Same records as the REST ActivityRelations entity. REST: [ActivityRelations](https://developers.coevera.com/reference/rest/activity-relations.md). ## Queries - `getById(entityId: ID!): ActivityRelationEntity` Returns the record with the given id, or null when there is none. Deleted records are returned as well. - `getByIds(entityIds: [ID!]!): [ActivityRelationEntity!]!` Returns the records with the given ids; ids without a record are left out. Deleted records are returned as well. - `getAll(limit: Int, offset: Int, filter: ActivityRelationFilterInput, orderBy: [ActivityRelationOrderByInput!], includeDeleted: Boolean): [ActivityRelationEntity!]!` Returns the records that match the filter, paged with limit and offset. - `getByCriteria(filter: ActivityRelationFilterInput, orderBy: [ActivityRelationOrderByInput!], includeDeleted: Boolean, before: String, after: String, first: Int, last: Int): ActivityRelationEntityConnection` Returns the records that match the filter as a cursor-paginated connection. - `getChangedFieldsSinceRevision(id: UUID!, revision: Int!): [UUID!]!` Returns the ids of the fields of a record that changed after the given revision. Returns an empty list for entities without change tracking. ## Mutations - `createActivityRelation(input: CreateActivityRelationInput!, validationLevel: [ValidationLevel!]): CreateActivityRelationPayload` Create one record. - `updateActivityRelation(input: UpdateActivityRelationInput!, validationLevel: [ValidationLevel!], sessionIdToUpdate: String): UpdateActivityRelationPayload` Update fields. - `bulkUpdateActivityRelation(input: [CreateOrUpdateActivityRelationInput!]!, deleteInput: [DeleteActivityRelationInput!], validationLevel: [ValidationLevel!], rollbackMethod: RollbackMethod, match: MatchingInput): BulkUpdateActivityRelationPayload` Create or update many; per-item results. - `deleteActivityRelation(input: DeleteActivityRelationInput!): DeleteActivityRelationPayload` Soft-delete. ## Types ### ActivityRelationEntity (object) Link of a task or an appointment to a record it concerns, such as an account, contact, lead, opportunity, project or quote. - `isDeleteProtected: Boolean!` True when the record is protected against deletion because it must always exist in the space.

Types several repositories share, such as `PageInfo` and the filter fields, are in the [types index](https://developers.coevera.com/reference/graphql/types.md). The [SDL](https://developers.coevera.com/graphql/schema.graphql) has the whole schema in one file. ## Example ```graphql query FirstActivityRelations { entities { activityRelation { getByCriteria(first: 3, orderBy: [{ modified: Desc }]) { totalCount edges { node { id modified } } } } } } ``` ```bash curl 'https://{region}.api.coevera.com/api/v100/app/space/{space_id}/graphql/public' \ --user "$COEVERA_API_KEY:$COEVERA_API_SECRET" \ --header 'Content-Type: application/json' \ --data '{"query":"query FirstActivityRelations { entities { activityRelation { getByCriteria(first: 3, orderBy: [{ modified: Desc }]) { totalCount edges { node { id modified } } } } } }"}' ```
