Capabilities

Tools 24

civicrm_add_contact_note

WRITE: adds ONE note to a contact's record, written by the contact this API key belongs to. Sends nothing. APIv4 Note.create.

Discovered
civicrm_add_contact_to_group

WRITE: adds ONE contact to ONE static group. If the group is used as a mailing list, the contact will receive future mailings sent to it, so only add people who agreed. Sends nothing by itself. Adding a contact who is already in the group changes nothing; a contact who was removed from it (or is pending) is set back to Added. APIv4 GroupContact.save matched on group and contact.

Discovered
civicrm_create_contact

WRITE: creates ONE new contact (an individual, organization or household) and optionally its first e-mail address and phone number. Does not check for duplicates: search first with civicrm_search_contacts. Sends nothing. APIv4 Contact.create, Email.create, Phone.create.

Discovered
civicrm_create_membership

WRITE: gives ONE contact a membership of a type. CiviCRM works out the dates and status from the type unless you give dates. It does NOT record a payment (use civicrm_record_contribution for that) and sends nothing. APIv4 Membership.create.

Discovered
civicrm_get_contact

One contact by id: name, type, job title, source, communication preferences (do not e-mail, opted out, ...), dates, plus all their e-mail addresses, phone numbers and postal addresses. APIv4 Contact.get, Email.get, Phone.get, Address.get.

Discovered
civicrm_get_fields

The fields of one CiviCRM entity (Contact, Contribution, Event, ...) including custom fields: name, label, data type, whether required, and the allowed options for a pick-list field. Use it to find the right field names for civicrm_query and the right option names for the filters and write tools. APIv4 <Entity>.getFields.

Discovered
civicrm_list_activities

Activities (meetings, phone calls, e-mails, follow-ups, ...) with type, subject, status, date and details, newest first. With contact_id: the activities that contact took part in, with their role (source, target or assignee). Otherwise all activities, optionally of one type or status. APIv4 ActivityContact.get / Activity.get.

Discovered
civicrm_list_cases

Cases (CiviCase) with subject, case type, status and dates. With contact_id: the cases that contact is a client of. Needs the CiviCase component to be enabled. APIv4 CaseContact.get / Case.get.

Discovered
civicrm_list_contact_notes

The notes recorded on one contact (subject, text, who wrote it, when), newest first. APIv4 Note.get.

Discovered
civicrm_list_contributions

Contributions (donations, membership dues, event fees) with contact, amount, currency, financial type, status, payment method, date and source, newest first. Filter by contact, status, financial type, date range and minimum amount. Test contributions are left out. APIv4 Contribution.get.

Discovered
civicrm_list_entities

The APIv4 entities this CiviCRM site offers (Contact, Contribution, Event, plus those of installed extensions), with a short description. Use the names with civicrm_get_fields and civicrm_query. APIv4 Entity.get.

Discovered
civicrm_list_events

Events with title, type, start and end date, whether active and public, maximum participants and summary. Upcoming events first when upcoming_only is set. Template events are left out. APIv4 Event.get.

Discovered
civicrm_list_group_contacts

Discovered
civicrm_list_groups

Contact groups (mailing lists, static groups, smart groups) with title, description, visibility and type. APIv4 Group.get.

Discovered
civicrm_list_memberships

Memberships with contact, membership type, status (New, Current, Grace, Expired, ...), join, start and end date. Filter by contact, status, type, or those ending before a date (renewal follow-up). Test memberships are left out. APIv4 Membership.get.

Discovered
civicrm_list_participants

Event registrations with event, contact, status (Registered, Attended, Cancelled, ...), role, registration date and fee. Filter by event, contact or status. Test registrations are left out. APIv4 Participant.get.

Discovered
civicrm_list_relationships

The relationships of one contact (employee of, spouse of, volunteer for, ...) with the other contact, start and end date and whether it is active. APIv4 Relationship.get.

Discovered
civicrm_log_activity

WRITE: records ONE activity (a meeting, phone call, e-mail, follow-up, ...) with one or more contacts. It only STORES the record: an activity of type Email does not send an e-mail. Added by the contact this API key belongs to unless source_contact_id is given. APIv4 Activity.create.

Discovered
civicrm_query

Read records of ANY CiviCRM entity with APIv4 Entity.get: choose fields, filter, sort and page. Use civicrm_list_entities and civicrm_get_fields for the names. Field names may be joined (`contact_id.display_name`, `email_primary.email`) or ask for an option's text (`status_id:label`). Examples: entity Tag; entity Campaign with where [{field:'is_active',op:'=',value:true}]; entity Contribution with select ['id','total_amount'] and where [{field:'total_amount',op:'>=',value:1000}]. Read-only; credential fields and system entities (settings, payment processors, mailings, users) are refused.

Discovered
civicrm_record_contribution

WRITE: records ONE contribution (a donation, a payment received elsewhere) for a contact. It only STORES the financial record: no card is charged, no receipt is e-mailed, and the amount shows up in CiviCRM's reports and the contact's giving history. Check civicrm_list_contributions first to avoid a duplicate. APIv4 Contribution.create.

Discovered
civicrm_register_participant

WRITE: registers ONE contact for ONE event (a participant record). It does not check the event's capacity or fee, does not take payment and sends no confirmation e-mail. APIv4 Participant.create.

Discovered

Discovered
civicrm_update_contact

WRITE: changes basic fields of ONE existing contact (name, job title, source, preferred language) and/or its communication preferences (do not e-mail, do not phone, do not mail, do not SMS, opted out of bulk mail). Only the fields you give are changed. Setting a do-not flag to false re-enables contact the person may have declined, so only do that on the person's request. APIv4 Contact.update.

Discovered
civicrm_whoami

The CiviCRM contact this API key belongs to (contact id, display name, contact type) and how it authenticated. Everything the other tools do is limited to that contact's permissions. GET /civicrm/authx/id, then APIv4 Contact.get.
