App authoring API

Use the Splunk SOAR app authoring API to write applications that interact with external devices and create structured results, which are then passed onto the Splunk SOAR core to be displayed in the SOAR UI and consumed by SOAR playbooks. The complete set of APIs can be logically divided into the following groups:

• BaseConnector
• ActionResult
• Vault

BaseConnector

add_action_result(action_result)

Adds an ActionResult object into the connector run result. Returns the object added.

Parameter	Required	Description
action_result	Required	The ActionResult object to add to the connector run.

append_to_message(message)

Appends a string to the current result message.

Parameter	Required	Description
message	Required	The string to append to the existing message.

debug_print(tag, dump_object='')

Dumps a pretty printed version of the 'dump_object' in the <syslog>/phantom/spawn.log file, where <syslog> typically is /var/log/.

Parameter	Required	Description
tag	Required	The string that is prefixed before the dump_object is dumped.
dump_object	Optional	The dump_object to dump. If the object is a list, dictionary and so on it is automatically pretty printed.

error_print(tag, dump_object='')

Dumps an ERROR as a pretty printed version of the 'dump_object' in the <syslog>/phantom/spawn.log file, where <syslog> typically is /var/log/. Do not use this API to dump an error that is handled by the App. By default, the log level of the platform is set to ERROR.

remove_action_result(action_result)

Removes an ActionResult object from the connector run result. Returns the removed object.

Parameter	Required	Description
action_result	Required	The ActionResult object that is to be removed from the connector run.

Save an artifact to .

Parameter	Required	Description
artifact	Required	Dictionary containing information about an artifact.

Returns the following tuple

Parameter	Description
status	phantom.APP_SUCCESS or phantom.APP_ERROR.
message	Status message.
id	Saved artifact ID if success.

Save artifacts more efficiently with the save_container API, since a single function call can add a container and all its artifacts.

See Active playbooks at the end of this section to learn how to set the run_automation key in the artifact dictionary.

save_artifacts(artifacts)

Save a list of artifacts to .

Parameter	Required	Description
artifacts	Required	A list of dictionaries that each contain artifact data. Don't set the run_automation key for the any artifacts, because the API will automatically set this value to 'False' for all but the last artifact in the list to start any active playbooks after the last artifact is ingested.

Returns the following tuple:

Parameter	Description
status	phantom.APP_SUCCESS or phantom.APP_ERROR.
message	Status message.
id_list	List of saved artifact IDs if successful; none otherwise.

Save artifacts more efficiently with the save_container API, since a single function call can add a container and all its artifacts.

See Active playbooks at the end of this section to learn how to set the run_automation key in the artifact dictionary.

save_container(container)

Save a container and artifacts to .

Parameter	Required	Description
container	Required	Dictionary containing info about a container. To ingest a container and artifacts in a single call, add a key called artifacts to the container dictionary. This key contains a list of dictionaries, each item in the list representing a single artifact. Don't set the run_automation key for the container or artifacts. The API will automatically set this value to 'False' for all but the last artifact in the list to start any active playbooks after the last artifact is ingested.
fail_on_duplicate	Optional	Affects behavior when attempting to save a container that is an exact duplicate of an existing container. When True, returns phantom.APP_ERROR When False or not provided, returns phantom.APP_SUCCESS

Returns the following tuple

Parameter	Description

save_containers(containers)

Save a list of containers to the phantom platform.

Parameter	Required	Description
containers	Required	A list of dictionaries that each contain information about a container. Each dictionary follows the same rules as the input to save_container.
fail_on_duplicate	Optional	Affects behavior when attempting to save a container that is an exact duplicate of an existing container and no other containers in the group were successfully saved. When True, returns phantom.APP_ERROR When False or not provided, returns phantom.APP_SUCCESS

Returns the following tuple:

Parameter	Description
status	phantom.APP_SUCCESS or phantom.APP_ERROR. This is successful when at least one container is successfully created.
message	Status message
container_responses	A list of responses for each container. There will be one response for each container in the input list. This is a dictionary with the following keys: success (phantom.APP_SUCCESS or phantom.APP_ERROR), message, and id.

This is the most performant API to use during ingestion, as you can create all the artifacts and containers at once.

As long as at least one container is successfully added, the status is success. During ingestion, BaseConnector automatically keeps track of how many containers and artifacts are successfully added, though if you do want to know more about an individual failure you need to iterate over the list in the response and check the message.

save_progress(progress_str_const, *unnamed_format_args, **named_format_args)

Parameter	Required	Description
state_dict	Required	The dictionary to write to the state file.

send_progress(progress_str_const, *unnamed_format_args, **named_format_args)

This function sends a progress message to the Splunk SOAR core. It is written to persistent storage, but is overwritten by the message that comes in through the next send_progress call. Use this function to send messages that need not be stored over a period of time like percent completion messages while downloading a file.

set_status_save_progress(status_code, status_message='', exception=None, *unnamed_format_args, **named_format_args)

Helper function that sets the status of the connector run. This needs to be phantom.APP_SUCCESS or phantom.APP_ERROR. This function sends a persistent progress message to the Splunk SOAR Core in a single call. Returns the status_code set.

Parameter	Required	Description
status_code	Required	The status to set of the connector run. It is either phantom.APP_SUCCESS or phantom.APP_ERROR.
status_message	Optional	The message to set. Typically, this is a short description of the error or success.

update_summary(summary)

Update the connector run summary dictionary with the passed dictionary.

Parameter	Required	Description
summary	Required	The Python dictionary that needs to be updated to the current connector run summary.

Active playbooks

This section provides additional information for save_artifact, save_artifacts, and save_container, described earlier.

In , playbooks marked as active are automatically run when a container is added or updated. Adding any artifact to a container is considered updating the container.

The container and artifact dictionaries support a key named run_automation. When this key is set to 'True' active playbooks are run. For best results, set run_automation to 'True' only for the last artifact of the container.

The save_container and save_artifacts APIs set the run_automation key to 'False' for all except the last artifact, to run the playbook once per container after all artifacts are ingested. Based on this behavior, using the save_container and save_artifacts APIs is preferable to using the save_artifact API, which sets the run_automation key to 'False' if not already set.

ActionResult

Vault

During the execution of any action other than test connectivity, the app can add attachments to a container. These files are placed in the vault, which is a location within each container. The app requires the container id to add a file in the vault. The BaseConnector::get_container_id() API can be used to get this information.

Every vault item within a container is denoted by a vault_id.

Most vault APIs are defined directly as functions in the phantom.vault module. The create_attachment and get_vault_tmp_dir APIs are defined as class methods of the Vault class within the phantom.vault module.

The vault_delete API deletes one or more objects from the vault. Deletes either the "first matching object" or "all matching objects", based on the specified remove_all criterion

Parameter	Required?	Description
vault_id	Optional	The sha1 file hash of the vault file contents, such as 41c4e1e9abe08b218f5ea60d8ae41a5f523e7534.
file_name	Optional	The file name of the vault file.
container_id	Optional	Container ID to query vault items for. To get the current container_id value from an app that is executing an action, use the return value of BaseConnector::get_container_id().
remove_all	Optional	Set to 'True' to delete all vault files that meet the provided criteria. Set to 'false' to delete only the first vault file that meets the criteria.
trace	Optional	Set to 'True' to return debug information.

vault_info(vault_id=None, file_name=None, container_id=None, trace=False)

The vault_info API returns a tuple; of a success flag either True or False, any response messages as strings, and information for all vault items that match either of the input parameters as a list. If neither of the parameters are specified, an empty list is returned.

Parameter	Required?	Description

Vault.create_attachment(file_contents, container_id, file_name=None, metadata=None)

Creates a file with the specified contents, and add that to the vault. Returns the object added. This API is the same as vault_add, but it accepts file_contents, rather than a file_location,

Parameter	Required	Description
file_contents	required	The contents of the file. A temporary file with these contents will be created, which will then be added to the vault.
container_id	required	This is the container to add the attachment to. The return value of BaseConnector::get_container_id() is sufficient.
