailed description of the returned data model.

Creating a restricted case

To create a case which is restricted from the time it is created, the create request can specify the accessMode variable, and optionally add users/groups with explicit access to the ACL members:

  "accessMode": "explicit",
  "aclMembers": [ { "subjectID":45, "level":"write" } ]

See Managing case access for details on access mode and ACL members.

Updating a case

Updating the basic fields of a case is done with a PUT request to the case resource.
If no parameters are provided, no changes are performed. Similarly, for any parameter to this endpoint, a null value will cause no change to the current value.

The example below will increase the priority to high, and change the status of the case to pendingSoc.

curl -X PUT -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/123456 -d '{
  "priority": "high",
  "status": "pendingSoc"
}'

See Swagger API documentation for details on valid request parameters.

Related endpoints

Other endpoints related to updating/modifying a case

• Adding a comment
• Adding an attachment
• Closing a case
• Moving the case to another service, case type and/or customer
• Managing case access
• Managing case tags

Restricted fields

Some fields only permitted to update by users which are granted the TECH role for the case:

• assignedTech
• reporter
• subject (can be changed by case owner)
• description (can be changed by case owner)

Attempts to update restricted fields will result in a 403 error code, with a FIELD_ERROR message explaining the error.

See Understanding case access for more details on access controls.

Update with comment

Adding a comment is a separate endpoint, but can also be added as part of a case update by setting the comment parameter.

Closing a case

Closing a case is a separate transition, which also triggers other notifications. When closing the case, an optional comment can be added to the case.

curl -X PUT -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/123456/close -d '{
  "comment": "Closing this case"
}'

See Swagger API documentation for details on valid request parameters.

Searching for cases

Searching for cases can be done using the simple search GET endpoint or the advanced search POST endpoint.

Simple search

For simple search, the valid filtering parameters can be added as query parameters, which will ANDed together for each parameter.
If any parameter name is repeated, all the values for that parameter name will be combined into one disjunction (OR-statement)

# search for cases with service "ids", customer "mycustomer" and status pendingSoc
curl -X GET -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case?service=ids&customer=mycustomer&status=pendingSoc

# search for cases with service "ids", which are bound to either customer ID 1 or 2
curl -X GET -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case?service=ids&customer=1&customer=2

Advanced search

Advanced search has access to all possible filtering parameters for case, and follow the general advanced search structure as described in the General integration guide.

As described there, multiple parameters in one criteria object are ANDed together. Multiple values for a single parameter are ORed together.

# search for cases with service "ids", customer ID 1 or 2, status "pendingCustomer" or "waitingCustomer" and some keyword match for the word "test"
curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/search -d '{
  "service":["ids"],
  "customer":[1,2],
  "status":["pendingCustomer","waitingCustomer"],
  "keywords":["test"]
}'

See Swagger API documentation for more details on valid request parameters.

Subcriteria

Subcriteria are discussed in detail in the General integration guide. We provide some examples related to the Case API here, but the concepts for subcriteria are described more in detail there.

Using subcriteria allows you to fetch several different dimentions of data in one query, or express which data to exclude. By default, subqueries will be combined with an "OR" logic.

# search for cases that either have status "pendingSoc" OR have priority "high". The customer criteria applies to both the subcriteria.
curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/search -d '{
  "customer":["mycustomer"],
  "subCriteria": [
     {"status":["pendingSoc"]},
     {"priority":["high"]},
   ]
}'

Exclude subcriteria

Subqueries with exclude=true, defines a set of criteria for cases to exclude.

# search for cases for customer mnemonic, and exclude those with status "pendingSoc" or "pendingCustomer"
curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/search -d '{
  "customer":["mnemonic"],
  "subCriteria": [
     {"exclude":true,"status":["pendingSoc","pendingCustomer"]}
   ]
}'

# search for cases for customer ID 1, and exclude those with status "pendingSoc" or "pendingCustomer"

curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/search -d '{

  "customer":[1],

  ...

  "subCriteria": [

     {"exclude":true,"status":["closed"}

   ]

}'

Searching for cases by user

Each case has a number of user-related fields:

• reporter
• assigned user
• assigned tech
• creator (generally equal to reporter)
• publisher (generally equal to reporter)
• last updated by user
• closed by user
• all users who have added comments

To search for cases across these fields, use the "userID" search parameter. By default, it will search across all these fields for cases where the userID parameter contains a user listed in one of these fields.

# search for cases where userID 1, 2 or 3 are listed in any of the user fields
curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/search -d '{
  "userID":[1,2,3],
  ...
}'

To search for cases by specific users in specific fields, use the parameter userFieldStrategy, which determines which field(s) to search. 

# search for cases which were created by userID 1, 2 or 3
curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/search -d '{
  "userID":[1,2,3],
  "userFieldStrategy": ["createdByUser"]
  ...
}'

See Swagger API documentation for more details on valid search parameters.

Searching for cases by time

Please see the General integration guide for examples and details on use of the startTimestamp, endTimestamp and timeFieldStrategy fields.

Searching for cases by keywords

Please see the General integration guide for examples and details on use of the keywords, keywordMatchStrategy and keywordFieldStrategy fields.

Managing comments

Listing comments

Comments on a case can be listed using the comments endpoint:

#fetch comments, default limit of 25
curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/comments
#fetch all comments
curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/comments?limit=0

Adding a comment

Simply add a comment to a case:

#fetch comments, default limit of 25
curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/123456/comments -d '{
  "comment":"My comment"
}'

Fetching events

To fetch events for a case, use the Events endpoint https://api.mnemonic.no/events/v1/case/<caseid>

See Event Integration Guide

Managing attachments

Listing attachments

Attachments on a case can be listed using the attachments endpoint. This will return metadata about the attachments.

#fetch metadata about attachments, default limit of 25
curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/attachments
#fetch metadata about all attachments
curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/attachments?limit=0

Downloading an attachment

To download the contents of an attachment, use the attachment download endpoint. This will return the raw attachment, with the same content-type as the attachment originally uploaded.

#fetch raw attachment
curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/attachments/12345678-1234-ABCD-123456789ABC/download > /tmp/attachmentfile

Adding an attachment

To upload an attachment, the attachment must be added to a base64-encoded POST request:

#upload attachment to case
curl -XPOST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json"  https://api.mnemonic.no/cases/v2/case/123456/attachments -d '{
  "name": "filename.log",
  "mimeType": "text/plain",
  "data": "YWJjZGVm"
}'

The data parameter is a base64-encoding of the binary attachment file.

Understanding case access

Access to cases is by default roleBased, meaning that users with rolebased access to the customer and service of the case, has access to it. There are different roles for read and write access, and a separate role for "tech users", generally meaning users representing the service provider.

A case can be given restricted access mode, meaning that access to customer users are explicit, and not rolebased. Tech users will still have normal access to the case. This use case is for cases which are handled by the service provider as normal, but which are sensitive for the customer.

The explicit access mode means that only users/user groups which are on the explicit access list have access to the case. This also applies to tech users.
Note: System administrators may still access the case without explicit access.

The explicit access list may also extend normal role based access, by giving explicit users/user groups access to a case, which do not have role based access to the case at all.

Access levels

For each individual case, a user may be granted one of the following access levels, depending on role-based and/or explicit access settings:

• Read privileges 
  • permits fetching all case details
• Write privileges 
  • Read privileges
  • updating case priority, status, reference, category, assignedUser
  • adding comments
  • adding/removing tags, links and attachments.
• Owner privileges
  • Write privileges
  • changing access mode
  • granting/revoking access
  • changing the reporter of a case (implicit owner)
  • changing subject and description on the case
  • changing watcher settings for other users

This table maps out which users get these roles:

Access roles

In addition to access levels, there are also a set of access roles: user, tech and admin.

User role

All users with read and/or write access to a case, assume the "user" role.

Tech role

Users with the role "tech" have additional privileges, which ordinary users do not:

• update restricted fields
• view or create internal comments
• update case workflows
• create an "unpublished" case, which are not visible to non-tech users
• publish an "unpublished" case
• change watcher settings for other users.
• delete comments and see deleted objects

Any change to the case also requires access level "write". A tech user with only "read" access level, can only view additional information.

Admin role

Users with the admin role have additional privileges, which users and techs do not

• assume "owner" role for the case, allowing override of case access settings and explicit access grants.
• users with "admin" role always have full write access level (implied by "owner"), as well as "tech" role.

Determining access level and role

To see which access level the current user has on a particular case, each case contains a field "currentUserAccess":

"currentUserAccess": {
  "level": "write",
  "role": "user"
}

• The field "level" may return "read", "write" or "owner". Write implies read. Owner implies both read and write.
  • If the user has no read access, the case will not be returned from the API
• The field "role" may return "user", "tech" or "admin". Tech implies user. Admin implies both tech and user.

Changing case access mode

To change the access mode of a case, use the access PUT endpoint:

curl -X PUT -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json"  https://api.mnemonic.no/cases/v2/case/123456/access -d '{
  "accessMode": "readRestricted"
}'

Granting case access

To grant access to a case for a user or user group, POST to the access endpoint with the subjectID of the user or group. The level parameter will determine the level of access granted to that user or group.

curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json"  https://api.mnemonic.no/cases/v2/case/123456/access -d '{
  "subjectID": <userID>,
  "level": "read"
}'

List case access

Depending on the case accessMode, different users have role-based access to the case, according to the table above. Use the Get case endpoint to see the accessMode of a case.

Explicit access granted to single users or user groups can be listed using the access endpoint:

curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/access

Revoking case access

To revoke access from a user on the case ACL, use the DELETE access endpoint with the ID of the ACL entry to delete:

curl -X DELETE -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/access/c2134bd3-9d88-4d6c-a395-d8d2241b4cbd

Managing case tags

Tags are a kind of labels to add structured keywords to cases. Each tag has a key and a value. A case may have multiple tags, and even multiple tags with the same key.

Listing tags

#fetch tags, default limit of 25
curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/tags
#fetch all tags
curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/tags?limit=0

Tags are returned with some metadata:

{
...
"data": [
  {
    "id": "c2134bd3-9d88-4d6c-a395-d8d2241b4cbd",
    "addedTimestamp": 1520800381632,
    "addedByUser": {...},
    "key": "mykey",
    "value": "myvalue1",
    "flags": []
  },
...
]
}

Adding a tag

#adds two tags, key=value1 and key2=value2
curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/123456/tags -d '{
  "tags":["mykey/value1", "mykey2/value2"]
}'
#equivalent, using the full tag encoding
curl -X POST -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/123456/tags -d '{
  "tags":[
    {"key":"mykey", "value":"value1"}, 
    {"key":"mykey2", "value":"value2"}, 
  ]
}'

Removing a tag

A tag can be removed by key/value, or by the ID of the tag itself.

curl -X DELETE -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/tags/mykey/value1
#equivalent, using the tags ID
curl -X DELETE -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/case/123456/tags/c2134bd3-9d88-4d6c-a395-d8d2241b4cbd

Moving a case

This endpoint is used to change the case type, service or customer of a service.

This example moves the case to the service ids for customer "newcustomer":

curl -X PUT -H "Argus-API-Key: my/api/key" -H "Content-Type: application/json" https://api.mnemonic.no/cases/v2/case/123456/move -d '{
  "customer": "newcustomer",
  "service": "ids",
  "type": "securityIncident"
}'

Required permissions

See Swagger API documentation for details on valid request parameters.

Fetching services

To list possible services to submit to, and which case types they support, use the services endpoint:

curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/service
# will return
{
  "data": [
    "id": 6,
    "shortName": "support",
    "caseTypes": ["operationalIncident", "securityIncident", "change", "informational"],
    ...
  ],
  ...
}

To fetch only a specific service, you can use the service GET endpoint https://api.mnemonic.no/cases/v2/service/ID where ID can be the service numeric ID or shortname.

Fetching service subscription

To use a specific service, a customer must have a valid service subscription. To check which service subscriptions a customer has, use the servicesubscription endpoint with a "customer" query parameter:

curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/servicesubscription?customer=mnemonic
# will return
{
  "data": [
    "id": "010afb43-323e-463a-a3fc-e93336488798",
    "service": {
        "id": 2,
        "name": "Security Monitoring",
        ...
    },
    "customer": {
        "id": 1,
        "name": "mnemonic",
        ...
    },
    ...
    "currentUserAccess": {
        "level": "write",
        "role": "user"
    }
    ...
  ],
  ...
}

Fetching categories

To list available categories, use the category endpoint:

curl -H "Argus-API-Key: my/api/key" https://api.mnemonic.no/cases/v2/category
# will return a list of categories
{
  "data": [
    {
      "id": 61,
      "name": "Firewall operational incidents",
      "shortName": "firewall-operational",
      ...

      "bindings": [
        {
          ...
          "service": {
            "id": 6,
            "name": "Support",
            "shortName": "support"
          },
          "caseTypes": [
            "operationalIncident"
          ]
        }
      ],
      ...
    }
  ],
  ...
}

The category listed specify valid bindings to services and case types. In the example above, the category "firewall-operational" is bound to the service support, for case type operationalIncident. This means that it is valid to use for cases with this service and caseType.

One category may specify multiple bindings, and possibly multiple case types per binding.

To fetch only a specific category, you can use the category GET endpoint https://api.mnemonic.no/cases/v2/category/ID where ID can be the category numeric ID or shortname.
