When creating, retrieving, or updating data, you can use the fields query parameter to include additional fields that are not included in the API response by default.
To use the fields query parameter, append ?fields={fieldName} to the end of the request URL. To include multiple fields in the API response, separate each key-value pair with an ampersand (&). For example, to include data for associated Groups and Tags in an API response, append ?fields=associatedGroups&fields=tags to the end of the request URL.
Send a request in the following format to retrieve a list of fields you can include in responses returned from an object's endpoint:
OPTIONS /v3/{objectType}/fieldsFor example, the following request will retrieve a list of fields you can include in responses returned from the /v3/indicators endpoint:

Phishing can be targeted, known as spearphishing. In spearphishing, a specific individual, company, or industry will be targeted by the adversary. More generally, adversaries can conduct non-targeted phishing, such as in mass malware spam campaigns.\n\nAdversaries may send victims emails containing malicious attachments or links, typically to execute malicious code on victim systems. Phishing may also be conducted via third-party services, like social media platforms. Phishing may also involve social engineering techniques, such as posing as a trusted source, as well as evasive techniques such as removing or manipulating emails or metadata/headers from compromised accounts being abused to send messages (e.g., [Email Hiding Rules](https://attack.mitre.org/techniques/T1564/008)).(Citation: Microsoft OAuth Spam 2022)(Citation: Palo Alto Unit 42 VBA Infostealer 2014) Another way to accomplish this is by forging or spoofing(Citation: Proofpoint-spoof) the identity of the sender which can be used to fool both the human recipient as well as automated security tools.(Citation: cyberproof-double-bounce) \n\nVictims may also receive phishing messages that instruct them to call a phone number where they are directed to visit a malicious URL, download malware,(Citation: sygnia Luna Month)(Citation: CISA Remote Monitoring and Management Software) or install adversary-accessible remote management tools onto their computer (i.e., [User Execution](https://attack.mitre.org/techniques/T1204)).(Citation: Unit42 Luna Moth)",

}When using the fields query parameter, you can request additional association levels for a field by appending .{fieldName} to the field's name.
For example, the following request will retrieve data for the Indicator whose ID is 4 and include Groups associated to the Indicator and Attributes added to those Groups in the response. To accomplish this, ?fields=associatedGroups.attributes is appended to the end of the request URL.

}By default, you can retrieve only one association level at a time. To retrieve more than one association level at a time, contact your System Administrator and have them complete one of the following actions:
- Enable the Allow User to Exceed API Link Limit setting on your API user account. Instructions for enabling this setting are available in the "Creating an API User Account" section of the Creating User Accounts knowledge base article.
- Update the v3 API link limit in system settings to allow for more than one association level to be retrieved at a time.
The following example demonstrates how to retrieve two association levels in a single request. The request will retrieve data for the Indicator whose ID is 4 and include the following data in the API response:
- Groups associated to the Indicator
- Attributes added to those Groups (the first association level)
- Security Labels applied to those Attributes (the second association level)
To accomplish this, ?fields=associatedGroups.attributes.securityLabels is appended to the end of the request URL.

}Responses for some objects include a createdBy field, which includes subfields that provide details about the user who created the object. By default, the createdBy field includes the following subfields:
idusernamefirstNamelastNamepseudonymowner
To include more details about the user that created an object, append ?fields=userDetails to the end of the request URL. Note that additional subfields will be included within the createdBy field only for API users with Read permission for user accounts (i.e., API user accounts with an Organization role of Organization Administrator).
For example, the following request will retrieve data for the Group whose ID is 12 and return additional details about the user who created the Group.

}You can combine the tql and fields query parameters in a single API request, allowing you to filter results using ThreatConnect Query Language (TQL) and include additional fields in the API response.
For example, the following request will retrieve data for all Indicators with a Threat Rating greater than or equal to 4 and include data for Tags and Attributes added to each Indicator in the API response.
Request (Decoded URL)
GET /v3/indicators?tql=rating GEQ 4&fields=tags&fields=attributesRequest (Encoded URL)
GET /v3/indicators?tql=rating%20GEQ%204&fields=tags&fields=attributesNote
Depending on the tool you are using to interact with the ThreatConnect API, it may be necessary to encode the request URL manually if it includes query parameters. For example, some tools may accept /v3/indicators?tql=ownerName GEQ 4&fields=tags&fields=attributes as a valid request URL and encode it automatically, while others may require you to encode the request URL manually. If you send a request with query parameters and a 401 Unauthorized error is returned, verify whether the request URL is encoded properly for the API tool you are using.
